Horizon Hobby - Carbon Cub S 2 - Flap Install & Flight 

Brian has become my "go to" for almost everything in RC planes. I am disappointed when I can't find a plane I want to buy or update or learn almost anything on RC planes. The most detailed information out there. Thank you for all of your help. I wish I had found you sooner!

Just so you know, these are the only videos, over 1 hour, on RU-vid, that not only do I watch, but rewatch.

Great work as always, your “how-too’s” are very informative, always learn something from ya buddy, thanks for all the work👍🏼👍🏼👍🏼👊🏼👊🏼

Thank you again for the thorough explanations. I installed my flaps yesterday. The radio setup on thee NX8 was a bit different from what you showed, but your guidance helped immensely in deciphering the Spektrum manual. There was no mystery at all in coordinating the flap and elevator deployment speed. The Flap System control page is awesome. After getting the servo and switch assigned correctly everything else can be done from that page. The position of the servo/switch is controlled by a value, -100 to 100, for both ends and the center position. What I found is that I could “reverse” the servo just by swapping the sign in the endpoints. The elevator position was similarly easy to set and so after experimenting and finding that positive values deflected pitch down, I set those to a conservative 10% (half flaps) and 20%. When the winds calm I’ll test and adjust those for perfect balance. I watched you theorize a way to get elevator deployment to synchronize (time delay) with the flaps. I know you have an NX8 now so switch to that and there is nothing extra needed. When you set the elevator deflection in the Flap System page the timing is handled for you. My flaps and elevator deploy at the same speed. Perfect! Why 4 seconds? I timed the flap deployment on my Cirrus and found it is about 2 seconds to go from none to half, and another 2 to go from half to full. When I had a 185 I always deployed the flaps with some finesse (hand operated flap lever). Flap deployment and retraction initiate significant pitch diversions. Rapid flap deployment near the runway would likely result in some dangerous excursions. Rapid flap retraction at low speeds can cause an immediate stall, with no warning buffet. Below 1,000 feet (real airplane) that is deadly. So the long and short of it is I want the little model to behave well, like a real airplane. Are you also a pilot or student pilot?

Thanks for the video Brian. I just received my Cub and wanted to set up the flaps. Your "how to" video will make this a WHOLE lot easier. And I am a noobie, with some experience on a park flyer mini.

Thanks so much for proving that it was compatible, I look forward to getting my flaps all set up!

Always find myself subconsciously always making sure throttle cut is on! Partly due to you I’d imagine. Great video as always.

Brian thanks for showing this plane off, I bought this plane after I bought the T-28 because I was too worried to fly the T-28 and wreck it. This plane is a breeze to fly, but the wing creates so much lift it becomes difficult to land it in safe when there is wind, you don’t have enough down elevator to overcome the lift. It’s so confidence inspiring that I’ve actually been practicing flying without safe more and more. I figure a couple dozen more flights with this plane and I’ll celebrate with the maiden flight of the T-28. Thanks again for bringing all the excellent content and making it so exciting to watch. You and the camera crew Keep up the great work!

Just completed my maiden flight. Was pretty nervous but the flap install is a game changer. Makes take off and landing so much easier and slows it down in the air. Perfect for beginners. Got the bug now! Thank you so much for the videos. Flaps work fine with the RTF transmitter included.

Thank you so much for adding this to the CC playlist !

Seen MANY of your vids since bein stuck @ home for a few days. Thanks! Believe this has gotten me back after getting out of R/C since 96 (started w/a Kyosho Wildcat buggy in '83). This model is what I've decided to go w/ to return...

Thanks for the video! I’ve been wanting flaps on the cub because we had a spare servo, but I thought it wouldn’t work with the dxs. But thanks to this video I now have flaps on the cub using the dxs

Great video, Brian. I knew you'd love the flaps on that thing. The flare is a little sluggish with the flaps when you're landing, so I upped my elevator throw and problem solved. I noticed you were greasing your landings at the end. Well done.. Now that's how you keep your pants on!

I was watching some Trent Palmer videos this afternoon and installing a flap servo on my Cub came to mind. Perfect!

