Engine Heatsink Question

[rag30]

Hey! Doing a 3S upgrade on my Grom and had a question. The old engine had the Arrma thing on top, and it doesn’t fit on the new Hobbywing 2435. Do I necessarily need it or I should be okay! Thanks!

No you don’t but a fan and or heat sink are to help keep the motor from overheating. I’d find a heatsink and motor fan combo to put on it to make it run cooler

The harder & Longer You Bash ,the more likely you'll want the heatsink & fan combo.

Im doing the same exact swap to mine in the near future, just waiting on some suspension mods to come in.
Can anyone recommend a heatsink/fan combo that would work, or a place to maybe search one down?
I saw in another thread where the builder used this pad:

I imagine he cut it down wrapped the smaller new motor and installed.
Think this would work?

IF you can find a way to mount a fan near the motor so it blows air across it.... that should be all you need. The outside case of the motor already has fins and will work fine with a fan blowing on it.
