Piloting PRECISION RC Plane Aerobatics (E-flite Viper 90mm)

[@Viperdriver-F16]

Wow excellent flying Tony! Jon you did great on the camera too and I really enjoyed the commentary. What a team! Keep up the great work!!

[@TwoBrosRC]

Thanks so much, Jay!

[@jh1982a]

He's truly great on the sticks... I like his style

[@Danny59330]

Love that Viper 90 Definitely want one !

[@shanehoule9477]

Sweet plane

[@davidgerlach1132]

Fantastic flying, Tony, and great camera work Mr. The day has come... Incoming is second Viper (I currently own the EF Viper 70mm), this beautiful Viper 90mm aircraft is second to none. I love the Viper, for every reason. I'm also curious for maximum rudder authority in a precision knife-edge with this Viper 90mm, do you move the position of the rudder hole on the rudder horn to the innermost position for maximum physical throw, or travel?

[@TwoBrosRC]

We used the outermost hole on the arm and the innermost hole on the horn.

[@zachgray118]

Damn tonys got some skills! Maybe we can see some more role reversal in the future? Steady with the camera aswell jon!

[@TwoBrosRC]

That's the idea - I'd like to get him performing maneuvers more often. Thanks man!

[@JT83_RC]

Hey Jon been watching ur channel for a bit now never commented yet so this is my first😄 u are awesome pilot with lots of energy, and ain't afraid of telling the community what ur true thoughts are on all the different models u fly keep it my friend.💯💯👍

[@TwoBrosRC]

Hey man, thanks for the feedback!

[@FENIXRC]

Like friend saludos ✈🤩

[@gigadodo00]

How would you compare flying the freewing f18 90mm vs this viper? I have the f18 and really like it, but this viper is super tempting.

[@TwoBrosRC]

The Viper is more stable in the air but it's less agile than the F/A-18. I like both but prefer the Viper.

Very cool flights, congrats Anthony for your skills :) and well done bruh for that filming, wasn't that easy...

Absolutely. My shoulders and neck hurt pretty bad after that. Thanks Arthur!

[@crotaflyingsolo4759]

Hi Jon, just a thought, why not bring a weed Wacker out to the field someday and smooth out that lumpy growth in the cracks to give yourself and your planes more enjoyable takeoffs and landings?

[@TwoBrosRC]

Thanks for the idea! Unfortunately, here's why I won't be doing it: I don't have a weedwhacker powerful enough to clear the taxiway. I brought my electric out a couple of months back and gave up - it simply couldn't get the stubborn crab grass to remove itself from the pavement. I use about 388 feet of the taxiway to take off and land. This is a lot of space to clean up by hand as we're rapidly approaching summer and the hottest part of the year - the part where NWS recommends that you stay indoors until 8pm or later due to extreme humidity and heat. That being said, I did empty most of a container of glyphosate on the taxiways after doing some F-22/Ultimate 3D practice off-camera a couple of days ago. If all goes well, it will have been defoliated by the next time Tony and I go out to shoot some footage together.

[@crotaflyingsolo4759]

@@TwoBrosRC Ah Ha, I see. By chance do the Airport Maintenance people that sometimes cut the grass you had mentioned once I heard you say, might be enticed with a bottle 🍾of their favorite beverage to do it if they have the equipment? 🤔😉👍🍾🍾 Just a thought.

[@TwoBrosRC]

Very doubtful. The guy who cuts the grass only does it because that's the payment for being able to set up shop on the land with whatever business he's doing. He keeps the grass on the property mowed and the owner lets him do whatever on the land so long as it doesn't encroach on airport ops. It's a weird arrangement.

[@crotaflyingsolo4759]

@@TwoBrosRC Well, ok, but next time you see him passing by, a friendly Hello and the inquiry couldn't hurt? ;-)

[@sirstomper]

Hey Jon quick question on those AGFrc B13DLM servos for the Viper, do they drop right in place or is there modification needed and where did you make the splices, all the way at the connection at the root of the wing or Midway? Thanks

[@TwoBrosRC]

They're a bit bigger than the stock servos so you'll have to cut the little wings off them and sand them smooth, potentially, before they'll fit into the servo pockets. Once that's done, they drop in. You can solder the servo wires into the wing pretty easily by just cutting the original servo lead wherever you think it will fit best (check the length of the new servo first) and soldering/heat shrinking the two leads together.

[@sirstomper]

@@TwoBrosRC I've removed The Bad flap Servo and had to remove some of the plastic around the retracts so I can get to the wire but there is not a lot of room there to make a splice hopefully when I get to the ailerons servos it'll be a little easier/more room will see. The new servos are on their way, thanks for your help!

