    FE experts Needed

    Hey guys- I'm building a 1/5 scale SwitzerCraft Baby Bullet as seen on the 152vo website. I'm planning to use an aquacraft 60 amp esc , 4s electrlx 5200 battery, on a modified lawless lower unit. The utility class of racers has a maximum yardstick value of 1,370,00 which is motor Kv (2030) x volts (14.8) x diameter of prop in mm x pitch (slope) . I'm wondering if another motor is indicated, 3s pack, and what props to try? I'm running the set up with a ABC 42-55 b&P on a LeeCraft 3.5 Tunnel hull I converted to FE recently and am getting 47 mph. I'm not sure what the slope of a 42-55 is. Any help woul be appreciated. The kit is amazing as to quality of wood, directions etc. Thanks G Ray HambyIMG_7341.jpg

    If you are planning on running 3S, the AQ ESC will not work.

          I'm assuming he is talking about pitch?

                That controller has a LVC that is set for a 4S pack....on a 3S pack it will think the pack is dead (basically the LVC will think the 3S pack is a really low voltage 4S pack and turn itself off)