Hello Brian and Mrs Megan aka camera crew, as always well done. Love the carbon cub. Its an everyday flyer. Flaps make the plane different on flying. Thanks for the video keep flying you guys. Just having fun RC'n with friends and family members

Added flaps today. Thanks for the video. It was very helpful!

Great job. I recently purchased this plane as used ( with flaps) with a DXs and your video has helped me understand this plane and transmitter. Thank you.

Awesome little plane. Even for an experienced pilot like myself this would be a nice relaxing flyer. I would even add that landing sensor because I love the technology. One doesn't really need flaps, but it was a good idea to enable them anyway. Thanks for your reviews.

Hello Brian, I'm glad that you have installed flaps on this plane. Listening to your in-flight commentary, you use flaps more than anybody else that is flying. So, it is very good for you to have them. I got to say, this plane is very good looking. Not as sexy as a P-51 1700mm, but a looker none the less. " Hey! "

Loving the videos here in the UK ! Just bought a cub s2 so I’m really interested in how you’ve done the flap addition and basic flying 👍

Back in the hobby after 30-plus years, lol. Loving my Carbon Cub and the flaps makes it that much better.

Thanks for the detailed install especially using the servo tester to position the flaps. Other videos do not come close.

Good video! When you know the instructions can't be right, its great to have a video of someone who knows what they're doing, to reference! Also great that this RTF plane came with an option that once installed, practically shouts that you now have a good excuse to go buy a fancier transmitter! 🙂

Excellent Video Buddy. Doing my flap install now while watching your video

Thank you for all the info Bryan I like watching your videos I learn stuff

I love your method of balancing the prop without removal......going to balance several of my Horizon planes that way...TY

Thanks so much for making this video just got the plane and made the assembly so easy. Awesome plane

Outstanding as always, thank you guys. Hey your grass is coming in nice.

Just bought a used one of these planes, and I'm going to be doing this for sure! I may have to replace the receiver as well because it is not letting me bind it up properly, but the plane is in perfect condition so it should be worth the effort!

Good timing, I have the Carbon Cub S+ and installed the servo for the flaps, I am having difficulty adjusting my flap servo though....watching the video again...thanks for your efforts..

Got 2 1.2m p-51s and I just ordered this one, pretty sure I’ll have more fun w it than w the p-51s because of how smooth them things fly. Also thanks for this video because I’m sure I’ll need it to install the flaps 😂

👍 I agree with you there on the flaps, Horizon stop cutting corners, for the amount of money these planes cost ... Thanks Brian and camera crew for sharing and educating us on how to do this! I have learned a lot on RC from you're channel since i found you on the RU-vid world! ☠️ SEMPER Fi 🇺🇸🐾🐾🐾

GREAT VIDEO camera crew!

You'll have to give us a tour sometime of the hundreds of planes in the hanger/basement. I can only imagine!

Good video, and camera crew does a good job.

Brian, you shoulda been a high school teacher since you explain what you're doing very well. Another terrific video.

Ordered the S2 today and the servo thatawesome

...love all your videos you and camera crew make .....haven't bought one yet but just got thru watching the Carbon Cub S2 1.3 flap installation video and wonder does the "flap linkage" come with both the BNF and RTF versions? I searched on-line at Horizon and didn't see one that could be ordered. Thanks Kenny

I own the original version released over 5 plus years ago: the Carbon Cub SS with GPS. One of the greatest planes I’ve ever flown aside from the Timber line. I’ve never used gps or flaps and always had a great time.

Great video Brian and crew

“We’ve got good penetration” Great instructional video!

Thank you Brian nice job

Again a very usefull video from you! thanks! Also to the camera crew, she does a great job too and has a nice voice! Do you have any tips on make the flaps fixed? I do have the Dx6e and as beginner I'd like this bird to be slower.

Sound is great. Nice video.

Thanks for your opinion on buying a transmitter at first. I'm ready to get back into flying rc but now there's rtf . When I was flying it was all balsa and monocoat. I really appreciate your help.

Thank you for the great information! That was a lot of help for a beginner. Don't sweat the jokes; if you aren't having fun the videos won't be as fun.

awesome. thanks!