[@mattbaccari8351]

To sustain KE like that, where is your Zeee 6000mah pack placed? Did you have to carve out foam to get it further back?

[@TwoBrosRC]

No adjustments needed. You just need lots of throw and speed.

[@txkflier]

Tony’s almost as good as me.. ;-)

[@sean7193]

Jon , your bad for my wallet. I can only buy one - this or 80mm f-16? I'm thinking this one is looking really sweet, but what would you get?

[@TwoBrosRC]

If you want a more performant airframe, pick up the F-16 80mm. It will do maneuvers that the Viper can't. High alpha is actually much easier with the F-16, and maneuvers like flat spins and cobras are possible with the F-16 while they're hard if not impossible with the Viper. If you'd like to support us, you can pick up the Viper via bit.ly/3JGRS30 and the F-16 via bit.ly/3PZUcEs

[@lancelink88]

Why don't you explain how to do knife edge step by step..that might actually help some enthusiasts....?

[@KB_RC]

Well done Tony!! You are a great cameraman and pilot! Jon you did excellent on the camera as well!!! So your using a GoPro to film this? Awesome video can’t wait for more!👊

[@TwoBrosRC]

Thanks man! This is definitely not GoPro footage. This was shot with Tony's iPhone 13 Pro which is what most of the channel content has been shot with lately.

[@KB_RC]

@@TwoBrosRC Ok so question, my parents both got 13’s somewhat recently but whenever you zoom in, It’s pretty grainy and bad footage…. Did you go in settings to change something?

[@TwoBrosRC]

Pro or standard 13? All I know is that we shoot in 4k and I downscale it in post to 1080p.

[@KB_RC]

@@TwoBrosRC Oh hmm ok… pretty sure it’s the 13 pro… I have an 8 and it seems to have better quality when I zoom in!!! Crazy. Family is going to buy a really nice camera I think and I will be able to use that. Of course I’ll have to pitch in some though lol. It’ll be well worth it I’m sure. Thanks Jon!

[@FFE-js2zp]

Tony is an excellent pilot. One thing I would nit pick is not countering the pro-verse yaw when rolling and inverted. This twists his yaw axis into a corkscrew in the direction of roll while upside down and rolling (1:43). It also happens on his loaded Cuban 8 inverted rollouts, that is on the 45 degree down lines, too, bending left-to-right passes tighter to the camera, and vice versa. E-Flite in their infinite wisdom made it way worse with the amount of differential aileron they include (0:44). Inexperienced aircraft designers think that differential ailerons counters adverse yaw. It does, but only during the upright portions of roll. During the inverted portions of a roll, differential ailerons exacerbate adverse yaw. So you do not want differential aileron in an aerobatic airplane. A better solution is to mix it in as flaps come down, since that is a good indicator you are upright and a high lift flight regime. But even without the beginner E-Flight setup magnifying adverse yaw 2x while inverted, good aerobatics still needs counter-aileron coordinating rudder when inverted and pro-aileron coordinating rudder while inverted. Adverse yaw pulls-on the up-going (higher lift or counter-gravity vector) wing, tugging it backward. Since rudder control is connected in the opposite yaw direction when upside down, as viewed from above, rolls need counter-aileron rudder to coordinate the yaw axis to the flight path while inverted. I think that will help align his Gods-eye view heading changes during inverted rollouts on the Cuban 8 down lines to the flow axis of the maneuver. I would also mix-out the differential aileron in E-Flites beginner set-up to create an aerobatic setup.

[@TwoBrosRC]

Thanks for the feedback man. I let him know. With regard to setups, this is a totally custom setup using brand new servos throughout the flight controls. Nothing is stock about this. There shouldn't be any differential in the aileron movement. I think it just looked like that because you didn't see the ailerons moving in opposition clearly at 0:43 - I didn't really pan the shot early enough to catch it.

[@HAWAII-uh7sc]

Thank you, cameraman, Aloha from the big island of Hawaii. You are outstanding.

@@TwoBrosRC I almost fell out of my seat when you said, "I'm just going to jerk myself off a little bit on that one". I'm 100% using that turn of phrase next time I find myself in a situation where a pat on the back is earned - might be a while...

Hey Tony.... Tony here not bad video Jon 👍 Enjoyed his flying .... Jon makes me nervous 🤣🤣👍👍 Cool bro in law nice he records you for us for that 👍👍

[@TwoBrosRC]

He's a good guy. Can't imagine running this channel without him.

