Plettenberg Xtra 25-13 motor

I flew this motor last year (2005) with APC 19x12W Eprop. TruTurn is now making a spinner for this motor. Will show pics when it comes.

Thunderpower is now making there new generation batteries of which I have one pair. I have yet to test them, but one thing for sure, they are 2 oz lighter than last years batteries.

I'm flying the "Xtra 25-13" electric motor in my Newly constructed Impact Arf from Composite Aircraft. Here are some specs on the motor and how it performs with various Props.
