Hi Guys
Chris - I'm not really into boats, made a couple in the 80's,this was a one-off experiment, a technical challenge to see if I could do it, so I'm pretty pleased it worked. i think what I learned most is there is a lot to learn about propeller sizes and what the correct size should have been!
Steve - cheers, I think this wiring was about the max of my knowledge, any more items and I woud have been stumped.
Steve - thanks, unfortunately the pond has developed aleak somewhere and the level keeps dropping - my winter task is to drain it and fit a new liner. Not looking forward to doing it, it is bound to be a really messy, and probably smelly, job.
richard - glad you like it. I saw a reaaly cool version on the WWW, a chap had a third servo which controlled the front ramp and so was able to take it to the shore, lower the ramp and drive off it a radio controlled Sherman. I chickened out of trying to copy that.
