I got the bounce ironed out by simply shifting my CG back from the first strap like you did. Let me say you are probably one of the best reviewers out there. You go over throughly the CG’s you have figured out and that helps the rest of us tremendously. Your very honest with what you are encountering in your flights which helps the rest of us cut down on surprises. Thank you and keep up the excellent work, your reviews have guided my last three plane purchases and your videos have helped me to iron out minor issues. Thank you for your time to make the videos and helping those of us who are working to become better pilots.
Thank you so much for your kind feedback! Glad you got the bouncing sorted. The model lands very nicely, but can get pretty heavy on the elevator in the flare of the cg is too far forward.
Hi Sherman. "Bounce"? Yikes! I have not flown my new Viper 90mm yet, (super nervous to try) and I was unaware this was a problem with this model. My Cirrus is like that - and it makes me crazy! Are you actually flying slightly tail-heavy then? I appreciate the heads-up, this kind of info is so helpful. Thank you! Dale
The 70mm version is a great jet, a perfect all-around performer & it gets good flight times. I own a few foamies, of course I prefer the look of my wood/fiber glass models, but I for one actually like the bare foam over white paint.
First impressions are strong impressions: You are very professional, organized, knowledgeable, put primarily as an instructor and teacher, you have all the qualities of a great presenter and none of the annoying and scatterbrained traits that a few of the other RU-vid artists have. Did I mention you are a great pilot. You don't overtalk the flight which is distracting from listening to the beautiful sound of this great jet. Thanks so much for just that big Plus! Such a relief to listen to your explanations and tips. This is my next plane. Just bought the Habu SS and I am ready. Can I order through your link so you get some type of benefit from my order? Thanks and thanks and thanks!
@@Thercgeek You're welcome. Got mine Friday, she's all put together, balances great 15mm back from the plastic. I set the throws from this vid so the maiden tomorrow is on you. Ha! If you don't mind me asking, any coupling issues in knife edge? Just wanna know if I should mix in any aileron or elevator to the rudder. Cheers!
Glad to report Horizon did the right thing and replaced the Viper 90mm. I sent the plane back and I guess they saw the problem. I think it was some of the wood on the esc tray was not punch out completely and was sucked into the fan. I have been a customer of Horizon for many years and have always known them to stand behind there products. They are a great company. I tested the plane on the ground and ran a few batteries through it. Looking forward to the maiden. ✈️✈️✈️
Thanks again for sharing your knowledge, for the great video and answering my other question. In the end I bought the Viper 90. Beautiful model and sturdy landing gear that also works well on low grass. However it has a problem mainly in landing and full flap: the left wing stalls close to the ground. It happened to me twice and I gave up, temporarily. I saw online that using the "Crow" system seems to land much better. I would be grateful if you could give me some advice. Greetings again from Italy.
Could you also tell me why you do your CG checks with the plane upright? I always thought a low winged plane should be upside down on checking CG? Thanks
Whether right side up or upside down, it doesn’t matter when checking the cg. Typically it’s just easier to check a low wing airplane upside down because it hangs a little easier. But, it’s not a requirement. I switch back and forth depending on the airplane and what’s easier.
My compliments for the amazing video. I felt like buying it. I have a fair amount of experience with airplanes and a lot with helicopters. Before buying it I would like to ask you if the landing gear is also good on a grass runway or if there are any problems, or if you have tested it on a grass runway. Thanks and greetings from Italy.
The landing gear are quite robust in the model actually. I think it’ll handle grass without too much trouble so long as it’s decently mowed and not super thick fescue.
Does the BNF version allow forward programming to change AS3X and SAFE gains as you would with say an AR631 that you'd use with the PNP version? Thanks
You can get into the forward programming, but unfortunately the bnf receivers are locked. So can’t adjust gains out of the box. The receiver can be unlocked, but I think it requires connecting to a computer to do that.
My friend, you've been involved in EPO much longer than I have, so I'm surprised you don't know this. Expanded Poly Olefin plastics exude plasticizers over their half lives ( about 10 years). These vaporous solvents will cause polymer enamel AND water soluble white paints to yellow out HORRIBLY at at frightening rates. Use a thinned (oil base) UV filtered polyurethane, or UV stable acrylic polymer art sealant ( test an area that isn't structural or cosmetic for compatible traits), and just mask and coat your EPP. Painted areas? Mask, or cover. You' re better off letting the foam discolor a little unless the extra weight and shorter flights don't matter. Me? I armor these $5.00 foamboard EDFs to the teeth. So, five dollars in materials. ( Motors, ESCs, Rx, servos, etc. salvageable). I digress. Applying two coats of clear polyurethane varnish to foamboard results in over a 325% increase in rigidity at a cost of 14 milligrams per 100 cm squared. Pre-coated foamboard and new practices? (FliteTest!) And who knows what we can come up with! Dig what you're doinn' Mike.
