Hi Pondweed
The job was to design a set of running gear that would work, and be reliable and efficient, good running time, good access to the works, and the basic system to fit later models in the range.
Keep to scale appearance as near as possible.
A single screw, (2 channel cheapest )
B. Twin screw linked motors, 2 channel
C independant control, twin screw 4 channel
E. full house, three working screws. multi channel
we have done all of these in order.? model has now gone to the customer to finish off
Not sure if you follow the thread, we never made the shafts larger, we kept to 2mm, it was the new boss on the ends that was a special product as part of the shaft. the props were specially made to fit the shafts, and to be scale,
and you can not "tweek" a cast brass prop, you have to make and cast new ones, increasing the revs will achieve little in such a heavy boat, just overload the motors, and the props have to work at the best speed, as do the motors.
and the chances of anyone "tweeking all 9 blades to exactly the same angle is pretty remote.?
What clear plastic turret ?
