    Stock motor safe max rpm

    I would like to know what is the safe max rpm with stock internals. I know Greenhulk has run 8900 but I would like to know what you are running and for how long.

    I know of people running 8750 in stock engine for a while, don't know how long it will last. I have been told to keep under 8500 and I will be fine.

    In the Vipec maps from Riva the maps for the stock map is target prop speed 8600 and rev limit at 8800.

    Hi there,

    Yes, I'm running a VIPEC. NO, I just tested and the motor is idling at 1500 RPMS give or take 100 RPMS out of the water.
