Default Wheel Pants

Hey Everyone,

Recently picked up an RV3B. LOVING it.

I have the dreaded shimmy. Tires are pretty far out of round/balance. Brakes are worn. I have a bit of work ahead of me. Thankfully the fear legs already have a wooden dampener.

Interestingly, without the wheel pants I have no shimmy at all. I have the "stock" wheel pants, they look... huge on this plane. The extra weight at the end of the gear can't be helping the shimmy, even if I replace brakes/tires.

What wheel pants are everyone else running on their 3's?

I have an RV6 but I am running James wheel pants. I assume you also have 500X5 tires, so they would be the same for you. If you put on new tires and balance them it should help a lot.

Our -3 has standard pressure recovery pants, and they work fine. One thing that can affect shimmy is tire pressure - for us, lower pressure reduces it, higher pressure enhances it. Short of a major rebuild of....something..that is a quick way to reduce shimmy.

Been tinkering with lower vs higher pressure. 25psi seems to be the best place for my current setup.

New tires and tubes are going to be on order after the holiday for sure.

Are the James wheel pants lighter? Narrower?

They are narrower, not sure if they're lighter. I installed the James cowling so I bought a set of wheel pants to. When I got them it was Sam James and his son making them. The business got sold the new owners are still making them and the cowlings.

Is the shimmy dangerous? I have it as well but I just slow down and it stops. I wasn't going to worry about it. I don't notice it at all on takeoff, only on landings when I use the brakes to slow down. It only last for a couple of seconds when on the brakes. I then taxi with no issue.