Thanks for checking the remote. I asked Horizon why exactly it wouldn't and this was the response: " Technically switch D could be used, but it is not recommended. Flaps requires a mixing function (FLP=ELE) to control the attitude when flaps are deployed. The DXS transmitter does not currently have a mixing function. Otherwise, channel 7 is available for auxiliary functions." I do find it interesting that they say the transmitter ‘currently’ does not have the mix feature making me think down the road we might be able to update it to do so.

Cheers Brian thanks for the advice mate

This plane made me come up with a new RC word.....SNAP RUDDER....amazing change of direction...almost immediately.

I love my carbon cub when I do actually fly it. I did wonder if putting a longer servo arm will actually give me more flap adjustment? My flaps do not work as well as yours do. Nice video thanks for putting it up

A person at the flying club had this plane but the first version. The wingstruts expanded so much because of heat that it became all wavy. But then one day he decided to fly it in 20 mph wind and he lost it. Never found it. He really liked it as the beginner he is

Thanks for this video, I was wanting to put flaps on my carbon s+ but couldn't find the servo horizon recommends. The metal gear servo you used I'll be looking to get for mine

We have several planes I had to go look at my cub to see if flap rods were in mine. We fly on dirt road that is in our peanut field. We fly Cubs with big tires our landings throw dust looks so cool. A Draco ultimate combo we ordered want be ready till January 2022. Like your show.

Brian, thank you very much for you detailed videos, which encourage me to use the flaps on the Carbon Cub S2. I will buy the Spektrum DX6e and I want to know if after doing the bind with the DX6e I could continue using the original DXs in case another people used it. Thanks. Manuel Gonzalez

Brian - thank you for your great videos!! I just started two weeks ago, and I’m loving it - bought this plane. I installed a 12g servo for the flaps today but it chatters a lot…is the servo too weak? Thanks again! Ryan

Thanks for the video Brian. I am going to be buying a eight channel radio and doing the flap upgrade to my carbon cub s+. Just can't make my mind up if I want to make my maiden flight now or wait until after the flap upgrade. And if I want to use GPS and auto land. I am a new pilot with very little flight experience.

Just ordered the S2 plus the Servo motor to add flaps. Also bought the 8 Channel Spectrum Radio (Programmable)

Love your video's. You and your wife are doing a great job. Question, I have the BNF version (installed flaps) with a NX8. If I set the Aircraft type to "Normal/Normal" SAFE works fine, all three modes. However I have NO Flap menu so I can't put in the Elevator correction for mid & full Flaps. If I set the Aircraft type to "1 Aileron/1 Flap" I then get the Flap menu & can make the Elevator corrections but the plane is locked in Basic SAFE mode only.

Brian thanks for taking the time on this video. I’m considering this plane as my first. One thing I’m confused about - I see that the flaps DO work on the RTF transmitter despite what it says in the manual. But is there some conflict with SAFE if you do this? I’m not quite sure I understood.

Hey Brian, another awesome video👍. I have the Sport Cub S2 it has a brush motor. Is there a motor I can upgrade too?. The upgrade horizon offers I saw some complaints on one of the parts isn't seated all the way or something and want to avoid that. Is there a different brushless motor that I could put in it?. Thanks man! You're seriously the best

Hi Brian Great vid as always , spoke to you last week about the Sport Cub 2 and thanks for all the info but this has thrown me a little bit I'm now wondering if I should get this as my first plane . I'm after a bit of advice as I've been told smaller planes are a lot harder to fly and the Sport Cub 2 is a lot smaller . Obviously you are a fantastic flyer and make both look very easy . In your opinion what would you recommend ? do you think I should stick with a Sports cub 2 ?, or go for the rtf Carbon Cub Thanks for your help

nice video!!!! thanks for show us how to put flaps working!!!! which one is easier to fly, Timber EVO or Carbon cub s2 with flaps?

I'm a beginner and just purchased this plane. I think I could manually set the flaps to FULL without getting a servo. I haven't flow the plane yet because of the weather here in Northern Minnesota where the high temp for today was -8 degrees. Really enjoy your videos!

Great video. Just assembled this plane. Haven't even flown it yet and I'm going to be taking the wing back off and upgrading to flaps. 😂 Servo, servo checker and double sided tape arrived yesterday. Thumbs down to horizon for not adding the what... maybe $2 servo with the model.

