Gasser Model RC Helicopters > Predator auto hub update

I'm still using 4 o-rings on top, and one on the bottom..I took out all height shims on the top of the sleeve...This left me with about .1 mm slack, I just took a socket, and punch the oillite bearing in a little more, since we have room, and took the slack out...
This raises the main gear even more..

How do I check for slack?
Just put the hub assembled on a flat surface, while holding the tail gear with down pressure, take your other hand,, and grab the main gear, and try to move it up and down...If you can feel but can't see movement, that should be fine..
I also clean the auto hub with contact cleaner, and didn't lube a thing..So far, this is the best its done.
I did put a little grease on just the orings.. update

I'm going to have to try this - my gear is right next to the frame, no clearance. It's not rubbing anymore but it's dang close.

...yep...

Get rid of the thrust bearing on top, and install a radial bearing while your at it...

I wouldn't run the Predator without doing these updates, especially the Condor...Smooth will be much easier to obtain...

Bill i only just remembered when i saw your post the details are as follows:

BEARING (1) 10X18X6
Part # CNBB1018
Cost $12.00


The T at the end of the above part# will represent the main shaft Thrust bearing which is of the same size.

The only reason for lube is to keep the parts from rusting. The clutch normally doesn't move except on the ground when you turn the rotors forward. Be careful with grease or oil on orings. They tend to swell and that will tighten everything up. Silicone orings will require a special silicone grease, viton orings will stand up better to mineral oil or grease. Just a friendly warning.
