boost was set to 5° (10000 - 60000 rpms) and turbo to 25° (instant on full th). fdR was 7.7 (touring car). with fdr at 8.3 it did not shut off but was slow on the straight. i enabled overheat protection on the esc for 125°. after approx. 4min it just shut off.
never had that problem before. any setups that are maybe faster and still produce less esc and motor temp? need top speed on straight mainly. motor never coming off hotter than 80°c.
thx for the help
If you've got a long straight, I think the level of turbo your using is too high. Mod motors are quite sensitive to small adjustments in the boost and turbo, so even only dropping 2 steps or so can make a big difference.
Looking over the settings, I would go with more boost, and less turbo.
Try the following... which is not dissimilar to what Andy Moore uses (last time I asked anyway!)
FDR 8.0ish
Punch - 12/15, linear
Brake - 20/20 linear, 67.5%, 8% drag
Boost - 24steps, 12,500 - 27,500 rpm, linear
Turbo - 18steps, Delay 0.15s, 12°/s Engage, 18°/s Disengage
If you need more straight line, up the turbo to 20. Also, running a fan on the motor and esc is a must!
Hope it helps.
