Si`s X11 motor did the same thing as MRD`s, the solder melted but hey it is Si
it reached 105 ish then game over! Is there an option with the setup you have Dave to adjust the motor timings ie via the motor or the speedo i`m guessing yes so if i were you i`d drop it down to low/normal and see how it goes... i have been advised from losi on 2s lipo`s with 4.5T no higher than normal on the motor timing , as i`ve had 2 speedo warranties now
