Doug,

The goal of this conversion was to make an EP Q-500 go as fast as a TT40 pro powered Q-500 on the long course as we fly it here in the Midwest as a plug and play system for the same cost and same weight. That goal is close to being accomplished. The longer motor, higher Kv, and 9 x 7.5 APC "E" will seal the deal and accomplish the goal. Now, I think the monster needs to be controlled with a set of guidelines. If there is interest in this type of event, then we need to see where the interest lies. Do we keep it with the power system as flown to keep the speeds down as a beginner class, or use the Wingman with the same larger power-system and control it with props?

My suggestion would be the following:

Wingman II event be limitied to the 35-48-1100 Turnigy SK Aerodrive XP Out-runner motor, 10 x 5 APC "E" prop, and 4S1P 20C 2500 MaH Lipoly cells. Fly this event on either AMA 540-B (2) pylon course or AMA short course. (Min weight 3.5lbs)

EP Q-500 to use exsisting legal Q-500 airframes with wood wings like 424. Use a 1000 watt-min limiter, exposed motor, 9" min prop dia, and fly on AMA long course. Same commercially available non modified prop rule as 424 and 428. Weight to be the same as 424 & 428 (3.75lbs) Might also specify only out-runners as to keep the cost down.

Now, if clubs are interested in flying the EP Q-500 and can't support the course requirements to AMA safety standards, then a provision for AMA540-B (2) pylon course be used and limit to hand out props which I would suggest the 9 x 6 APC "E". A motor requirement might also be needed to keep speeds down in the 100 mph or less range for that.

Any thoughts? Could we have something here?