[@richhollenbeck5619]

Jon you need to give yourself more credit, I think you did a great job with the camera work. You need a burner for your viper. Tony did a great job with his precision maneuvers. You mentioned Tony is a hornet pilot and he flies DCS, do you listen to the fighter pilot podcast? If not you should check it out.

[@TwoBrosRC]

Thanks Rich! I'll pass on the burner, I don't think it'll hold up in appearance on this jet. Just isn't my thing for civilian jets. I tried it on the 70mm and only liked it because I changed out the nozzle for the F/A-18C nozzles from Freewing. Tony is more than just a simulator Hornet pilot, he's Blue Angel #5 on the Virtual Blue Angel demo team: www.virtualblueangels.com

[@NeedSpeedRC]

Smooth flying! I really liked how tight and deliberate he made his routine look. You guys are definitely raising and setting a new bar.

[@chiefbd]

Great video, Jon, what camera do you all use to record the flights? I am looking for something like you use to zoom in instead of just using a hat cam go pro?

[@TwoBrosRC]

Tony's phone is an iPhone 13 Pro. I'm not much for iDevices but I can't argue with how good the film quality is. We'll be moving to a proper camera setup in the near future.

[@chiefbd]

Thank you Steffen! It's much harder to be a cameraman than you'd think.

[@propsandwheelsrc1209]

Excellent flying and camera work from the both of you guys respectively there. I’ve got to ask though, what’s the tip stalling tendency on this jet like?

[@TwoBrosRC]

It has a brutal asymmetric stall if you pull hard or fly too slowly in a banked turn.

[@lamaranderson3048]

Atta boi Tone! Dope flight. Juss lookin smooth as hell bruh.

[@TwoBrosRC]

[@double_0_6ix26]

super skills on the sticks. great camera too. seems you both make a great team that can cover each other at opposite ends. would be a super vid to see you both flying at the same time (just putting it out there) understandable that it would be a gopro vid but a small price to pay for us subs ;-)

[@TwoBrosRC]

Probably won't happen anytime soon since I only have one transmitter at the moment.

[@speedyswede5585]

Alright, just add some wind shear, crossing 90 degrees to runway, and oh, yeah a few "rotors" .........actually GREAT flying and GREAT narration with always in the frame camera work! Loved it all.

Great job ! I’m not surprised , I can see the difference in your styles of flying

[@FFE-js2zp]

I love the landing lights. Especially the flashing one, since a flashing LL is the universal sign for no radios.

[@TwoBrosRC]

Or in the case of radio control, the universal sign of a LED that's probably starting to malfunction. ;)

[@FFE-js2zp]

@@TwoBrosRC Yeah, or more accurately, it signals “my owner doesn’t do resistors well.” I know I dont, and most RC OEMs dont. Inevitably LEDs start to flash then die. I kinda look foward to the flashing before dying phase, too. From some internet site: “LED (light emitting diode) lights are low-current electronic components. As such, they cannot be connected directly to a typical household battery without running the risk of burning out from too much current. To prevent a single LED (or chain of LEDs) from burning out, a resistor load is placed in the circuit to limit the amount of current that flows through the LED(s). Typical LEDs operate within a range of a few milliamps of current and under 3 volts of direct current power from a battery. A resistor load of approximately 100 ohms will prevent a common 5 mm red LED from burning out. Vary the values of resistor used. Larger resistors will cause the LED to glow dimmer. Smaller resistors will cause the LED to glow brighter. However, too small of a resistor (or too large of a battery) will cause the LED to get hot and burn out.”

[@TwoBrosRC]

Haha, yeah, I didn't bother powering it with a properly resisted system. I just attached a Freewing LED Controller V3 knowing it would kick out more voltage to make the lights brighter and show up better as a landing light. Not surprised it's being overdriven, but I don't mind.

[@roymoon1]

Crow??? Doesn't that destroy some of the lift at the time you want the most lift for the slowest landing speed? Why not flaperons in addition to the flaps? Both hanging in the wind add drag, but flaperons add lift.

[@TwoBrosRC]

Because adding more lift would make it much more likely to asymmetric stall the model on approach. Crow introduces washout to the wingtips and generates a lot of drag, allowing a powered approach that's easy to maintain while sustaining a high angle of attack for a nose up touchdown.

[@roymoon1]

@@TwoBrosRC Could you show a GPS approach and landing speed using flaps and crow vs flaps and flaperons? You are the only one with the skills and set up to try this.
