Im running a SP 4.5 with a mamba max speedo at FDR 7.5.After 5 min on full throttle motor temps are very low (motor 110F,esc 95F).I have to gear up a couple of teeth ( I need a little more top end) but i don't know if i have to adjust the timing also.And if i have to do this do i have to adjust it from the timing ring on the motor or from the speedo?Now its on the normal position.Any suggestion please?

Mr_Orange

If you are going to adjust the timing with sensorless you need to do it from speedo as timing on the motor only moves the hallsensors position.

Hi all,
we've just purchased a SP34813 13.5 motor to run at our local club, and I have a couple of questions. We have run 4.0 and 3.5 motors up to now, which have the replaceable sensor board and adjustable timing backplate, but this motor appears similar in design to the LRP motor that my friend runs. The instructions mention adjusting the timing plate, but I assume this relates to the larger motors?.

Am I right in assuming that the rotor is bonded?, and can a sintered unit be fitted?. We run an LRP sphere competition TC speedo, will this motor run ok with the extra 30 degrees of motor advance that they seem to have?

Finally, what approximate gearing startpoint would you suggest for a 23m x 12m rubber tyres on carpet track, it is medium technical with one full length straight.
Many thanks
Phil
