Right update! Managed to get the duck out on the lake even if there was a surplus of ice to contend with!
She sits very low in the water but then there is not a lot I can do with that! (Or more like I put too much filler on the bottom but i want to move on to the next project!!)
During the test run the motor kept cutting out and I'd loose all control.... tried replacing the ESC and the reciever no joy. Replaced the motor and all is now good
Going to have another run in the morning all being well!
