1/4 Scale Lama - REBUILD
Michael K.
ALMOST FINISHED! Phasing.
I am finally ready to get this bird in the air again! First, I'll phase the head. The next chapter will feature tracking the blades. Closing in!
LEAD OR FOLLOW?
During this step, I went back and forth on the swash follower/driver. People will say that the VARIO logo should be on the OUTSIDE when attaching the follower. Based on a stock configuration of the follower from Vario, this would make the "hockey stick" point down. What I experienced was a poor ball link fit when I pressed the link on with the Vario logo facing outward. The link pushed too far onto the ball stud and that made me concerned.
Before Joe Howard passed away, he would say "hockey stick up!" I never asked him why, but it's quite possible he experienced the same thing I (and others) have. I reversed the follower and the link snapped on normally -- logo IN. I'm going to run it this way. I'm happy to hear from others and I just wonder whether the logo out mantra we have heard for decades on pushrod links is not applicable to this particular part?

I’ve had links in the past were the logo goes in. I Ive always looked at the link and determine which side needs to snap. One side you’ll be able to get both holes visible the other will only have one. You never want to force the ball-link past the small opening. It Stretches and deforms the plastic.
I’ve had problems with vario drivers and well qc in general and decided to make my own driver using Diabolo driver parts and the main hub from vario’s like yours.
Would you share your techniques in a separate post? I think many pilots (including me) would appreciate have an alternative!
Looking good Michael!
