My new project is a 42" Cat. I'm running twin KB45-08XL motors on 5S initially, with 4" Stinger drives. Do I need 1/4" flex shafts or is 5mm OK? I'm having trouble finding adapters to go fron the 6mm motors to anything smaller than 1/4. Ideas?
Props!!!! I was thinking about X452's Is that enough or should I try some 3 blade X450's or larger? I'm really looking for ideas here from some with more experience than I! That should be plenty of motor for this boat to rip shouldn't it? How far should the rudder hang below the sponsons or props--any formula or ideas? My rudder assembly hangs back about 150mm to the leading edge which would put it about even with the prop nut.
