2011 U-5 Graham Trucking Nitro Build..

If you look at slow motion video you quickly notice how far the model boats travel completely out of the water. Every time there's an interruption in the roostertail means the boats flying. Too much negative angle on the wing drives the stern down and sets up a blow over situation. Too much positive angle and the nose tips over like an airplane in a dive causing the boat to stuff usually doing a lot of damage to the cowling and wings.

The big boats may use the wings for aero balance because they have the CG a lot further towards the back of the boat than a good running scale boat. But the big boats also don't have adjustable struts. The reason wings were first used was as an anti-blow over mechanism. If the nose came up too high it exposed the bottom of the wing to the slipstream and that lifted the back of the boat and hopefully set it back down into the water. When the boat is at speed it has far less static weight because it's held up by riding on an air cushion and the wings have a lot of leverage.

Your first paragraph covers what the Bud owners were being told, not that they would listen. Unfortunately, others knew more than those that actually raced boats.

I wanted to do that boat but looks like a wrap is the best way to paint that. Ive opted for Hoss Mortage U10 on my new Moceri Hull View attachment 304371

it can be done..... i know a guy....

But Larry you work too cheap and that paint job would take some time and lotsa paint.

Just laying out the masking could take hours. Then again, I'm kind of looking at the same thing with a couple of my boats

Just thought I'd add in some progress shots... Getting almost there.. Some touch up. Graphics, then some clear and she will be ready to go!
