    What would be a good ABC prop to start with? Putting in a CMB 21 Bretta

    Thanks

    I thought you were running Nova. DD. Maybe a lighter prop like Buck n Brad said.

    Bryon,
    My Beta Evo pulls everything from 1717's through 1819's. I am still going through the learning curve of running 21 motors.
