Jim,=0A-=0ARecent experience and observations with a different type of co
nstant speed prop controller not going back to fully fine has persuaded me
to ground our aircraft, remove the offending article and replace with a dir
ect switch control unit with only manual control.=0A-=0AIf you get stuck
in coarse pitch and the constant speed unit is saying you are fully fine by
steady light or other means you could end up over-running your landing str
ip ,with no go round option.=0A-=0AWe check full take off /climb revs are
achieved- as a landing check.=0A-=0AWhen doing our testing we found th
e prop would re set to fine pitch when the avionics were switched of and ba
ck on.=0A-=0AThen on one test it failed on that mode.=0A-=0AFurther inv
estigation showed that switching relays were not completing the circuit, ye
t could be heard to be clicking.=0A-=0AOur teams skills and knowledge cam
e to the best solution for us and our planned use of the aircraft was to bi
n the electronics and go with a simple manual switched unit, and ground the
aircraft until it arrives.=0A-=0ARegards,=0AConfirmed Ludite,=0AKevin=0A

st message posted by: "g-fizy" <jim.davis1@me.com>=0A=0AHi all i am having
a few problems with my pv50 prop ,it does not seem to move ,take off is ok
but as soon as i start to get to about 500 ft the engine speed seems to go
uncontrolled ,the controller seems not to be doing anything =0Ait displays
a change in pitch but i do not think- that the actual prop pitch motor is
moving , the smart avionics- controller manual says you can adjust the p
rop with out the engine running ,I am guessing that if you put the controll
er in manual mode and adjust the- pitch the motor should move,but nothing
happens ,please can some one confirm this ,as i dont fancy fault finding w
ith a spinning prop ,or has anyone got any ideas on fault finding .Please l
et me know =0A=0Athanks jim=0A=0A--------=0Aowner g-fizy=0A=0A=0A=0A=0ARead
