I had Baumann thicken the leading edge of the GTR blade for me. When I go play in the mud I put the thicker one on. If I'm running a load and need to make long runs, then stock goes on. By thickening up the blade (leading or trailing edges) You are reducing the RPM's your able to turn. So if your motor is not modded this may effect your performance more than a modded motor will see.
I played with the props & went back & forth to Baumann testing & talking with Louis and his brother who does the work. After all tests I found that the best performing prop was the GTR big blade. (no surprise there)
We even tested and added some pitch to a prop taking it from 11P to 12P. The modded motor was able to turn it but not at a high enough RPM. Some more R&D was needed. It would be interesting giving this prop to those that have heavily modded motors and see if they can hit 4000 + rpm's still keeping it below the rev limiter etc.
