Hi Bassman,

Yes, sharpening and balancing the prop means taking material from the back of the blade (the side that faces to the bow)

If you're happy with the boat speed you should work on the ride attitude by moving the CoG forward, to get a more level ride.

I run electrics and have my batteries to shift around, in your case it means ballast in the nose I guess, trimtabs on that hull would not be very scale-like, but effective, keep them as small as possible (and painted grey).

I've been experimenting with a similar hull 29,5" long, testing different motor set-ups. The shape of the hull made it run best with a light 7-cell geared down 600 motor, heavier motorisation with 12 cells and a direct drive 700 motor on a 40mm prop, made it blistering fast, but also unsteerable as the entire hull would be on the plane and the rudder would stand in an airbubble, very scary when running towards a brick wall...

In my gallery there are two pics of the scaled up version, 43" long, not quite finished due to lack of time. The Plettenberg motor in the first pic will be able to propell it to very un-scale-like speeds.

Regards, Jan.
