I love this plane! At first I had many crashes on take off due to torque steer to the left on the ground and roll once in the air. I read the reviews and was using a 3S Lipo but it needed alot of runway to take off. If you use the 3S battery go to an 8x6 prop and bend the landing gear to give more hieght so the larger prop will clear the ground when the gear flexes on landing. Trim out some foam inside the wheel pants to give the wheels more clearance or they will bind on turns or in a crosswind on the ground and nose over. I also added a 3 axis gyro stabilizer for better 3D handling.
