Three point hydroplane help,

6,499 XVIindustries  8.9 years ago

Just made a nice looking very streamlined fast powerful hydroplane
It's a three pointer, can currently get up to 285mph but that is at 30% throttle lol but when you increase throttle above 15% and the boat accelerates above 300mph it starts bouncing from side to side and then flips up out of the water and spins around... I know instability is a common problem with three point designs but how is stability increased?

    I found that a strong dihedral for the wings that are in the water helped on mine. Also spreading the points further apart, I guess