Mine took off and lost thrust. After about 35 40 seconds stalled and crashed. Fuselage was destroyed. Turns out the EDF exploded all the blades were gone right down the the route. Sent it back to horizon hoping they make good on the plane. This was the maiden.
great review. I just bought the ARF version of this plane , what is the best Esc,motor and edf unit upgrade for this jet ? for more speed and acceleration ? on 6s.
Hello again Chris. I have been frequently referring to your videos in an effort to get smarter with my RC planes. I was wondering if you would be so kind as to point me in the right direction to find the factory as3x gyro settings that come in the various bnf Efite planes? I always update the receivers to "Open-Stock" because I do not like some of the proprietary mixes, SAFE select settings etc. I do like the actual gyro gains that come in most HH planes. Once the receiver is "Open-Stock" I am only guessing at the gain range HH used for the various planes, and I am having a tough time finding the sweet spot on the gains. As you know, these bnf receivers are initially locked, and you cannot see the actual gain settings in Forward Programming. If you happen to know where I could find these numbers, I would be very grateful! Thank you. Dale
Instead of going to the fwd programming, if you scroll over to the right from the main screen, I believe that it shows you the gains that are programmed. That’s what I did when I reconfigured the eflite f16 with flaperons and tailerons.
@@Thercgeek Thank you so much for the reply. Like an idiot, I did not check the factory gyro settings before I upgraded the receiver. I don't suppose you have any idea where HH set the AS3X gyro gains? Love your videos! Thank you again.
Hi Chris! thanx for the video. Just got mine and I wander for how long you could fly the Viper with the 7000mah battery? I think your fly demo was edited so I am not sure if was only 4 minutes.
Hello sir, I scrolled the wheel on my NX10 but it will not take me to that screen to set up for the thrust reverse. Do I have to update the firmware of the Tx to 3.06 firmware? Thank you!
Well that's timely, I was just looking at this plane. How would you compare it to the Freewing Avanti? Is it different enough to justify having both? I take the Freewing Avanti pretty much every weekend. I have a few 105mm-120mm EDFs, but those don't really make for a low-effort relaxing outing. I wouldn't mind having another "everyday" type EDF.
Honestly, I’ve never flown the avanti, so I can’t say definitively how different it is. That said, as an everyday edf this definitely fits the bill. It is bigger than the avanti which is nice and being able to fly the large packs gives some nice flight times.
Hey man I’m really stuck 🤣 do I need a 10ch spektrum radio to have ch7 for safe mode , ch8 for reverse thrust , & 9/10ch for pan&tilt kit like the motionsic bag. Thanks!😁😁
Unfortunately, it’s a discontinued great planes tool. I’m trying to source something similar to be able to offer in the future. Haven’t had much luck this far. 😕
Donald L, Motion RC has a benchcraft deflection meter that's very similar. They came back in stock about 2 weeks ago. Not sure they are still in stock.
Hi Chris, I have some e-flight Jets with Spectrum ESC and Spektrum iX20 radio. Trust reverse works great at all. BUT for now I want the 90mm EDF VIPER fly with another radio make (CORE from Powerboat-Systems). DO YOU KNOW if it is possible to use the trust reverse feature also with another radio like Spektrum??? BTW: Maybe you remember me, I am Thomas from Germany and I order all my afterburners at you 🤣
Make it into an 8-channel crow setup like I did and you can sustain a flare for landing: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ly7y2UUB7Rc.html You can also high alpha with about a 25% crow mix. If you're flying stock, it'll most definitely tip stall with flare attempts instead of settling in, and high alpha is basically out of the question.
You know, from what I’ve been seeing recently, they’re a pretty good value. Seems they’ve got a few things in the works right now, so I’m eager to see what they come up with.
It’s called an accuthrow meter and was made by great planes. Unfortunately, it’s no longer made. I’ve been trying to source getting them made so that I could offer them, but no luck so far. 😕
