- The folks at @TheRcSaylors had something similar happen and I had to play off the title. 😀 In this video you'll see me showing you how to perform high alpha passes in the Viper 90mm by @horizonhobby - and how to avoid crashing like I did, though damage was truly minimal. It's already repaired and repainted on the belly. The jet is more than capable of doing it once you've set it up correctly. Proper setup can be achieved by following my guide: • E-Flite Viper 90mm Max...
Hope you enjoy! More alpha footage coming soon - for now, I'll show you how to do it before I show how many times in a row I can keep it going.

Such an epic video. Keep pushing the limits!
Will do, sir!
Loveeee the viper content followed by the f22 😁...Another sick vid bro
I love aviation too! Loving the videos 💯🔥🔥🔥🔥🔥🔥🔥🔥🔥
Awesome! Thank you! Super glad to have you onboard dude.
Way to push the limits!!
Perfect way to explain the anxiety that comes along with trying new moves.
I use it to fuel me😎
Everything can be explained using aerodynamics if you're brave enough.
@@TwoBrosRC
& Gravity 😁
This is what I'm looking to learn.. Thanks jon
Glad to hear it!
Wow that was awesome. Great piloting!
Thanks Michael!
Woah that’s totally awesome. Not quite there yet but I wannabe. Thanks for sharing
You can do it bud - just follow the hand movements and use my setup guide linked in the description. I'm brutally honest with people - if I can do this, you can do it too.
Jon:
U gotta get the new umx pitts! Idk if ive ever had as much fun, with my clothes on, flying that lil aerobatic hellion! 7 minutes near 3d-ish flights! (With safe/as3x OFF & some radio tuning.) Hopefully video will b up today of our Saturday flying. (One way rc). See all kinds of vids on it but ppl just poking around.
So cool
No, U!
That's rad! I have the smaller blue viper, I'll give this a shot next time, but I dunno if it has enough thrust. Do you have the make the transition to high alpha so high? Can you make the transition at a constant altitude? Do you have AS3X active in the plane? I saw it do the little start-up dance. Subbed!
I could make the transition at a lower altitude. I prefer doing it higher up to have enough time to throttle up and get out of an asymmetric stall. It doesn't take much to get this jet to spiral to the ground. The 70's stall characteristics are even more severe. The setup I'm flying on is found via czcams.com/video/uUOJhLrSibw/video.html
AS3X is active but it's throttle-based. The vid covers it. Thanks for checking out the channel!
Hey Jon, How do I get Crow Setting in my new Eflite 90mm BNP Viper Jet. Can it be done with the AR367TA receiver ?
Or do I need a 8 channel receiver ??
You'll need an 8ch receiver to do it. My guide covers this for you: czcams.com/video/uUOJhLrSibw/video.html
Hey Jon , How do you get your anti collision lights to blink twice or three times ??? I bought the Freewing LED light controller V3 $9.99 from Motion Rc. When I plug in the controller I Just get one single blink ??? Not very bright ??? Did I buy the wrong blue light controller ???
We use the Freewing multi-function control box to control the lights - not the LED Light Controller v3.
Amazing flying as always. Do you think you'll get the Freewing Mig 21? Would really like to see what you can do with one of those.
No idea, probably not anytime soon.
Jon, you every add this same Viper configuration to the 70mm version? Curious, if this works for the smaller plane...
Hangar 18 Hobbies is getting me a Viper 70 on demo credit. I'll be setting it up this way again. I've done it in the past - one of my oldest RC uploads was a crappily-produced Viper 70 crow/full span flaps mixing demo you can see if you look back far enough. I'll be trying this same stuff with it. :D
Nice vid dude! Like what you said about pushing through...so many folks have issues with that. Gotta push always to get better. Heck I crashed my F-16 today pushing it doing formation high alpha with a buddy...I had help he he...we got close...REAL close. It will make for an interesting episode I guess! That wasn't a crash landing by the way...you were just to lazy to put the gear down first...it happens!😁 Good stuff!
Haha, thanks dude! Really all that limits us in flight is our skill and that's always improved by pushing harder. Just like working out, you build those connections in your brain to fly better once you keep trying and stop giving up at the first sign of distress.
Crashing ALWAYS happens. Granted, if ur on a budget, fly how you are comfortable. Gotta override ur brain saying 'dont do that, that will make you crash'!
Very cool! I bet you could do this with the Freewing Avanti S.
I do need to pick up an 80mm ARF soon... Ideas to consider!
That's not a crash! :) that's a perfect belly-landing. My belly landings are nowhere as good as that lol
Haha, well, that's one way to look at it for sure.
Perfect tutorial bud’ 🥰 beautiful concrete kiss too😂🙈
But you really should buy the Freewing Mirage 2000 80mm HP…like really 🥰
It's on my list of birds to check out this year. Thanks Arthur!
@@TwoBrosRC you’re more than welcome 🤗😇
Question do the two "ventral fins" have a real functionality to them or are they only for looks? I personally would leave them off, it looks sleeker, like a FUTURA.
