Center of Gravity : The battery was heavey and also located in upperside on the frame, so the airplane couldn't stay blanced. so I move the receiver on the motor bracket, change the batter to the lighter, then move it right next to the bracket. {{:img_5817.jpg?200|}} 2. Motor Bracket : I grind the bracket because the small hill in the middle interfere the connection between the motor and the screws. {{:aileron.jpg?200|}} 3.
