Default thunder tiger 40

I'm setting up a 424 racer and am wondering if my rpm's are in the ballpark.

tt40
9x6apc
10% Cool Power

16,200

I got this rpm on the first day of flight for this engine.

Your a little low but not much considering your engine is still new. I don't know if your club is using 10% fuel but the standard is powermaster 15%
