This is the method of control. The only mod being a D1 sticker. For an entry level RC it's not bad. It has drive rate adjust, servo reverse and end point adjustment (have to do that one day)
It also came with a speed control. But since I upgraded to better batteries, that has stopped working for some reason. Maybe melted something after running longer. It's my next upgrade but it has me thinking about 2.4ghz /Lipo and Brushless at the same time, so I think I'll be without reverse for a while.
