Hi ian,
I’m glad you’re resurecting the Wave princess, it’s one of my favourite boats from the 70s. I think you’re right about going electric, there are few places to run an ic boat these days, a pity that.
There’s a topic on here titled ‘precedent huntsman’ with a good discusion about motors and batteries that I think applys very well to the Princess and should be a great help.
As for the old Waltron gear, if it works reliably I don’t see why you shouldn’t use it.
But the key word is reliablly, I was never a fan of the Waltron, and modern 2.4 gig gear is very cheap. You might put the Waltron on e bay, I should fetch a few quid from a collecter.
Keep us posted on how you get on, a few pictures are always appreciated too, And keep the questions coming, this is one of those things many of us enjoy reading about.
Charlie.
