Summer and extra cooling

[Stoomstrijkijze]

Hi guys,

I've bought an eight last month. I'm really happy with it and it drives good! I got an extra Jconcepts that needed a paint job. I've painted that body 2 days ago, but the heat is a problem now. Temps are getting up to 74°C when I'm driving on grass. It's a bit lower when i'm driving on sand.

I drilled some holes in the front window and in the back of the body, but it doesn't seem to help that much. Maybe because I'm not making enough speed in my garden and constantly accelerating.
If I take of the body for 1-2mins the temp drops immediately to 45-55°C.

My gearing is 15/45 with a 2200KV MMM engine. I think that ok? It's geared for 67km/h (42mph).

With a nitro body, the temps are much lower 55-60°C.

The ESC is okay because of the fan. ESC temp stays always under 55-60°C.
