These hulls are not like any normal boat that will plane out on its own. They are designed to be "driven" by the pilot who has to constantly trim out the boat according to power and flight conditions. I say flight because the hull is designed to lift out of the water which is why it is porpusing so badly, and it will only get worse. The pilot needs to plant the nose back down by pushing down on the trim peddle, which pushes the long aluminum plate at the back down which lifts the back of the boat up. What this is actually doing is balancing the entire boat on the prop.

The prop is trying to push the boat out of the water, and the pilot has to counter that with the trim plate, which will level the boat out and let it come out of the water and fly. When you are popping out of the hole, as soon as the nose starts to come up, you need to set it back down. With the right power and prop angle, these boats will jump out of the water on launch. It can be scary the first couple of times lol...

Once the pilot has the boat trimed out at speed, they have to be mindful of the shutdown which is were 90% of the crashes happen. When you are under power, you are forcing the nose down, and when you get out of it, you loose the prop thrust that is trying to lift the front and the prop becomes an anchor and actually will try to lift the back end and cause it to slide. To counter the loss of nose lift at the cut, you need to let up on the trim peddle so the nose doesn't plant which can get ugly fast.

Get on line and watch some flat bottom drag boat races and watch how they control the pitch of the boat as they go down the track. They will launch out of the water, but then get the nose down and peddle it all the way down. When everything goes right, it is a lot of fun, I have lost several friends from it going bad.

Be careful..

Thanks for the explanation! Have seen many youtube clips and they are all flying nicely along the water Smile

Tried to trim, and i can get it to sit flat on the water, so i will test some next time Wink

When i go full trottle, high speed and then back off to idle suddenly i can feel what you describe regarding the "anchor"... Scary Smile
