Speedo control cutoff problem

[Chris Elworthy]

Alright lads,

I'm new back to racing and am experiencing some rather strange problems with my speedo or possibly motor. I'm using the Speed Passion GT2.0 speedo with Thunder Power 7.5 motor in my Losi 22.
What is happening is, around 4 minutes into the race the power from the motor will cut and the buggy will grind to a halt, the steering however is not effected. If you then switch the speedo off then on again the car is back to normal as it was before the cut. The speed control has recently been returned from Schumacher as I thought it was faulty earlier (turned out to be a faulty transmitter) so has been tested and is supposedly fine.
Other observations are that the fan had stopped working the first time I noticed the cut in Power and hasn't worked since, this shouldn't be too much of a problem in a 2wd though.
I've been back to the setup box and reduced the voltage cutoff to 2.8 and alsO tried a reciever capacitor but no joy.

Has anybody an idea of what could be happening? Is it possible the motor could be damaged causing the issue? I doubt it matters but the car is being powered by Orion 90c 5500 Lipo's which are brand new.

Has anybody got an idea of what may be the issue? Its a really frustrating problem as you only know you have it when it's too late
