ICH HAb DIESES modell und kann nur bestätigen es fliegt hervorragend. Ich war selten so überrascht.!!!

@reckemroysrc3764 Год назад

Love my 70mm viper. Definitely need those dubro wheels excellent flying Jon and some greasy landings 👍🏻🤓🤘

@txkflier Год назад

The 70mm FMS T-45 Goshawk was a good one as is the 70mm Freewing BAE Hawk. They won't bite in the air like the Viper, but they are fast. It's a little hard to keep the nose wheel from touching first and starting a series of bounces when they're nose-heavy. I've flown my 70mm Hawk with an HRB 5000mAh-6S, but they fly and land much better with a 3300.

@adamrodgers2377 Год назад

Great video and great flying in that wind.

Great jet! The Eflite 70 mm viper was my 1st jet and after being crashed, repaired, repainted, and rebuilt, it's still a gem. I've moved up to turbines now but I still don't hesitate to pull out the ole viperjet and ring her out! Great review as always, keep 'em coming Jon

@TwoBrosRC Год назад

Will do Richard, thanks! It's definitely a great jet for new pilots.

@ArthurRC Год назад

Very informative video my man! It will help beginners for sure ! Nice job as USUAL 🤙🏻🤙🏻🤩🤩

@TwoBrosRC Год назад

Thanks Arthur!

@jeffhenderson934 Год назад

Ordered this as a Christmas present for a friend who had a first generation Eflite 70mm Viper. (Stuck or failed aileron servo) The dreaded power dive. I like this paint scheme better. FMS makes some good stuff. I had never owned an FMS till this summer. Started with the Yak-130. Then the 80mm Bae Hawk. Quickly became my two favorite jets to fly. Then RU-vid forced me to buy a Futura v3. Without question the best jet on the market at my skill level. Their 1700mm a-10 is built, but our weather has been awful lately. Thank you two for all the informative reviews. And reinforcing my need to land slower.

@RogueRc Год назад

Great video as usual! Love the onscreen gps!

@TwoBrosRC Год назад

The KV rating is higher and it has more copper in it.

@motionsic Год назад

Great review and tips! I’ll add one, reducing the nose gear length by 1/8” (or wheel size) would greatly reduce bounce tendency on landing. Not needed if operating from grass.

@eqrc7587 Год назад

Thanks Brothers !!! I got this jet a couple of years ago and plan on learning how to fly EDFs. I like the blue better then the white one too. And the new tiers are ordered 👍🏻✌🏻🖖🏻

@TwoBrosRC Год назад

Hope you enjoy it!

@reckemroysrc3764 Год назад

EQ ROCKS 👍🏻👍🏻🤓🤘✌️

@jared6072 Год назад

You are totally right about this being a good trainer. It teaches the old school way. You mess up, you get slapped hard on the head, and you learn real quick not to do it again😅. Getting those landing real smooth on the viper made landing my future jets a cake walk.

@TwoBrosRC Год назад

Yep! That's why it's our go-to jet for beginners wanting to get into the hobby.

@aragorn318 Год назад

Yes, I agree about the Dubro wheels. Do you prefer their low-bounce or their super-lite?

@TwoBrosRC Год назад

Low bounce when possible. Super-lite wheels work well too.

@Bengraziano Год назад

I love my 70mm Viper. Great first jet. The landing gear will bend like a bendy straw if you fly it off grass though. I only fly it off pavement now.

@TwoBrosRC Год назад

Absolutely they will. Our days of grass flying jets are generally behind us.

@mickydee6550 Год назад

Thanks for the informative video. I had the E-Flite version and liked it, but the blue, white, gray paint scheme was too difficult to see under cloudy skies. I just ordered this version using your sponsor link. Hopefully, the Blue Angels version will be easier to see!

@TwoBrosRC Год назад

Thanks Micky! We noticed the sale email. Here's hoping you enjoy the Viper!

@mickydee6550 Год назад

Hi. I did the maiden and several more flights on my new FMS Viper 70. It was sweet and the Dubro Low Bounce wheels really helped with the landings. I was using some tired batteries yesterday, but I’ve ordered some SMC 6S 3600 HV batteries to fix that! Do you happen to know if the SMC 6S 4400 HV batteries will fit/balance in the FMS Viper 70? Thanks!

@TwoBrosRC Год назад

They should fit, but your best choice will be the 3600 packs for price point/performance. 4400s should be great too though.

@felixsrcworld5112 Год назад

yeah its true landing this viper 70mm trickie a litte bit.

@koalatails5711 Год назад

It’s a nice jet, but my thinking is it would be a good 2nd EDF. A kind of advanced trainer to hone your skills before flying more expensive models. I looked for more forgiving jet to begin my experience. Getting a feel for the EDF instead of a prop, and using flaps for the 1st time ever was enough.

