Delta Force 28 Pathfinder

Just an observation with the amps your pulling and low speeds I feel your probably running way too wet. Large controller and weight too forward, None of the props you mention give enough bow lift. My DF 28 runs 52 mph (83kph?) with a 3660 leopard 2050kv 4S and 1714ABC, 49 with a CNC 442/3. My 443/2 runs 45mph. Get more lift in a prop or move your motor and esc to the rear.

Thanks Mic that's some good points you make. I've got some new props coming to try, and I'll put the ESC back in the rear of the hull, where I initially was planning for. The motor position is too much effort to change. Oh and I measured the COG, it's currently at 39%.

Ugh, well moving a motor is some work, but imho definitely worth it. I’ve never had a boat that wanted more than 33% cog.

I think moving the ESC to the rear will be not too difficult. It also should let you know immediately if weight is an issue. Good work, keep testing and share your results to benefit everyone.
