Hello,
to all Lancair pilots.I am trying to install a UMA flap position indicator in my LNC2,but have some problems.
Here is the e-mail I have sent to UMA Instruments and their answer . In short it means "help yourself" .
As I suppose some Lancair owners have installed a UMA flap indicator in their plane,did you get such a problem and how did you solve it ? Sender P/N is 1H1 and indicator is a 1 1/4"
Many thanks for the answers .

Hello,
I'm trying to install a UMA flaps position indicator in my Lancair 320 I follow the instructions provided with the instrument but don't succeed in having a correct information on the indicator. With flaps up,I adjust the transducer to have 0° on the indicator.Then,I set the flaps down (40°) and the indicator says 5°. I turn the small screw on the indicator to have 40° indicated,then I retract the flaps and the indicator says 20° and cannot have something better than that.The transducer's rod is directly linked to the flap motor bellcrank . That means when the bellcrank and the flaps make a 40° movement,the transducer's rod do the same. But I am unable to see the right indication on my indicator!!!! Can you explain me what's wrong ?I suppose I am missing something,but what ?
The transducer MFG P/N is : N 0911000401000,S/N A 1218; the position sender MFG P/N is 1H1 ;S/N A 401
Thank you for your help.

Alain, That unit requires some playing with. You must make sure the actuator rod is giving the most possible travel and that its position on the shaft of the sender pot is proper. They have been used extensively but are not easy to set up. Disconnect the unit from the bellcrank and turn it by hand to see if you can get the range you want then you will know if it capable of working. Ed
