I think I had one of the first few 58's from BME. Tom told me to go ahead and beat it like a rented mule, and I have. Heck I didn't even baffle it, which I do for all my gassers, will be working on that next.
A decent 24x10 at 7000 is monster power, something like 44lbs thrust according to Pe Reviers spread sheet. Since I don't own any 24" props I might try and stick a 26x10 on mine just for kicks.
