<div id="post_message_16983066">With all the talk about the stock motors failing, I wanted to switch to either a *real* Power 15 or a Power 25 (with appropriate ESC upgrade).

I've heard some say these motors are a 100% direct bolt-on, while a couple said that a different prop adapter and prop (e.g. APC) are needed when swapping out to one of these motors.

Are the Power 15/25 a direct bolt-on, or are the above items needed?

thanks</div><! / message >
