Just checked eBay $10.99 shipped! Also looked at battle and see the series I mean to use are available in 3 sizes with just an increase in width. Don't know if more than the 7ah is needed but the option is there. Thanx for that tidbit! GJ

Great post Nas. I was a mechanic at the U of Minnesota for 34 yrs. Among my myriad of duties was maintaining battery powered 3 wheel carts for the miles of steam tunnels 100 feet below the campus. Every week I'd top up the cells of the size 27 car batts. There were a pair of 12v chargers for each cart. Battery attrition was high due to the heat-someplaces 140F. I'm a new oldie here and am moving forward on a ship whose hull was built 10 yrs back. Have no experience in RC so a new learning subject. As with any field you web folks are the goldmine of info for us nubes. Thankyou,GuzziJohn😉

Thanks guys,I too have been looking at the aircraft belt drives but don't know anything about them. I'm thinking this Johnson motor is of the numbered motors family I see referred to everywhere so perhaps it would bolt up. I'll try to add some pix of the boat's progress soon. GJ

Hi, I'm a retired mechanic just Into my 1st attempt at an RC ship. It Is a 1/96 of a 716' Ore Carrier. I have a 60mm 4 blade Graupner prop and am clueless as to what speed It should turn. I have a 540 size 5 pole motor that Is rated @ 6600 rpm w no load @ 12v and wonder If a reduced ratio Is needed or not. Thank you,John Pierson-Champlin,Minnesota
