The performance of this plane on the stock motor was dissapointing to me. I went to 8 AAA batteries and it was much improved.

Now I am running an 8 turn Astro 010 in the GWS gearbox modified by www.parkflyermotors.com

I use a 3 cell 1200 mah e-tec pack. The plane has unlimited vertical, takes off in 5 feet and flys for 20 minutes if I use full throttle about 25% of the flight.

I fly it almost every day.
