[tcboy1983]

Hi I am getting the new speedpassion v4 17.5t to race in tc blinky I race at aldershot adur Cotswolds and westlondon and just wandered if ppl had used them and what's a good starting fdr and motor timing to start with
If you also let me know the motor temp after a run that be great to

3.5 dropping to 3.2 FDR for long flowing tracks
Not seen a V4 motor but I run my G forces at 35 of 45* tried to run 40* on 4.0 (indoor carpet) but motor was coming off hot (couldn't hold it for 3 seconds 80deg*?) reduced to 30* and reduced FDR to 3.7 temp was just warm so tweaked up to 35*
It will be try it and see but 3.5 would be a good start tweaking the timing up and checking temps
