[@roberthill2315]

Thanks! I've watched every video you made for the planes I own, and they have helped tremendously. I recently purchased an FMS Viper 70mm V2, because I believe it will help me tune my skills for the Freewing F15, and Freewing F16 Thundebird edition. When I maidened by Viper, I had watched enough to set everything up correctly, however, in light winds, I didn't sufficiently anticipate the plane stalling on a turn. I thought I had enough thrust to get through the turn but did not. I anticipated other factors as the cause (a hot wifi signal interrupting reception, problems with the used receiver I had in the model). Basically it hit the ground and the nose broke off. I've since repaired it, changed and reoriented the receiver, and this time I watched you video that discusses stalling this plane. I was ready in maiden #2 to try again in light wind (

[@TwoBrosRC]

Thanks so much Robert! We really appreciate the super thanks donation. Your experience is precisely why we showed how aircraft stall and how to recover from stalls. The thrust to weight ratio on the Viper 70 (FMS variant) is so high that it's relatively easy to power out of a stall and get airflow over the wings again. It's super common for people to unfortunately stall this jet out and wreck it - and if these videos can help even a small handful of people save money and have more fun flying, then it's worth it for us to continue producing them.

[@ficosk8]

The stall talk is really useful!! :D

Yep! Which is why we want to see everyone succeed - some other reviewers will just show you that the plane can fly. What we want to do is show you that it can fly *and* show you that you can fly it without wrecking it too. Because knowledge should be shared, and flight / aerodynamics is hard enough already.

Stalls aren't really modeled well in simulators. They're best experienced IRL.

[@adrsprints]

@TwoBrosRC Thanks for that Info. With regard to your tip, not to bank hard (left for landing in the vid) so as to not to lose airflow, would rudder input help (sort of a semi knife edge)? I'm not sure if I worded that properly, but I hope my question made sense.

This was actually a really helpful video. Basic stuff but I honestly wasn’t that familiar with how a lot of this works because everything I fly is so overpowered. I kinda want the rafale but I think this is a better starting point since my habu probably didn’t teach me much useful stuff… also I think this is the good motor for 8s if I want a little more power.

[@TwoBrosRC]

Surprisingly, it's actually not basic info at all - you'd think so, but a lot of people don't know this. That's why we chose to provide the info on a beginner's jet - so people would know how to avoid these issues to begin with. Thanks for checking it out!

[@garydelrosario7213]

Great video, very helpful for transitioning to edf. How do you reinforce foam hinges? And prevent them from failing. Thanks.

[@TwoBrosRC]

Reinforcing can be done with tape, but a jet like this usually requires removing the control surfaces and reattaching them with nylon steel-pinned hinges.

[@speedteamhpi]

Awesome cant wait for E-flite's V2 version..

[@jayaustin3096]

Another comment, could you do a video on how to condition your planes to fly. You mentioned the foam hinges. I've heard people using foam tac with a cue tip. That would be a great educational video. Thanks.

[@TwoBrosRC]

There was no conditioning here - we simply unboxed it and assembled it.

[@crosswindjones]

This is an excellent, high-quality review! I appreciate your organization and the extra landing discussion. The only additional bullet I would like to see in EVERY review is how it handles on grass ops. Getting that insight in a review is hit or miss with mostly misses. Keep up the quality work!

[@TwoBrosRC]

We don't fly from a location that has grass that's suitable for flying, and Vipers are already well-known for handling grass well. This one should do even better with the shock absorbing landing gear, which should make it a good model for anyone regardless of where they fly.

[@danielfulop3470]

Hello. the Led-afterburner light is a part of the PNP package ("Viper V2 15th") directly from FMS, or was it mounted additionally? thanks for the response, many more similar videos.. daniel, slovakia

Can you tell me what video you were referring to in setting up the AS3X gain to throttle curve for fast and slow flights? Nice flying and landings!

