well I've done the towing behind the boat, and all other ideas, I want a rc shark, well dorsal fin, it needs to go right left and forward, and dive the height of the dorsal, I tried many times to offer a commission build, as I have failed many times to do this, but never any takers, I would have thought it was an easy enough project for a sub expert, maybe not, its a mystery to me, maybe time to have another go
This is what I have, but it just did nose dives to the bottom and trawled all the weed up, or bobbed on the top!
