Hi everyone,

Greetings and respects to all.

Health reasons sadly prevent me from racing but I am eagerly hoping to build one of the next batches of Durangos, and just ‘race’ it around the lawns and paths of my home.

My interest in rc cars was recently re-awakened by Tamiya’s Buggy Champ re-release, having built one of the originals in 1979.

To the re-re I fitted an Orion 19Turn motor together with a Novak GTX and a Spektrum DC3S radio system. But found at the modest speeds I use (typically 8MPH or so for periods of 20-30 minutes, with the odd burst up to 20MPH) the GTX would get very hot and needed fitting a large heat sink on top of the existing one.

So my concern with the Durango is that if I fit it with best quality electronics which it deserves, say the Tekin RS Pro and Redline motor or something similar, even with the TX’s throttle travel set to 50% will the esc overheat if not running flat out all the time?

I have thought about using the Durango’s chassis as a heat sink and if I could thermally couple a metal clad esc such as the GM Genius to it. But there doesn’t seem an obvious answer as everything is of course biased towards all out racing

Perhaps it is just getting the esc set up correctly and the motor gearing right, but I just don’t know - but perhaps someone might be able to help.

Many thanks for any comments or suggestions in advance.

Cheers

Gino
