I am assembling the Velocity 90 flybarless head. When bolting the two blade grips to the spindle, the blade grips are binding and do not rotate smoothly. I have checked that the damper spacers are installed with the step toward the inner grip bearing.

This seems to be a tolerance thing: is there a standard fix?
Should I take the damper bearing and sand it down to make it thinner?

Cheers,
Chris

make sure the radial bearings are seated all the way into the grip

Good point: The innermost bearings (the ones closest to the yoke) seem to be fine. But I'll take out the thrust bearings and with a bit of heat and a socket tap down the outer radial bearings.

Thanks for the suggestion!

Got some advice from customer support (prompt response). It could be the fit of the damper rubber in the yoke. This is true as they sit out very slightly.

I was told to assemble and go fly; that everything would settle in and to recheck. So, that's what I'll do and will report back once I get it in the air.

The head and links will bed in after a couple of flights, but I'm concerned you should not have a binding or any notchyness in the grip, make sure the thrust washer and thrust bearings are in the grip correctly and you should be fine.

Chris, do the grips bind when you pull out on both grips and rotate them? If so then do not worry about it. If not then may need to look at it a little more.

Checked the thrust bearings to be sure everything is assembled correctly. No problems noted. I also took a socket and taped the inner and outer radial bearings after heating the grips with heat gun. I don't think anything really changed.

Nothing is notchy now, just not freely rotating. I think the dampers just aren't seated as fully into the yoke as they could be and that this is preloading the grips.

I will test fly it and then give it a check to see if things have freed up as customer service mentioned. If it doesn't free up then I'll have to go to Plan B (don't have a B at this moment but will when needed).

agilefalcon. Dont know if you still following this but Im having the same issue on the 50N2. With the Thrust washers in I was getting a real bad viration in the heli. Im able to pull out on the blade grips to stop the friction. When I took the thrust washers out it would have a 1/2 mm play in the feathering shaft and run smooth but have a little bit of tracking problem. Have you figured anything out with this. Just took it apart last night and put it together and trying a heaver grease in the thrust bearing and keeping the thrust washers in and waiting for a part to fire it up and try it. Just was wondering how your heli was acting with the thrust washers in. Any vibration????

If it's not a challenge. It's not worth doing.

Just from my experience:

Loosen the grub screws in the head (do not remove just loosen), spool the head up and the blades will find their own center. Re-tighten the grub screws and fly it. Mine was also notchy and it was because I tightened the grub screws prior to making sure it was 100% centered. It was causing the head to load one blade grip and the other was totally loose.

Thanks for the reply. Do not have a grub screw on the 50 n2. Fired it back up last night after going through checking everything in the head and its shaking with the thrust washers in. Took them out and it runs fine even with the 1/2 mm of play but tracking still seems a bit off and cant seem to get it right. You can barely notice it. I think the heads too tight with them in and it cant find center. Checked the blades weight and there both perfect to the gram. They might be up to a 1/2 gram off because one of the blade tips more on the balancer. I dont think thats the problem. Maybe Ill try just putting one thrust washer in on the blade side that could be a 1/2 gram lite just to take up the slop. If that dont work then maybe Ill take a little rubber off the dampners or maybe I,ll just keep them out. Pissed off at this point. Just want to fly with the heli being as true as I can make it. We all know what just a tiny bit of vibration will do to a heli over time. Thanks again for your response.

If it's not a challenge. It's not worth doing.
