what size heat sink?
 

What size RCM heat sink fits a 1950\7? Just wondering. Will not use the end piece. No worries.

19xx LMT motors are 36mm in diameter, just like Feigaos, so Mikes heatsink/clamp will fit sans clamp.

A 1950 is 76mm long, which is 2mm shorter than an XL motor, so if you use the HS/clamp, it'llbe a little short...

Thats perfect!!!! I was not going to use the heat sink as its #1 job anyway. instead of mounting it on the top of the motor like it should be I am swinging it under the motor. It will be used as a support more or less. The front end cap keeps pulling out of the threads inside the motor casing on the 1950. So it will be more a support than a heat sink. :lol:
