Hi Josok=2C
I am not so sure about what you are saying. When I had early problems=2C I
applied a 9V voltage to it directly=2C and the blades stopped at minimum an
d maximum pitch automatically. I would have been very concerned=2C if they
hadn't.
When you say superfine pitch=2C what does that mean ? I assume that the bla
des have gone past minimum pitch=2C on their way to reverse=2C because of o
verrun=2C and the lack of mechanical stops.
I have the feathering option=2C which is handled quite differently=2C and o
n a separate circuit.
Regards=2C Karl

Woodcomp certainly never even pointed at the possibility. IMHO=2C if you p
ower the motor directly=2C you can spin the blades all around on ANY Woodco
mp. Until the motor burns out=2C which will be very quickly. As far as i kn
ow only MT manufactures electrical variable speed propellers with mechanica
l endstops. 3: The problems i encountered were because of non suitable micr
oswitches=2C diode and motor. The same hardware can be found in any Woodcom
p in flight adjustables=2C wether those are straight=2C reverseble or sail.
