There are guys running the Thunderpower 17.5 that are a second a lap quicker than I am (20's against 21's) I run with a consistency around 0.2 - 0.3 but this motor so far is a huge let down. (That said the D3.5 was worse)
Just a note regarding the timing. This motor zero timing is actually zero, and many motors zero can be any where from 28 to 34 degrees. You mention LRP and the 2 dot which is approximately 32 degrees.
For 17.5 Blinky start at 36 degrees timing and gearing will depend on the weight limit your using, along with the track size.
To answer the heat question there are several items to discuss. The first is that this motor will typically run 15 or more degrees cooler than most others. So if your gearing for motor temp (which i do not recommend) more than likely your past the optimum performance gearing/timing. As stators (any brand) get hot the resistance of the copper wire increases, and performance drops. Racing in southern california is not unusual that our ambient temps are over 100F in the summer months and after a run motors will come off the tracks from 160 - 185 and experience and results show we have done extremely well.
If you have support questions I actively support through email, both inquiries from the website and direct through support @ schuurspeed . com I welcome calls but am often at a track and its difficult to hear at times so email is preferred.
I appreciate all your support and look forward to assisting as possible.
