OMG!! You JUST saved my sanity!! I have been trying to set this up on a boat (I know, don't bash me) and I have been PULLING MY HAIR OUT!! I knew it was possible because I have seen it done! THANK YOU for posting this video!!!
I tried this on the DX8 WORKED GREAT!!!! however I learned you can't do throttle cut! this was THE CLEAREST EXPLAINATION I HAVE EVER HEARD. THANK YOU SO MUCH SIR! Keep doing great videos!!
Steve I hope you can help me. I just setup differential thrush and have the same problem with throttle cut with Aux 1. It works just fine with the motor plugged into the throttle on my receiver. How did you get it to work on both motors? George
i've been flying rc's for about 9 years and never needed differential thrust. I've got a build going on right now that has twin motors....needing differential thrust. Although I have a Gen 1 DX8, I was able to follow your video, step by step, and I now have differential thrust working. Awesome! Thanks for your video!!!
I just used this video to set up my hobbyking Lancaster (recently built a spare that I have had for years in the basement). I usually struggle with programming, thank you for making it easy and fun! hope to see more of these tutorials.
Very nicely done. I've watched a bunch of how to's on Tx setups and they are always hard to follow but your's was very clear . In addition this is exactly what I wanted to learn.
From the AMA Feb 2021 edition of the Model Aviation magazine, I've started the build of the model on the cover. It's called the Yin-Yang and your video is nothing short of awesome, and because the model doesn't have any rudder control, (it's solid), your video will help me with my dual motor, (one a pusher, the other a puller or tractor as you call it), differential thrust setup. You have helped me more that I can say and I thank you for taking the time to create one of the greatest and easy to follow videos, that I have ever viewed. Again, thanks for eliminating one giant headache for me and at the ripe old age of 82, (just had my birthday in January), the fewer problems I have to solve, the more time I have to enjoy my Golden Years and the RC hobby that I entered into about 6 years ago. THANKS! THANKS! THANKS!
This is exactly what I was looking for. I am about to begin a Grumman Goose build and I definitely would like to have differential thrust with this plane for control while it's on the water. Thanks for this perfect explanation and setup.
Chris, thanks for this video. I've accomplished Differential Thrust previously but it was UGLY. I just took my G44 Widgeon (twin engine seaplane) and bound to this...wham bam perfect.
Great job Chris! Damn I would have never figured this out. I have a new Avios Albatross and need to set this up on my DX9 so I can water taxi without having a physical rudder in the water. EXCELLENT EXPLANATION. Subscribed!!!
Just picked up an Albatross, too! Bitchin' plane and my first twin and of course...needing differential as well! What rx did you use. I have a new 637T or a 9350 I can tear out of my big Carbon Cub. Trying to get my head around what I won't have if I use the 6 channel 637T.
Every time I set up a new dual motor toy, I rewatch this video haha probably done it a dozen times now but I can never remember it all. Thanks man! Great video
I have the new DX8G2 and follow ya because there are NO VIDEOS for the DX8G2...GRRRRR so I'm writing to send you a HUGE THANK YOU because I tried following Josh from Flite Test and he has you putting the leads in port 5&6 and using a curve plus he was using a totally different TX. So again thank you so kindly Sir!!
It's an 11 year old foam semi scale kit which was designed for 400 size brushed motors and nicad batteries. My idea was to tart it up a little and over the years I have almost rebuilt the entire airframe, adding retracts, using brushless motors/ ESCs and lipos. as a result it has taken me too much time so far and I have decided that it needs to earn it's keep! Originally the rudders were to be fixed and I had plans to activate them, but the servos and linkages were going to add some unwanted weight at the wrong end of the airframe, so your info should allow me to gain some yaw control. I have connected the tail wheel to the rudder channel and now have the option of adding differential thrust for accurate ground handling/ taxiing. Thanks again.
Thank you so much for posting this tutorial I would have struggled by myself. Nice Guinea pig by the way. I am making a FT Master series p-38 and want rudder authority.
I know it's an older post,but Thank-you.I have a DX8G2 that this will work on. Got the basics,but the mixes and channel assign are a bit of a black art to me.Much easier to see than read about it.