On the Dxe to reverse the channel hold both sticks up and in and you will enter program mode and you can use the aileron stick to switch to different channels and push down on the elevator stick to reverse it and the orange light will turn red. Don’t know if it is the same on the new DXS but the transmitters look very similar and I would assume it has the same process

Hey, Brian, awesome video and very thorough as usual. I just maidened this today after shakedown flight. She was flying and landing a bit hot, so I moved the battery 7/16" back from front of compartment. Now she really flys slow and super smooth IMO. *Question: Do you think if I set up full flaps at 1/2 of normal, and landing flaps at 1/2 of normal, this might smooth the flaps flying with DXS and no down elevator compensation?

I've done the same upgrade on My Carbon Cub S. An easy solution is upon start up when the Plane is zeroing itself and looking for Bind, have the tail elevated about 3". It fools SAFE mode into thinking its on flat ground and when it is pitched forward about 10 degrees. Now the extra lift wont balloon you by pitching back, it'll keep itself level.

HI Brian thank you for your videos really helpfull,I m a newbie in the hobby flying a UMX turbo timber and love it, I m looking to get the Carbon cub s 2 without the gps module (I like to get lost), I have a Spektrum dx6e (6 ch) can I add the flap channel on the radio or I would need a 7 ch radio?

Your innuendo s are priceless

Did you have to programme the servo, or when you install them do they just know what to do? when the switch is used?

Thanks!

Brian what did you mean when you said you would "strip" the landing gear when coming down before the flaps were installed? I find this plane is super bouncey so far without flaps, it rarely tracks straight down the runway and wants to get squirly

Hi Brian. Thank you for this video. I have ordered my Carbon Cup together with the flaps extension. Just a curious question.....have you ever flown this (together with flaps) with the floats? If yes, how is the "feeling"? Is this still ok?

Yay now I don’t have to spend 300 dollars on a better transmitter just to put flaps on my cub! Thanks for the great video!

Hey Brian have you seen the Habu trainer jet RTF Looks pretty cool I seen it on RC Sailers channel Great video as always ✌️ Im with camera crew I'm not a expert but the flaps look to be working fine with that controller 😁

YES!!!!! The dxs works with flaps! I don't have to buy a $350 transmitter. Yay!

I had the red version of this plane. But sold it. Taken off was always tricky was all over the place . lol how does the ground handling compare to the turbo timber?

Good Videographer!

I ordered my second Carbon cub from your site. I had my first one fly too high on beginner mode and lost orientation. Super bummed. I'm planning on doing flaps this time. Will that help keep it from climbing to high? I'm planning to practice using down elevator on this one also. Thanks for the tips. Really helpful to beginners like me.

After playing around quite bit with the new-to-me NX8 I decided to try some mixing on this airplane. I mixed throttle/pitch, flaps/pitch (needed 2 mixes, one for takeoff and one for landing flaps), aileron/rudder and aileron/elevator. I also moved the servo elevator control rod out to the last hole to increase elevator throw. Then I added 30% elevator expo. it takes some playing with rates to get everything balanced, but it's made a huge difference in experienced mode. I'll never fly it again with the DX-S that came with the airplane. I may make a video with all the settings details!

Yes Brian You're CRAZY..... LoL but you're still a decent Pilot

Thank you for the video, could you recommend an entry level transmitter that would have mixing. I am kinda new to flying, I have the mini apprentice S and this plane (and now with flaps). I usually fly in beginner mode or sometimes intermediate but scared to try the flaps in those modes for fear of not having enough elevator authority LOL. Thanks again !!

