Hey Gauravag;
Flying is great; you just have to work a little bit on diff. aileron and roll-yaw coupling; always with radio mixings. Just put the CoG where the plan say and will be OK for almost any maneuver. Low speed is gentle and lands very very well with high angle of attack.
Woods quality of mine is great; also accesories except for the landing gear (poor alluminium, i replaced with carbon fiber). I replaced also the wheels.
I don't even like the wing attachment nor the canopy attachment; but they're OK, It's just I don't like. I will chance them as soon as I can...
What engine are you planning to use on it? What radio?
Here is a video of a TO with teh Supertigre 90; no videos available yet with the OS 1.20. Servos on mine are: S3003 and hitec HS-695MG for rudder.
