Some more advice please. I have been running my 1/24 scale (36") Vosper MTB Mk.2 for the last 3 yrs. on 2x 2836 1200Kv outrunners powering the outer two shafts with the centre prop. freewheeling. Power is from 4S LiPo's the props. are 40mm., performance is good and the motors and Robbe Roxxy ESC's run cool. In an attempt to reduce the weight of the boat, I've removed the two motors and fitted a single 3548 900Kv V3 thumper to the centre shaft and will allow the two outer to freewheel (thanks gra2 for giving me the idea over 3 yrs. ago!). I would like to use the existing 40mm. 3 bladed scale prop. ( George Sitek) but as I am still pretty hopeless when it comes to motor/prop. compatability, I thought I would ask here first.
Thanks, David.