The fins work as lateral stability devices.
Wicked flying! Curious what transmitter settings you use such as expo, duel rates or any other tips and or tricks.
Thanks Todd! The setup I fly is here: czcams.com/video/uUOJhLrSibw/video.html - I go over everything including the mixes used to perform this kind of maneuver.
Tips and tricks: get plenty of practice😝😝
@@johnthomas1348 That too, of course. ;)
qwhere can i find your tutorial on the transmitter setup for crow {how too!}
ps. your correct in saying people are very interested IN THIS SETUP ON THE VIPER 90! THANK YOU
czcams.com/video/uUOJhLrSibw/video.html - there's the setup!
i bought this jet and loved it.... and then bought the same model but with the FMS badge (fms builds it for eflite) and not only its EXACTLY the same airplane (different colors) i also saved over$300 dollars because it doesnt come with rx. I still fly both and love them. the fms is easier to see in the air
You must live near China for the FMS version to be less expensive. Shipping to the US is at least $150 which makes the jet cost about $800ish here.
@@TwoBrosRC Not really, I live in Ontario and got the E-Flite for USD$850 the FMS was around USD$600. THEN in January moved to Mexico for winter months and got another one sent here for usd$580 from aliexpress.
Does that thing have thrust reverse?
It does!
Did you make it right on the CG, or is it nose heavy or tail?
It's about mid-way through the wing.
👍👍
As I mentioned in your trailer, what UP pitch limit are you setting in Forward Programming to achieve that AoA. I can see that you are probably not using heading hold but I suspect if you did you would get a more stable direction because the rudder would also be inputting. It is a good demo of how Spektrum's technology can help one get extreme flight out of an aircraft. After all the full scale modern jet can't do that without computers assisting the pilot and ensuring max AoA for speed/thrust is not exceeded. Its a shame how there is a segment of our hobby who decry Spektrum's contribution.
No limit - I'm flying manual with AS3X gains tuned based on throttle input. The setup guide will go over everything I use: czcams.com/video/uUOJhLrSibw/video.html
Very little of this is related to Spektrum tech - it's all aerodynamic understanding and enough T/W ratio to fly on the duct once the wings are post-stall.
@@TwoBrosRC My comment was based on you appearing to be holding full aft stick throughout the pass. The jet is not stalled so I assume it is your elevator/flap/aileron mix coupled with AS3X stabilisation which is allowing this. That the balance between elevator and the other surfaces is stopping the AoA from passing the stall point. If the wing stalled, aileron input would exacerbate the roll so AS3X won't help once the wing stalls. Use of power I suppose balances this delicate pitch attitude in that it reduces the aerodynamic load on the wing thus the stall point. Well done. I look forward to trying it on my F22 once I've found the time to finish installing the Thrust Vectoring modification - too many other distractions at the moment!
Oh it's absolutely stalled, Tommy. 100%. It's flying at about 12 to 18 MPH when it's in those alpha passes. Nominal stall speed for a Viper is about 28 MPH without crow and about 24 MPH with crow. It's flying nearly 10 MPH under its stall speed which is a huge difference. The only thing keeping it in the air is the copious thrust to weight ratio of the 3670-1950kv motor. It's entirely flying post-stall - it's ridiculous to behold in person. Getting it OUT of the post-stall condition is the tricky part - you have to let the nose down gently as you throttle up to full, otherwise one of the wings will drop as elevator input is being reduced and it'll spiral into the ground if you overcorrect.
@@TwoBrosRC I'm not an aerodynamic physicist but I have flown professionally for >40yrs and I think the thrust to weight ratio is effectively reducing the stall speed. You haven't reached the hovering mode and the wings are still providing control which they wouldn't if the airflow had become detached. It would be interesting to put it in a wind tunnel with some smoke. The thrust is effectively reducing the aircraft weight so much that the airflow does not break away. Perhaps there is a Professor in aerodynamics out there who will correct me - I'm usually wrong. But I've spent a career of pushing the limits in full scale aircraft and have to admit to having got it wrong occasionally and smashed up both aeroplanes and helicopters but never hurt anyone - much!
@@tabdycollins I chatted with @TailHeavyProductions about this earlier and I think you're both right - it's not quite stalled, but my money is on it being very close to it. The crow makes such a huge difference in this jet - there's no way to perform these alpha passes without it.
Did you lose the stabilization finns?
Yep. Months ago. Had a tail strike and damaged one of the fin connectors. Glued it back and it flew off mid-flight. Still waiting on backordered parts.
Yup, I have had three non existent tip stalls to date.
They're definitely not "tip" stalls, it's just one wing stalling before the other. Asymmetric stall. ;)
Hahha! I get the title
do that harrier with your jet on the grass, less risk for the plane in case of fail
Already did, but it's less impressive.
For safety sake do it with the gear down!?
Gear down causes unsustainable drag. I can't fly it in high alpha with the gear out. Tried it already.
@@TwoBrosRC Ahh Haaa, OK. Great flying!
