the esc on my plane seems to be overheating or some thermal detector deal on it kills the motore b/c of the extreme heat at my house. if that makes sense . will it make any difference at all to drill or cut some ventillation holes maybe in the canopy or fuselage? i just wanted to check with someone before i do something wrong.

thanks

In a lot of situations, if you drill an air entry hole directly ahead of what you want to cool and then place an exit air hole that is about 1.5 times the entry area, you'll be all right.

You want the entry hole in a surface that faces the airflow, and placed to have air forced into it. And you want the exit hole(s) to be on the aft surface of something. Anyplace that's tapering back down or tapering inward has a better chance of pulling the warm air out.

The very front center of a bubble canopy will often be the right kind of surface for an entry opening. And almost anyplace like the aft part of a bubble canopy will be a negative pressure area and pull the exhaust air.

It's perfectly OK to add small scoops to route cool air directly on ESCs and batteries, especially the batteries. A specially located scoop can often be lots smaller simply because it directs the air directly at the thing you want to cool.

It's pretty amazing how little some know about cooling the battery and escs. There is a line of electrics that's recently had it's price slashed to about $25 each, that actually encloses the battery completely in a closed box that's only slightly larger than the battery. Amazing. I wonder if the price cut was to dump something that was basically braindead designed.

ok i understand ill try and brainstorm it a little bit fisrt and see what design i can come up with. thanks a lot and ill reply back and let you know how it went!
