RC-Monster Brushless Heatsink/clamp

[pb4ugo]

Somebody else is using one with his Lehner by leaving off the back cross piece and using two washers and socket head screws instead to retain and put tension on the rear.

The Lehners won't pop apart easily like a Feigao, but the front has been known to pop off a time or two on some even though they are threaded on.
