On the technical side, can anyone tell me how the pitch works on the blades? Does the prop lever change all the blade angles simultaneously or is there something more complex happening between the two sets?
It probably involves a number of mice running on wheels inside the spinner 😀 .
Seriously – I understand both sets of blades have variable pitch control which works in a similar way to a single prop. There is probably a very good technical diagram which someone could post?
BTW – one feature is the fact that the two props are slightly different diameters, only a few inches difference. There was some unpleasant characteristics if they were all the same lengths. The props on 441 are of course cut-down Shack props.
