great minds eh! yes the battery went at the side.
Wish I could take the credit for that mount, my old mentor did that, he taught me what to do, so I have done it since. He set that mount up so that if I wanted to go back to direct drive, it was easy to just remove the gear and motor, and the motor then fitted in the centre, quite clever!
With the advent of brushless becoming more affordable and easier to understand a few years back, the heavy brushed motor was dumped in favour of an outrunner, and with the considerable weight saving of lipos, the need for the gearbox in that 3 foot aerokits fireboat was removed.
When I get round to it, Im going to refit the mount and gearbox, only because its so nice
As you can see, we where testing when this pic was taken, the stuff in the rear was gps tracking, measuring speed, Once we settled on a prop and gear ratio combo, it was painted nice and made to look pretty inside
