The heat sink you have is good for cooling. It won't help hold motor together
though. I have messed a motor up like that. Just for reference.

I peened the can to the endbells with an awl and hammer. The heatsink also has two 4mm bolts that go into a slotted mount that extends from the upper frame plate. It keeps the motor from flexing the mount, which keeps the spur from getting thrashed. It also transfers heat from the motor into the frame.

I've heard stories about XLs blowing their guts out during a crash and didnt want to risk loosing a motor, controller, and God knows what else. I ran for a long time with just the motor peened and had no problems other than stripped spur gears. I have a pic on the next post:

You can see the peening were the blue can meets the aluminum.
