HPI Flux Temps

[ASR]

Hi guys, just wondering what temps your motors are running at, i clocked up 186 deg with my 5.5 today in coolish breezy conditions in a 4wd durango on a semi grass/astro track!!!!

I'm running a nosram pearl istc on lowest power profile and lowest timing on the motor with the internal fan, on the same gearing as other guys at the track.

All basic checks have been done, transmission running free, connectors etc (been in this game for a while and on for my f2 this year) but i've just about run out of ideas.

At the start of the run when the motor is cold there is instant punch without hesitation, however at the end of the run when hot, accelerating form a standing start it stutters and doesn't pull "cleanly".

Motor is almost new.

Any thoughts because i'm out of ideas.?????

Thanks
