Got the new parts nowOK, today I received the new parts.
Here are the new inserts with one of the stock inserts
in the pic for comparison (the new ones are 9mm longer
on the outer portion). In the foreground is a spacer
for the mixer arm mounting onto the grip.
Here is the feathering shaft I am using for this project.
This is the Raptor 60/90/G4 part and is 118.5mm long. The
stock shaft is on the left for comparison (approx 18mm
Here is a dry fitting. Note that the spacer between the
grip and mixer arm is less than the 9mm of the new inserts.
This will introduce a bit more correcting delta but at
the same time the feathering shaft is now more limited
in how much it can teeter. I'll see if the effect is
good or bad or not noticeable and can always add another
spacer and longer bolt.
Here's something I discovered when choosing bits for the
new head; There are two sizes of flybar control arms. I
didn't realise this. The smaller of the two is going
to give more deflection of the flybar and thus faster
response so I am using two of the smaller arms.
