All,
         Donny, one of the locals, suggested that I was over-propped and 
that was why my performance was off. (I'm running a 70" Warp 3-blade on my 
Rotax 582 with a 3:1 "C" box.) He suggested I go to two blades, or change 
the ratio to 3.47:1. Toward that end, I'm looking to see if anyone has a 
Warp two blade hub or some 3.47:1 "C" box gears that I might beg/borrow/buy.

Thanks,


Guy Buchanan

Not sure what aircraft you're using this on, but by way of comparison I have 
seen a 72" 3-blade Warp Drive used with 582 and C-box (3:1) on an Avid 
Speedwind. It worked well.

The difference may have been in the backtaper on hte blades, which was 
fairly extreme such that the chord length at hte tip was only about 1". 
However, Warp Drive themselves set this up. So it might be worthwhile asking 
them.

Duncan McF.
