Why the Bueller motors? I need high torque at low RPM, plus they are only 1.9A under load. It is not speed I am after but enough grunt to shift 29 kg.
Motors & ShaftsIt seemed a good idea at the time., A novel solution to a difficult problem.
However . . .After three days drying I carefully lifted the motors from their air drying clay bases - and the bases crumbled like a packet of digestives that had been used in a warehouse football match. I am sure we’ve all had biscuits like these.
My build threads include failures as well. ![Crazy %%](https://www.modelboatmayhem.co.uk/forum/Smileys/Tug/cheesy1.gif)
So, I was hoping to avoid the more complex route, intricately shaped mounting shoes in two inch OD aluminium tube. It is worth repeating that with the complex hull curves, and four big diameter motors, traditional fixing brackets were out of the question. The front edge of the motors touch the inside of the hull.
Half circumference shoes cut from two inch alloy tube, notched for the lugs and ground to shape at the edge that touches hull. Shaped wooden blocks made to support other ends. Epoxied in position, then padded out with Milliput, leaving a central gap underneath for a Ty-rap to secure.
As you can see below it is all a tight fit, even with the XXL hull size, and occupies the last two feet of the rear of the ship.

I still need to finish moulding around the shaft ends through the hull, fit the “A” frames, shorten the shaft inners to suit, then fit the four 40 mm propellers.