@TwoBrosRC Год назад

It depends on what your goals are. If you want to dive deep into jets and get a feel for what they're really like, the Viper will teach you quickly. If you want a jet but don't want to risk it as easily, the FMS Rafale 64mm and the E-flite Habu are both solid choices.

Thanks Joe! Hope you enjoy!

@Joe_Zajac Год назад

@@TwoBrosRC Jon, I want to get the 5280 Afterburner but on his site he requires a 6s balance lead. Half of my 6s are Spektrum Smart Gen2 with no balance lead. Do you know how many volts the system needs? I’m guessing he’s using 7.4v (2s) so I should be able to wire that up and just use a 2s to power the AB. Can’t find a spec sheet on the 5289AB so hoping you know. Thanks

@Joe_Zajac Год назад

Just saw a picture of the 6s connector coming off the 5280 controller. Looks like 4s of it is used so I guess a balance lead is the only option. That might explain why the AB is so bright!

@TwoBrosRC Год назад

@@Joe_Zajac fiftytwoeightyrc.com/products/g2-battery-balance-lead-adapter is what you'll need for a G2 battery. We'd personally recommend using SMC packs over Spektrum packs when you get to jets in the 80mm class for performance reasons primarily.

@Joe_Zajac Год назад

@@TwoBrosRC Awesome! Thanks. I’ll get the TrueFire and adapter then.

@Daniel-fz7tk Год назад

Nice Flying, this jet is a beast for the price! Is the afterburner LED stock? Or are they like the flaps you have to buy them seperate? And is it able to be be handlaunched? Thanks!

@TwoBrosRC Год назад

Flaps come stock. The AB is in the description. It's potentially hand launch-able but we'd definitely not recommend it.

@dalekelley3003 Год назад

Would you recommend putting a Gyro in the Roc Hobby/FMS version since the Eflite one comes with one? Thanks!

@TwoBrosRC Год назад

We usually recommend a gyro because small aircraft track better with one, and they're less susceptible to turbulence or shifting winds.

Hi, what size Dubro Low Bounce Wheels are you using in the pier 70MM ? Thanks!

@shanesdiy Год назад

I'd like to know more about that GPS unit and how you did the on screen display? Been looking at various options to track my RC speed and haven't seen this specific one.

@TwoBrosRC Год назад

This is the unit we use: bit.ly/3hDkcsY It has to be plugged into an X-bus port on your receiver, and the receiver must be bound to the transmitter with the GPS plugged into it before it will be read by the transmitter. We use an IX20SE and used an Android screen recorder to capture the telemetry data in real time, then chopped it up and placed it on-screen to add some additional value and info to the vid.

@shanesdiy Год назад

@@TwoBrosRC We do have an AR6610T that should work with that GPS. Will have to just put a camera on the transmitter display though, we have an NX6 and a Radiomaster TX16S to work with so no integral screen recorder for those I am aware of. Thanks for the info, keep up the great work!

We wouldn't recommend either option.

@stainjah Год назад

Hi Jon. I need a reciever for this plane. It is the second version with reflex v2. Will a 6ch spektrum ar620 be enough? I must have a free 3 swich channel for the gyro to be able to select mode or turn it off?

@TwoBrosRC Год назад

Use an AR631 at minimum so you can get rid of the Reflex system and set up your own AS3X rates - also for the antenna being on a lead so it won't lose signal.

@stainjah Год назад

@@TwoBrosRC oh so just rip out the reflex and go full spektrum instead? Must i download the model to the new gyro or must everything be put in manually?

@fa300ry Год назад

Hi Can you tell me if crow works on this plane ? If so what are the throw values/ratios ? I have DX8 radio. Thanks

@TwoBrosRC Год назад

It's not worth setting up on this jet.

@fa300ry Год назад

Honestly, I’m worried about the bouncing , hoped the crow helped by reducing the speed and improved control . Your thoughts

@TwoBrosRC Год назад

@@fa300ry It won't help. The ailerons aren't large enough to produce any noticeable effect on landing speeds or AoA. The bouncing is just part of landing a Viper 70 if you don't have a 100% perfect landing speed and glideslope every time. It handles it fine!

@smiffy788 Год назад

That looks a lot like the old HobbyKing Tornado 75 edf model only this one has retracts and flaps.

@TwoBrosRC Год назад

Looks like the Tornado was based on a ViperJet. Makes sense given it's a popular scale jet to base model aircraft on.

@fa300ry Год назад

Hi Do you recommend CROW for better landings on this jet ??

@TwoBrosRC Год назад

Not at all. Crow does nothing useful on this jet.

@velcro62 Год назад

So you would reccomend this over the Rafale for a beginner becasue of the lessons it teaches?

@TwoBrosRC Год назад

The Rafale can teach some of those lessons but the Viper is way more upfront about them.
