This happens to me on most of my chassis and I m sure it happens to a lot of you guys as well.
The plastic clip on the motor assembly that holds the heatsink in cracks very easily after changing motors several times. Even if you have the Bit-Racer tool (comes in the GM-xx bodysets) you still can have this happen to you.
I ve found this fix a very handy one that works quite well.
1) Remove the heatsink and motor.
2) Drop a small amount of superglue on the cracked area, spread it around with a small piece of wire.
3) Do this to the top, side and bottom of the plastic clip, spread evenly.
4) Let this set for 30 minutes.
5) Sand back lightly to even out the surface, use 400+ grit sandpaper if you can.
6) Repeat 2 -> 6, 3 times. You can do more, I ve found 3 times is fine.
All done! Use good quality superglue like Selly s Quicktite or something similar. Those crappy superglues that are $2 in those cheapo shops aren t worth the time….
