You said in the 1st fight it cut out, I was just guessing it might be the thermal trip cutting in.

Might be worth seeing you can get the speedo upgraded to the HE version as its 140amp, think it got double the number of FETS to (someone who knows roboteqs better will know). We looked at both the HE and Mega Wotty to run Mutes Lems on, we went for the Mega Wotty because it fitted better.

We stick the speedo directly to Mutes chasis and us the whole robot as a heat sink and we've never had it cut out
