    How many times does it hit the rev. limit at the start? Usually, 3 MM in the heat. Probably end up with 5 on the tail.

    I haven't run it yet, I have been building this over the winter for the race season, was just looking for a starting point for the prop when testing.

    Don't go over 2mm at first, because all machines act different. So start a 2mm.
