Yeah, a bunch of varied props on RV's from Catto, one of the most popular for spectacular performance, Prince carbon fiber, etc. We have a three-bladed Catto and exceed Van's numbers by several MPH.
I have an option for the rv200 prop from whirlwind due in December and would be happy to sell you the option I paid which would save $1000 of the listed price. We'd have to contact them to see which prop would work for you.
