INSTALLING THE ELEVATOR DRIVE
-Cut a 15mm section of 3mm bamboo skewer and test fit it in the bellcrank seat located
inside fuse 4. Trim as required to obtain a good fit. Once happy with the fit, cut the same
length of 3mm carbon.
-Run a 3mm drill bit through the pivot point of the bellcrank to ensure the carbon rod will
rotate freely. NOTE- there should be no play in the bellcrank, any play will lead to slop in the
elevator.
-Cut a section of 1mm push rod and bend according to the diagram below. A
100mm
length
between the 90 bends is required.
- Fit the 100mm length to the bellcrank as indicated below.
- connect another length of 1mm pushrod to the other arm of the bellcrank, this end will
connect to the servo arm and need only be long enough to reach the servo. Its final length
can be adjusted later in the build.