I have one of these. Purchased the float kit too. After some experience with the stock plane I’ll add flaps and the floats. With floats the flaps will be very helpful as it will shorten takeoff and landing considerably, as it does in my 185 aircraft. Although I have no experience with flaps on this model, I can offer some insight from lots of experience with full sized aircraft. Take off: Almost never take off with full flaps. Full flaps are a drag machine intended to kill forward momentum. I never use full flaps on takeoff from grass or pavement. Half flaps are also sometimes labeled takeoff flaps for that reason. On water, with floats, full flaps are used because the extra lift helps lighten the aircraft and break surface tension. Once flying and at an altitude of 10 feet or so flaps are slowly reduced so that the aircraft can speed up in ground effect before attempting to climb. So why not climb on full flaps? Because the drag of full flaps the plane will slow down dramatically if the engine quits, and it will not glide engine out except at a very high rate of sink. So one of two things will happen after a low altitude engine failure. The pilot will either fail to react with lightning quick reflexes and the plane will enter a low level stall / spin, and that is deadly. Nobody ever survives a stall/spin. OR, the pilot will react and get the nose down but the rate of sink will be so high that the landing on water will be destructive. The plane will flip over with you inside and probably unconscious. That is why full flaps are not deployed except during landing (and operations) when the landing is assured and with sufficient airspeed. And as mentioned during water takeoff. What has this got to do with model aircraft? It provides some perspective of exactly what flaps do and when and why they are deployed. My plan is to get the plane at altitude and do lots of experimentation with flaps before attempting to take off or land. I’m expecting the flaps to accelerate the stall and make recovery more difficult. I also expect to need more up elevator to counter the effect of the drag; and more power too! Thanks for the long and detailed explanation. Sure beats the job Horizon did.

Would be interesting to see you bind this up to the DX18 and see if you could optimize some of the flight characteristics. I'm curious if this plane is good for more than a beginner if you say love the Cub look but don't want a big one. I think I'm interested, and like you, I would avoid the GPS and landing sensor.

Brian you will have better control with your DX18. I wanted to see if you had trouble like I did getting it working. It wasn’t hard just a pain because the GPS takes up 3 channels on the older version of the plane. I had to unplug the GPS and turn off the panic button in the channel assign menu and move things around to get Aux 2 to show Flaps on my DX9. Still works without doing all that but I just wanted all my flap settings in one place.

We need a second thoughts video with programmable TX flaps setup 😁

Where do you get larger scale Planes like the Boeing behind you ?

Forgive me for being new and not knowing the verbiage, but what is the part called that links the servo to the rods. I cant find the part. Thanks in advance!

Question on the flap install would it been better to use a digital servo or the one you used is ok ?

Thanks for the great, detailed video. I'm in the process of putting flaps on my RTF CC. I have the servo plugged into output 8 on the receiver and I'm noting that with the orientation of the servo its positions need to be reversed if I want switch D positions 0/1/2 to result in raised/half/full flaps. I'm using a DXS, but I have a DX6 on the way. Should I reprogram the the flight controller (A3230A) to reverse output 8? Is the A3230A even re-programmable? I installed the Spektrum Programmer app and plugged the controller in via USB, but the app doesn't connect. I assume when I have the DX6 I can invert whatever switch I assign to flaps - I just a) want to make it consistent between transmitters, and b) learn and understand what I'm doing. Thanks! (P.S. I'm starting to think the A3230A isn't reconfigurable in anyway, so it's on the TX side where changes would need to happen. Right? )

Did you mix in any down elevator. On half and full flap settings the plane balloons like crazy and will pitch up to the point where I have to give full down elevator to keep the nose down if I give it any throttle

I have a DX6e transmitter and horizon hobby says that you need 7 channels, but is there any work around that I could possibly do to make this work? Or is there a way to conect something else in addition to the transmitter to just control the flaps?

Brian, I installed the flap servo and connected it to ch8 in the flight controller, the flaps work in all flight modes using the DXs transmitter that came with my RTF kit, also the plane flies more like it should when the flaps are set to the factory settings, it won't "Balloon" out of control like yours does, instead they don't slow the plane down near as much and add more lift so you can back off the throttle to slow the plane for a more controlled landing. Your prop balancing method leaves some margin for error, you should use a balance tool and do it correctly.

Hey Brian wat made the Cub stall twice like that I seen in the video?

Did you have to use a different receiver too?

The flaps on mine made it climb almost vertical....i have now mixed in 20% and 30% down elevator ..with the flaps....

Hi Brian, Will the flaps work with the RTF DXs transmitter if a GPS module is installed?

Hello Brian. I’m working on a project, and my issue is the servos and motor jitters when I plug in the 2s lipo. I changed esc and still the problem. Changed servos and it was a little better but still there. Would you might have some idea the cause or fix?

Can you explain more about balancing the prop? How did you know something was wrong? What causes it? Thanks
