B-Max
 
How much speed loss did people see when they changed from an xr bravo1.5 ratio to the b-max 1.3 ratio?

If you don't reprop it you will loose a bunch, but with the correct prop you will be back where you were before or more.

I went from a 30 pitch with 1.5 xr at 105 mph to a 24 pitch 1.3 b-max at 96 mph

I meant to ask is the BMAX a standard length or -2. I switched to standard length from -2 to see if i can get my BT to hook up a little better and be easier on the drives. I know that the BMAX takes a lil xtra hp to turn, so on a complete guess id say a couple mph lost anyway. :coolcowboy:

The b-max is not a shorty
