WELL I SET UP THE RETRACTS AND WHEN I PUT GEAR DOWN ALL THE AIR LEAKS FROM THE AIR CONTROL VALVE. I SENT FOR A ROBART VALVE THAT I CAN CONTROL THE RETRACT SPEED. I MOUNTED THE AIR TANK AND VALVE/SERVO ON THE WING AND AM TRYING TO DECIDE WHERE TO MOUNT THE FILL VALVE. ANY SUGGESTIONS. WHEN I GET THINGS FINALIZED I WILL POST PIX. "FLY IT LIKE YOU STOLE IT"
