Looking for some help on upgrading the prop. The main issue I'm having is trouble getting it up on plane. Used to be ok, but with now with 3 batteries and loaded down, hole shot is poor. With the stock prop, I get about 31 mph (gps) at 5800 rpm. Top end speed is ok, just need to get up on plane quicker. Anybody have any recommendations? stock prop is 10.38 dia. x 13P

Thanks in advance.
