OS LA .46 Props
« on: August 03, 2010, 09:55:48 AM »
I would like to know if there are any 3 blade props that would work on the OS LA .46 engine for stunt and sport flying, I have been running a APC 12/4 and they work well but I keep ding them cause of clearance issues. Or maybe a shorter 2 blade with more pitch?

Hi Mike,

I've been using a MA 12x6 3-blade repitched to 12x4 on my .46LA Pathfinder, running at 8600 rpm seems to work well.  you could probably cut it down to 11.5" or so and repitch the tip back to 4" for more ground clearance.
