Just wanted to pass on some info. If you have a 40 size Hangar 9 Alpha Trainer and are getting bored with it's performance here is something you can do for less than $10.00 to signficantly increase it's performance. Purchase a 10 x 7 Master Airscrew Prop (MAS1070G3) and a Prop Driver (EVO100219). Remove the three blade prop and the weighted flywheel and install these two items. The result is an airplane that is much more acrobatic and flies about 20mph faster. Saves gas as well because you generate more thrust at lower throttle settings due to the prop being more efficent as well as the motor with the weighted flywheel being removed. See attached pic. Any questions/comments shoot them my way.

Thanks.

Tom
