RE: Doubledog's building a luftboot
It will have good slides on the truns no doubt. As stated above a little smaller on the boat would give better prefromance, and at the same time what you have now will run just fine. Just one thing I would change, the 14 x 7 3-blade is going to load your engine some and not let it get up to the power band for the G23, you will have better results with the APC 14 x 6 2-blade.
By the way welcome back, LOL its been some time since we seen you.
