Hi, I am after some advice on motor size and Kv + Prop selection on a twin brushless setup on a 57" Apache hull Deep V. I am after a scale look to this build and like to run it on 6s if possible. I have the two struts and need to work out the distance to mount them apart to leave enough room for prop selection. I was looking at two TP Pro Comp 5650 1100kv but not sure if this motor will do the job, I tried the boat calculators but they don't give you a hull size to enter so I don't know what hull size they use for there calculations.

If you look at the drawing you will understand what i am trying to workout, eg if i make measurment A 70mm then i can use a prop up to 60mm with a space between the props B being 10mm.

Thanks

Anyone got any thoughts on the setup, seems to be a subject that no one knows anything about it.
