XRAY - Model racing cars

Hi I am a member of Mendip(Weston Supermare) which is a large out door asphalt track with a main straight of about 70 meters long and I need some help on what settings I should be using with my GM 90 2010 PRO speed controller.
I am running a GM 10.5 motor and am running with standard internal gearing(1.9) and the problems I am getting is that the motor is fine for about two minutes of a five minute run (good acceleration and good top speed) them the motor seems to loose a bit of power. The motor dose seem a little warm when it comes off track after five minutes. I have tried different 64dp gear ratios and cannot get the motor to run consistently for full five minutes could anyone give any advice on what settings for speed controller and what gearing would be a good starting point to try and solve my problem.

Try looking on RCtech forum , there is a GM topic and Martin Hoffer is on there regularly and he will help ya

Have had a look on RCtech forum and could not find GM section is there any chance that you could post the link for the section.

Kevin, replied to you on another forum, but send me a mail with your settings and I'll help if I can

Here is my settings at moment i have adjusted the Minimun timing from 8 to 22 as i was adviced to try.
