I did some playing around with numbers for the stock brushed motor on this heli. It looks to be around 11,000 KV. I know someone was looking for this number earlier, think it was bytemuncher.

Thanks for the fets spec, they arent to bad of a job to replace, a little easier to do than the mcp-x fets IMO, just desolder one 4 leg side at a time with a iron, using a little mini flat screwdriver as a wedge under the chip. With enough heat all 4 legs will pop-up, but dont force it and take the board traces up with the chip......Then do the other side, and then resolder one side back at a time with the new chip.. You can solder the drains together on one side, but source and gate cant short.... Walkera loves to use these Fairchild power FETS since the Walkera 4# FP These are rated at 7.5A
