RE: Gyro for trim tab control?
Hi Dean,
If you're going to try this in a medium speed scale build, it may be worth a try, but you may be right as to the correction always being a bit late...
The faster you go, the more the correction will lag behind, possible making things worse in terms of riding attitude.
If it's a fast electric; trimtabs are a bandaid for a poor set-up, so don't bother, just get the set-up right.
Another option might be to adjust stabiliser fins , sticking out of the hull like on the Drumbeat of Devon.
