Did anyone use a heatsink on their Falcon? If so, where was it located (over the magnets or over the comm area)? If so, did you drill ventilation holes?

I have only used one once, and had the motor overheat.

Yes, Chris, some ran heat sinks. I know I did and I think Tony P and Jay Kisling did.

We drill multiple holes in it and usually mount them pretty much in the center of the motor.

Hi Chris,

Yeah, they only help if you drill or machine them so you keep your air flow to the motor.

I had one hole drilled in my heatsink. I guess it wasn't enough. The motor got very hot, and slowed down dramatically.

I will try more/bigger holes. Thanks.

I think JK makes a heat sink that clips over the motor. It is finned aluminum.

I will see if I can get a part # for you. :D

In the West, practically no one runs heat sinks on the TSRs that are similar to the Falcon 7 and I am not aware of overheating. We run max 13 volts, no more. Maybe that's the ticket?

But if we were to run heat sinks I would believe that the vent holes must be kept free, or the heat sink might become the oven...

No heat sink for me and my F7s ran cool on the flat track. They heated up pretty good (as usual) on the King track. I guess the different nature of the "trigger time" between the two tracks accounts for the temp diffs(?).

I move the heat sink as far towards the end bell end of the motor without drilling any holes and it cools the motor just fine. I got that trick from Ralph!
