Yeah I know what you are saying Peter, would of liked to run a 6mm carbon rod right through, but the holes in the outriggers are 3mm, and don't want to really drill them out as they are at an angle to suit the hull, If you look close at the photo of the inside of the boat you can see I have managed to get a screw in there on the rear outriggers, might do this at the top as well this will help the front outriggers flexing back, does that make sense?? Can get glue up inside the sponsons onto the carbon rod so dint think this will come apart, but don't want them to move after its been painted! As for the motor been told a Mega 22/20/3 would be up to the job, and need a esc of about 70amp, not sure what esc to buy, Feigao 80amp looks good for the price, but have learend buy my helicopter mistakes cheaper can run out more expensive in the long run. Keep your comments comming men, don't want to spend too much money as it will only get a rare outing for demonstration, but its got to be fast !
