Just an update guys,
A friend of mine at properly discharged and cycled my stock 7 cell nicad battery 2100 mA.
He explained to me that how fast the motor runs is a property of voltage. 8.4v in this case.
Anyway boy what an improvement. It flew great. I might add that the great planes gd-600 list magnetic mahem motor as an option. It is a good motor and way better than stock.

But I would/will next go to the EndoPlasm it'll spin faster, go with the 12t gear and 12x8 prop as suggested by the other guys on this site, The stock esc works fine up to 7cells. so I'm going to get a 3000-3300- nimh battery next. so try that guys .
