    Prop size and speed
    Hi all, Many thanks for all the fantastic responses and info. I currently have a 7.4V S2 LiPo 4000mha, a
    15A Motor
    and ESC with a 1000kva Motor. The prop I'm using is a 2 blade S type 35mm. Apart from the Motor there is no weight up front in the bow, so can't reduce that much, but I am using a "heavy" servo at 68g in the stern, so will use a smaller less weighty servo. I'll try changing the motor to 30A 1000Kva with a 42mm S type 2 blade to see what difference that makes. I also need to re-grease the prop shaft as suspect that it was running hot at the high rpm and caused a bit of speed loss. I'll post a comparison video so you can see the results!
