RCPowers Mig 29 v2 re-maiden and review.



Sorry about the grainy quality! Cheap camera + low light conditions = poor picture quality. It's watchable in 480 or 720p tho.

RCPowers Mig 29 v2

  • RCTimer 2826-6 2200kv outrunner.
  • RCTimer 30A Programmable ESC (might need a 40A, might need plastic spoon scoops for the ventilation holes, I'll figure it out tomorrow!)
  • 1600mAh 3s 20C battery (might be better off with an 1800mAh 20C or 1600mAh 25C).
  • 2 servos - Elevon only.
  • Stock KF2 aerofoil
  • CoG is set 1 inch behind stock.
  • Throws are stock 1.5 inch
  • No Expo (stock = 30% on elevator).
A very nice plane. This setup isn't the fastest but is wonderfully aerobatic and precise at low or high speed on just elevons. High alpha actually takes less throttle than cruising speed which is nice.

I'm flying on no expos. The plane is just so smooth that having a bit of skill with fine control on the sticks was all it needed. For a plane so aerobatic it's very stable and IMO you just don't need expos on elevon only. If you are a beginner it's probably a good idea to start with the stock 30% expo on the elevator tho.

Enlarging the elevons was a good call. There's plenty of pitch and roll authority to have fun with as long as you don't expect to roll like a drill (mind you I mostly stuck to 3/4 stick being a "re-maiden", having made alterations). If you put on a 4x4 or linked elevons you should be able to cut the elevons down some for you guys who keep breaking them.

I'm being cheeky and I've flown it pre-bevelling of any leading edges just to show you don't need to go to the effort if you don't want to (or aren't sure what you are doing)! The speed suffers a little but the aerobatic capabilities obviously aren't being effected.

I've gone light because I don't have a huge field to fly in. Although by the time everything is bevelled/rounded I'll gain speed, I don't see the Mig 29 V2 having any problems carrying something like a Megajet V2 (or any generic 2836 motor). While I doubt a 3s and a 6x4 prop will provide any benefit over my setup, a 3s and a 6x5.5 prop or a 4s and a 6x4 will be a definitive speed boost. The stall speed will go up over mine but it's exceptionally low as it is, adding a few mph to it isn't likely to create any drastic issues.

F1 was spot on with the "1 inch back" on the CoG. The plane is about perfectly balanced. There's no nose or tail drop on a roll. It took the nose drop out of it on sharp turns and also took it out on a stall (I stalled it at the end of the high alpha run). I climbed at about 45 degrees on it's wingtip and the nose didn't drop there either. I prefer a touch nose heavy but I'm just under 1 inch back and it's perfect.

I also had zero trouble with orientation even with the light as low as it was and the plane being unpainted. The plane has a distinctive profile from most angles making it very easy to keep track of.

Even slowing down and dumping the throttle to make sure the prop was working hard there was little torque roll to deal with.

And when I say "effortless" in the video I mean it. This plane went from maneuver to maneuver smoothly without any complaint what so ever. Pitching and rolling violently just led to a quick but smooth change in direction. When it stalled at the end of the high alpha run it just sat there, you can't even tell in the video that it happened. Climbing at 45 degrees under nearly full throttle with a slow roll to invert for a split S, a 1/4 loop at about half stick and then a savage kick of full elevator for the rest of the loop out and.... well if you look at about the 3:15 mark of the vid you can see for yourself. It was happy to do it.

All in all this is a plane I'm really looking forward to becoming friends with.   

Regards,

Grey.
