How hot can my receiver get in my Aspire

After about my third motor run, I land and ck the cp1300 8 cell pack. It is very warm, almost to hot to hold on to for very long. If you are fimiliar with the Aspire you will know that my radio receiver sits directly underneath the battery pack, (two wood rails). After a long flight (3 motor runs) I remove the cp1300 battery pack and I feel the receiver and it is pretty warm! I haven't had any radio problems yet. But could it be a problem. If it is, do any of you use or could you suggest some kind of light weight insulating material that does not reflect radio waves etc.

Most pieces of electronics equipment can stand fairly high ambient temperatures. Even quite sophisticated computerised kit can work comfortably at temperatures above 50 degrees Centigrade for short periods of time.

The receiver case should provide reasonable heat protection to the circuitry inside. If you are concerned, you could add a layer of light ply or balsa between the cell pack and the receiver or even use a strip of thin aluminium (which could double as a heat sink for the cell pack). I personally like to keep my receiver well away from the battery pack as I regard it as both a source of electrical interference and an RF screen.

Hitec receivers come with a foam wrap that would work fine..

hi temp

we design and test our receivers for 140 degrees F (about 60 degrees C) but i would not recommend running them at that temperature for extended periods of time
