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.
