Take a look at Big Tone's Park Zone T-28 with his own creation of Flaps....this model exhibited an incident with a Smoked Brushless Motor and ESC that Park Zone provided......Toney installed his own Brushless and ESC plus an external BEC. The only thing he still uses from Park Zone is the 3-Cell, 1800mAH, 15C discharge, Li-POLYs and the charger that came with the RTF.
The Flaps he created just slows this RC Model and makes it look like the Full Size Aircraft!!!