Are the points on your throttle / AS3X gain curve the same as the curve you used in your F-22 setup video? I set my Viper up last night with your recommended gain settings with the gear up and gear down curve from the raptor tutorial.

Yep, they're basically identical.

(planning on getting at least 3 batteries) and second question what is the connector that i need for the battery is xt60? i hope so. thanks in advance

3600 HV packs weigh about as much as 3300 LiPo packs. 3300 should work fine. The ESC uses XT90/EC5.

[@TwoBrosRC]

Absolutely it's worth doing.

[@JohnDoe50047]

Hi, can you translate your flap settings into EdgeTX's servo travel scale? Rather than using percentages like Spektrum, -100 is full deflection in one direction, 0 is centered, and +100 is full deflection in the other direction. If -100 is flaps up and +100 is flaps down, where would your settings be? Or alternatively, what are your settings in millimeters of travel? Thanks!

[@TwoBrosRC]

We use -150 and +150 units of travel.

[@stainjah]

Is it best to put in a spektrum reciever or v Will the reflex gyro v2 work just as well with my NX10?

[@TwoBrosRC]

It doesn't come with a Reflex gyro, but Spektrum receivers will work with one if you'd prefer to use it.

[@toddflyer]

I really value your opinion. With EDF jets, what are the best jets for medium grass ops. From your experience can you list the best down to the worst EDF jets that can perform on grass. I currently have the Eflite f 15 hand toss no problem. I also have E flite 70mm Thunderbird. It won't budge on grass. Thanks.

[@TwoBrosRC]

We'd highly recommend finding pavement or smooth dirt to fly from. Grass is terrible for many reasons, most of which relate to the amount of stress that the uneven surface causes to aircraft gear and the mounts that hold them in place. There is no perfect grass jet - the only thing that's come close for us to being usable on grass is the Viper 70mm and Viper 90mm.

[@toddflyer]

@@TwoBrosRC Ok. I thank you for the advice. I agree. Grass is terrible for many EDF jets.

[@flanker-zy18]

Very detailed explanations! In your opinion, is the 70mm f16 more forgiving to fly for a beginner?

[@TwoBrosRC]

It definitely is, but it won't teach you how to avoid stalls. This is why it's not our go-to recommendation if someone is interested in building necessary skills in the hobby.

[@flanker-zy18]

@Two Brothers Radio Control ok 😊!

[@ImCxlt]

I am looking at getting this model however I have a Budget. would an AR620 be a decent/good receiver for this plane?

[@TwoBrosRC]

We'd recommend saving up for an AR631 at minimum - you'll want to put an antenna away from the wiring and battery. It might work but we would not recommend that setup.

[@MayBayRCWorld]

Seem you dont need to turn on flap when landing ? did it make easier for landing ?

[@TwoBrosRC]

We're using flaps.

[@thomaseperjesy9171]

Are there any (major) differences between the FMS 70 and the eflite 70 or are they quite the same?

[@TwoBrosRC]

The FMS variant uses a stronger motor and ESC combination, but doesn't come with a receiver.

Hi John -is it’s easier/better to run tyhis off a reflex gyro or a programmable spektrum ar630 as3x reciever combo? The reflex gyro needs an 8 channel reciever.? But with the ar630 i can forward program the gyro on virtual channel > is this correct. ? Cheers - i dream of flying like you !±

[@TwoBrosRC]

We'd recommend an AR631 since it has a lot of wiring and you'll want to position the antenna away from it. This jet doesn't come with Reflex, if memory serves.

[@kianwong4625]

Hi John -wow you are so quick to reply. So if the AR631 has 6 channels( and all the controls are used up ), how is the gyro connected to reciever and hence the transmitter? Does it appear on the TX under forward programming as an aux channel? Thanks so much for your help.@@TwoBrosRC

Hi, thank you for providing the detailed explanation on flying this new Viper from FMS. I have a question regarding to this Viper though. How different is it from the HortizonHobby 70mm Viper? Comparing their physical specs, they look identical. Same length, same wingspan, same lines almost everywhere. The HorizonHobby 70mm Viper, as we know, isn't an real easy model to fly, very easy to bounce and pretty fast speed when landing. Thank you for your answer in advance. Please keep your excellent work which is very helpful!