U R Awesome! Thank you very much! U saved me hours of frustration with this most excellent video. If U are not a teacher or professor you have another calling. My FT Guinea Pig will make its 1st flite WITH differential thrust and rates of +/- 125%. I cannot wait! The Spektrum DX9 Manual was of no help. U made it so easy. Thank you, again!
Wow... I can't thank you enough for this clear, concise lesson! You just save me a whole lot of frustration and confusion (LOL, apparently at the cost of a a whole lot of frustration and confusion on your part!
So regular throttle is just both engines. Thats pretty awesome! Anyone that builds their own plane can use that. If you buy a twin engine plane, chances are, it already has a set up in the esc for thrust vectoring. If something happened and you needed to replace the electronics, this would be a great way to set up all new electronics in an older plane that has been sitting that you wanted to upgrade.
As many have said, great tutorial on setting up differential thrust. I have an HU-16 Albatross, where both differential and reverse thrust would be interesting. I've learned a great deal about the DX6 transmitter, but I'm not sure how to reverse both motors with the flip of a switch and retain differential thrust as well.
Thanks! One thing to note, if you are using this configuration with a DX6e, don't use the Flap system. The flaps use Aux1 and you can't select it in the Input Config screen.
Roger Banks how do I make differential thrust work on the dx6e then? I’ve spent around 2ish hours searching for something but I simply just give up, do you have any idea?
Thanks for the help! I am planning on building the FT guinea pig and wanted to know how so set up differential thrust before I went and bought the electronics.
Thank you so much Chris. Just excellent. My Flight Test Kraken is almost ready thanks to you. One note. My DX6 did not have and Aux channel as changeable. Figured out that the FLAPS channel is the same thing. If anyone is having difficulties because they can't use the aux, just substitute the word FLAP for Aux and you should be fine. I think it is a firmware change since Chris created this video?
I am building an RC boat with 2 EDF motors, it's a big boat... I found your explanation very clear and effective and to the point. I followed all of your steps and even made a cheat sheet for myself on how to do it again if I need to. I have one question, that I haven't figured out. Since one motor is connected to the throttle input on the receiver, and the other motor to the Aux1, so when i do "throttle cut" on my DX6, only the motor that is connected to the throttle input gets cut, the other motor still gets power. How can i program another switch to cut that motor that is attached to the Aux1 input on the receiver?
3:50 is sOOooo my favorite part of this video because I say the same thing all the time haha THANK YOU FOR THIS VIDEO!!! "oh its beautiful! that took me so long to figure out because I'm not very smart" haha love it so much I dont know how to put my emotions into a yt comment
+Chris Stolle I took it a step further bc I noticed that throttle cut only killed one motor. I can now kill either motor, or both allowing me single engine taxi. I'll do a video reply later.
Not sure if you're still out there, but following your tutorial my motors are opposite of what you say I need. Left rudder gives me left motor power. Same for the right. Any suggestions would be greatly appreciated 🙂
Chris, just what I was looking for for a water rescue vessel!! Turns with differential thrust! Using a Gen 1 DX18. Now, how do I hook up a third brushless motor for a third motor to give me reverse capabilities(actually a forward thrust motor mounted backwards and will not engage until I flip a switch that turns off the differential motors and only turns on the reverse facing motor? Make sense? So far the water rescue craft works really well! Thanks, John
Nice. I may try the throttle instead of the mixing. I do want channel 6 to be higher though. Ch 6 will be an additional EDF that will be running even when the pusher prop is off and folded back. I need extra umph for a heavy load.
Nice. Tied it in. Lowered the travel on Aux1. As I rolled lower than 99 the EDF sped up even with the throttle was off. Then as I hit the throttle it sped up as well. I suppose I could run EDF only and at full throttle either by rolling travel even lower or throttle cut. I would like my throttle to be that roller full time and my pan and tilt to be the left stick.
Great Video- Just set up my Guinea Pig by your Info BUT if I use Switch C for throttle cut it will only cut one engine- Guess you have to do something special to get a 2 engine throttle Cut? Great Job Again!!!
Great tutorial. Very clear and easy to follow. Thanks. My question is this....I have an HU16 Albatross twin and it can reverse by switching my gear switch. Will your differential setup work with my setup? I want the differential to help turn the plane when taxiing only. The water rudder is very inefficient in anything over a 3 mph breeze. Thanks!!
