Jason what kind of bearing are you using on the bottom? Angular contact ball bearing?

The lower one is a deep groove, sealed, ball bearing. The specs of this bearing indicate it can easily handle the load. It's the impact loads and contamination I'm curious about.

Angular contact might be a better choice but a few problems prevented us from using those:
  1. Not available in the sizes needed.
  2. Very expensive!
  3. Not usually sealed.
Those are usually used for machine spindle bearings and are mostly ABEC-7/9 series. Probably a bit too precise for this application.

So far the Bearing is doing well, needs more testing to tell for sure.

Default Pre-order list

Thanks for the calls and posts from all of you that want the yoke. I do have a customer list started for the first batch. No payment or obligation required. Feel free to contact us, PM, email or call to get on it. Please keep in mind it's still in testing and is not officially going to be available at this time

Yes, the plan is to offer the complete package as well as all the parts individually.

I have had thoughts in the past about doing a similar mod to an existing tailwheel. My idea was to take the components of the bottom half of a mountain bike headset and turn an adapter on the lathe to make it work. They're sealed thrust bearings with seals.

Smile The "Wright" yoke bearings

Bob,
Certainly not a bad idea. Wouldn't be the first time bicycle parts were incorporated on a airplane.

I think this is a great mod and well worth doing. It eliminates having to stab at the pedals to get the tailwheel to break loose. I've flown one airplane with this sort of bearing incorporated which really improved ground handling.

It should, ours does. I don't imagine there will be many issues with this......But I have no control of the various tolerances on other forks. So we can't guarantee that it will.

Default steering arm

Why don't you guys rework your steering arm? It needs more play. Not enough slack in it. The spring is way to tight causing the tailwheel to be to responsive for crosswind landings,

Steering arm? I'm assuming you are referring to the Steering link? It's not intended to have "slack" in it, in fact the opposite is the point. If slack is what you are after then maybe the stock springs and chains hanging loose would be better. It's really a matter of preference.