This is essentially the same jet. This in my opinion is the better viper 70s. This one is closer to the price the jet should be and those aquishy wheels. I don't have the v2. But I have the eflite and the v1.... they are the same jet. Or might as well be. This is the better deal. Imo

[@TwoBrosRC]

Definitely wouldn't recommend it. No idea if it's safe or not, but you'd be missing out on a ton of thrust. Get 6 cell packs if you're planning to fly a 6 cell jet - flying it on underpowered thrust is far more likely to cause a crash.

[@lw216316]

@@TwoBrosRC I hear ya bro but the plane is not for me. I'm an rc instructor. The plane was given to me as a donation for a 15 year old student I am training. He has some 4 cell batteries already but honestly can not afford 6 cell batteries. So I was hoping maybe the plane could run ok on 4 cell for his benefit. Since it is his first jet he would not miss the extra performance of the 6 cell. I had a Motion Rc Rebel 2 70mm that ran on 4 cell. This Viper weighs almost twice as much so I guess a 4 cell would not work. I'll probably give the kid one of my 6 cells.

Vipers dont need any gyros really it's a simple jet but great man

[@TwoBrosRC]

We didn't say it needed one. We said we're using one.

[@DownNDirtyRc]

I need to come up there...do you do lessons?😂 Im down in wilmy

[@TwoBrosRC]

That's a bit of a trip, innit? But we could definitely help you out if you're in the area at some point.

[@DownNDirtyRc]

It's only like 2 hours lol I go up to tower 19. That's where my ultimate came from

[@DownNDirtyRc]

I mean hangar 18 lol

[@user-yg4jr5zx3x]

Say, what’s the difference between the E-flight Viper 70mm and the FMS Viper 70mm v2? Other than the landing gear of course! :)

[@TwoBrosRC]

The landing gear changed from chicken wire to suspension struts, and it received a new paint job. We're also pretty confident that it has reduced stall susceptibility too - not by much, but just enough to be noticeable for us since we've flown four different Viper 70s by this point.

[@dalekelley3003]

You flew the 70mm Blue Angels FMS Viper a few months ago, How would you compare the two. Thanks Jon. I would say you talk too much nit, it's all PACKED with solid information. Keep up the great reviews. Wish someone woul6co.e out with a good Twin Boom Bobcat again, would love to see you fly and review it. ✌️

[@TwoBrosRC]

They're very similar and use the same power system. The V1 stalls easier, though, and is definitely more difficult to fly and land.

[@FlightLogProductions]

The “Blue Angels” esq Viper 70mm is v2 also.. the only difference between the “Standard” V2 Viper 70mm and this 15 year anniversary edition is the paint scheme, Landing gear (this is the huge deal) and the front landing gear cover (moulded differently to allow the new gear). The “standard” Blue Angel esq colored version should not be confused with the “original” Viper 70mm.

[@ToyManFlyer1100]

😂😂😂😂....Barrel Roll on take off....Show-off..!!!😂😂😂

[@altselgreen9115]

Angle of attack is what it’s all about

[@stainjah]

I want this sooo bad. But fms dont ship to Norway :/ is there a way to get it for me?

[@TwoBrosRC]

That's a good question - you'd probably have to try ordering from FairRC.

[@stainjah]

​@@TwoBrosRC nope checked there also.

[@helmuthuneke1775]

AliExpress from China

[@markschools3147]

Would a Admiral carbon 5100 70c be OK for this Jet? Thank you

[@TwoBrosRC]

It probably won't fit unless it's very thin for a 5k pack. We highly recommend SMC 3600 packs, Spektrum 3200 packs, or SMC 4400s or Spektrum 4000s. Anything bigger will make the jet stall easier and fly worse overall.

