I just bought 2 of these for my Feigao motors and they are outstanding. I got the "S" size for my Feigao 7L and it fits perfectly. You just have to use longer screws on the back plate to hold it on. I'm really glad Mike makes these great products.

I have used a few of Mike's brushless heatsink/clamps over the years and they have always been exactly what I've needed for my Fiegao motors.
Hope these come back

Great for saving the end bells on the Medusa series motors and for extra heat disipation...
I add a little AS5 (Arctic Silve 5)to help thermal transfer...
S for 50mm L for 60mm XL for 70mm (with RCM from end bell plate) XL for 80mm
best heatsink, by far!!

had one of these for an old Lehner i had on my emaxx.... fit was perfect, and the motor was definitely cooler as a result. THANKS MIKE!!!
Best heatsink around!

I had 3 of them for my B50 Hackers and Feigao motors. It works great with thermal compound and keeps my endbells in place. Still run one on a 5s B50 motor and temps stay in check in the Texas Summer. Also kept Medusa motor endbell in place.
