I am soon to start building the Dumas Dauntless boat and I need to decide on the merits or drawbacks of counter rotating props. Also as It has 2 motors I will have to decide on Brushed Or Brushless and what size motor. I was thinking of a pair of MFA 850 or 800.

My take on this Is that Brushed will drive boat at Scale speed cheaper and with less equipment IE cooling, 1 ESC Instead of 2. Plus acid lead battery will serve as ballast for such a big Boat 49 1/2 Inches.

I welcome any thoughts on this subject as I have not committed to anything yet, If my thinking Is flawed please tell me.

Regards and thanks Glyn.
