Why NOT to try out a new boat in front of the public.
I took 'The Rat' to our local lake for a trial. The steering servo was backward so I promptly ran her into the bank at a fair speed.
Fortunatly it's a Specktrum 5 so just a matter of reversing the trim on the Tx.
There was to much weed to try her out properly but certainly plenty of knots with the JR 480's and 35 mm. 3 blade props. Bit noisy though, mostly from the motors and Huco couplings. Could be the speed controller does not suit the motors and is creating vibration.
Does anyone know of a coupling that is not a universal joint. I remember Ripmax used to have one with a plastic sleeve that was suitable for i.c. Probably long gone.
Otherwise I will try using the Graupner 480's that I have.
