On a hand launch you do NOT want to give full up elevator, you also do NOT want to throw it upwards. If it had a better than 1:1 thrust to weight ratio it would be different, but these small park flyer type planes need to be tossed straight out, then allowed to pick up speed before you give any up, otherwise you risk stalling the wing and diving into the ground.

It would be best if you had someone you trust launch it the first few times so that you can concentrate on the controls.

Once it's in the air you want to keep your control inputs small and smooth. Throwing the sticks around will result in a badly dented airplane.

Best of luck, and have fun!
