Maiden flight!! feel free to spread the video link. Remember 1080p

need suggestions on how to improve this plane or other inputs here in this thread or on youtube.

Giant RC SU-37 Super flanker jet, Maiden flight, MUST SEE! Scratchbuilt Depron electric pusher prop (9 min 44 sec)


Second and third flight with Go-Pro onbard cam

Giant RC SU-37 Super flanker jet, SECOND AND THIRD FLIGHT, Scratchbuilt Depron electric pusher prop (10 min 49 sec)


What do you guys think about my battery and motor choice?

I want some speed, but high alpha, and aerobatics are a higher priority.

Struggling a bit with the setup on my new dx18, i want to toggle elevon on and off on switch, and i dont want the ailerons to move up when the elevators move up.

i want a "normal" setup for high speed rolls and loop, and a aerobatic flight mode for high alpha and aerobatics, with elevons, spoilerons and bigger canard movements.

I like your project, pretty cool. The SU-37 is the most beautiful bird of all Shumate jets. Do you have an estimate on your total flying weight?

thanks ive built this in one and a half week, got so eager, couldnt stop cutting depron. Im guessing around, 4 to 4,5 kg wild guess. Thrust around 6 kg.

All electronics are on its way to my mailbox, cant wait to install it

awsome build
Can't wait for the maiden, you need to get your video buddy to join.

go hersker

as for the motors, if math is wrong, its my fault.. but feel free to correct it. 11x7 3 blade or 12x8 2 etc, all seem good, and within spec of motors at 1300w aprox each.

The cat is very curious about the su37, and slightly annoyed its getting so much attention.

My gf started to get contractions a couple hours ago btw .

I ordered a "lander" retract system on eBay for the su37
147 mm long legs, 70 mm diameter main wheels.

Congrats on the pending baby!

The SU37 is very cool. I'll be curious to see how you tackle the gear as I'll be getting back onto my similar project soon.

That is the retract kit i bough, 147mm legs, full metal lander

I havent decided if i should mount it inside nacelle or under wing And make a slot in the fairing coming from the rudder, what do you think?
