I haven't heard of any bj running a three blade props just two blades,
Then again there are alot of factors to consider, batt,motor size esc amps
prop dia and pitch, smaller props get you on plane faster but loose top end speed,
larger dia props alittle harder to get on plane but higher speed as long as it does'ent heat up your motor, esc batts to much.
I'm not sure but I think three blade props have a smaller thrust cone and not much lift, google rc props and see what you can find about this subject about 2 or 3 blade props on a cat 26 in long.
