However, until now I've had a string of hard knocks and outright failures of the motors, batteries and speed controls on this plane. Or should I say I knew nothing about brushed or brushless motors and so I kept blowing them up, putting on the wrong props, and generally releasing the magic smoke from the speed controls.

So fast forward to this year and I now own a watt meter, a big selection of Li Po batteries, and the beginnings of a creeping knowledge of how to put all this junk together and not smoke them. Gosh I'm hard headed but I like to think I eventually "get it." Originally this plane came with a geared speed 400 brushed motor spinning about a 10" prop. It was powered by a 7 or 8 cell NiMh or Nicad battery pack. Back when it was new I'd fly with the 8 cell AA pack out of an electric Zagi and it would fly but gosh was it heavy. That gearbox started to go bad and I never did have luck finding a replacement that wouldn't grind hard too.
