The pics above this message is exactly what I did to the flying saucer, except I have the smart tabs. I also had the power trim on the motor, so I could change the motor angle depending on how much weight I had in the boat.

I explained it on my build thread too, but just thought I'd post it here incase anyone comes across it whilst searching down the track.

I've had a win!
I've managed to resolve the porpoising issue. I flipped the boat and refaired the aft 3ft of the bottom. Most of it was good, but the last 6inches needed some filling. I added up to a 1/4" in places. The boat now rides beautifully. I still have the smart tabs, but keep them up unless I have passengers in the back to help get up on the plane quicker.

Top speed is sitting around 33mph.
