I put no down thrust nor right thrust on my Avia and it flys fine. Any fight path tendancies under power are easily corrected with the controls. Also I made no provsions for cooling as it really isn't needed. With the climb rate the motor only runs about 20 seconds before I'm at 200 metres altitude.
