having ago at measuring up my belt cp servo arms?

[liambaker996]

well i think i am going to have a go at measuring up the arms how do they need to be?
once they are measured up think that all needs doing then is triming and the pitch
but yes you guessed it i have no pitch gauge i cant believe it
thanks best reagrds liam

cant really do it by rod linkage lengths - i tried it that way

you need to unplug the motor and put all the trims except the thottle trim in the middle. keep the throttle trim at the bottem.
then put your throttle to mid stick with the motor still unplugged.

make sure the servo arms are at 90degrees. if they arnt then take the arm offthe servo and put it back on at 90. do this for all 3 servo's.

the servo arms are then connected to an L bracket on the belt cp. make sure all the L brackets are at 90degrees aswell. do this by changing the rod length from the servo arms.

then from the L brackets there is another set of rod linkages that connects to the head. the blades should be at 0 pitch because you are at mid stick. if they are not then you need to alter the upper linkage rods from the L brackets to the head.

then you need to check that it movers free through the pitch range (bottem to top stick) you should get about -10 at bottem, 0 at middle and +10 at the top.

now my brain hurts and i need a lye down - cya
