Thanks for the kind advise. I am running (i.e. just running round a make shift track, not organised racing) a pair of sacker buggys one with a hobodies 0.26 hijacked from my pro truggy while the other has a brushless system in it. I agree with you that I'm probably going to ruin the 0.26. Already killed the original glow plug because somehow managed to wedge the glow starter on the plug & can't take it off.
Trying to outrun the local boys who have much more experience in Nitro than me. Of course, I can always smoke them with the brushless but only until the battery is flat in less than 10 minutes.
Sign...long learning curve ahead.
