I have a ship that I plan to use in an SSC contest August 28. It is an Avenger 972s originally designed for slimer combat. With no mods, I converted it for electric use.
Here is a link about a few attempts, and pics of a current working model from the RCCA website. http://www.rccombat.com/forum/topic....24&whichpage=1

The 'E'venger is powered with a Himaxx 2825-2300, and 3s lipos that can provide 30+ amps. It turns a MA 8x3 prop at 15500 rpm static, but unloads and flys the ship nicely. AUW is almost 3 lbs ready to fly.
