Currently, flapping pushes the flight object off the ground, in a vector that goes directly up. Takeoffs are "jaggy", meaning lots of force is applied over a very short period of time, making things appear unrealistic.
Change the force vector for flapping so it applies more forward speed when speed is low. It may also feel more realistic if the flapping vector was transferred fully to forward speed when the object is traveling as fast as it can.