[@markschools3147]

@@TwoBrosRC Thank you

[@markschools3147]

I purchased the viper from FMS and finished the build. This is my first jet. I use a Futaba 8fg with a fast receiver. I set all the channels and everything appears to be working properly.I bumped the motor rotation is right. The thing is.. I am use to setting the throttle full and plugging in the battery and getting a beep and lowering to zero and getting a beep to let me know I have full range of motion for the throttle.It's not doing that or when I plug the battery in I am not getting the beeps for the cell count. I have all control surfaces working and throttle from zero to full. I'm I missing something? Thanks, Mark

[@TwoBrosRC]

@@markschools3147 The ESC in this Viper may or may not deliver two beeps when you calibrate it. That's totally normal. Not every ESC will do that.

[@markschools3147]

Thank you

[@Papa_Shorty]

Seems a little more advanced than I’d want to start with. Probably should start with something simpler.

[@guilhermegarcia4338]

How much mm has the wingspan ??

[@TwoBrosRC]

1.1m

[@ILAYARAJAraja]

Share the Buying link...

[@TwoBrosRC]

It's in the description.

[@JohnVHRC]

What was the battery levels after the flights??

[@TwoBrosRC]

Storage voltage. 3.8ish.

[@velocistafpv]

I need more space in my house. 😅

[@2whl4re]

Your comments on accelerated stalls are useful, but not entirely correct. An airplane can stall at any airspeed, any attitude. Stall is a function of angle of attack, not airspeed. The wing load factor has a huge impact on stall speed, which is why a stall in a turn or with abrupt control movements (higher load factor) is more likely. At 60 degrees of bank, the load factor increases by 40 percent (and along with it, stall speed). A stall at greater than 1g load is an accelerated stall. Great channel, just found it and enjoying your reviews!

[@TwoBrosRC]

Thanks! We're pretty sure that we covered most of this info in the vid though.

[@f900ex5]

Great video, but the background music is not needed.

[@TwoBrosRC]

While we appreciate the compliment, please don't tell us how to run our channel. The music we use is a stylistic choice that our viewers have come to expect over the years. We're sorry that you don't enjoy it, but it's deliberately chosen for the style of video we shoot and we have no plans to change it.

[@richarddorsch7275]

Very nice plane and instructional video but I see you even you as a skilled pilot have some stable flying and landing issues so I don't see this plane as a beginner jet.

[@TwoBrosRC]

It's a pretty windy day. Watch our recent landing tutorial and you'll see easy it is.

[@tx-zeh4108]

I belive beginner planes should be cheaper. If you are a beginner, no way you spend 500 dollars on a plane

[@TwoBrosRC]

This jet isn't $500.

[@madsimoninsky]

nearly any jet with a gyro is a learner jet

[@TwoBrosRC]

Be sure to tell that to modern fighter pilots.

[@madsimoninsky]

@@TwoBrosRC i love the channel but i do believe .if your using a gyro your not truly in control ,and the best way to advance is to fly gyroless , slope soaring teaches the best to read aircraft control. this only refers to rc planes not real one that fly into trees at air shows and crash

[@maybejoshh1907]

there is clearly a vague understanding of the word "inexpensive" here

[@TwoBrosRC]

$299 for a 70mm jet is inexpensive. There may be a vague understanding on your part of what RC aviation costs.

[@tomg6284]

To fast.

[@TwoBrosRC]

🆗

[@yellowcolorado25]

You're too intense man. Calm down and enjoy the flight.

[@TwoBrosRC]

This is the weirdest critique we've ever gotten. Thanks?

[@stfuliberal]

Would the Habu be in the same class for learning my first jet? Thanks man.

[@TwoBrosRC]

The Habu is more of a training wheels jet. Much easier to fly, but doesn't really teach how jets truly operate. For more, join us on Discord and we can explain more clearly bit.ly/TBRCDiscord
