Main Gear shimmy
I thought I would ask if any of the flying RV-10's are having any of the main gear shimmy we have seen on the other RV's. I am, and it's driving me nuts (no comments about it being a short drive, please). It appears to be getting worse, so I'm thinking it might be the tires. I've rotated the tires, and put the wood dampeners on the main gear legs as well. It is very pronounced upon landing and decelerating through 32-34 knots. It is hardly noticeable on takeoff, probably because we accelerate so quickly. But upon landing, it almost wants to shake the airplane apart. It's fine faster than 34 or slower than about 28. I have verified it is the mains by having another pilot stand outside the airplane as I went by with the shake occuring. It is only noticeable on pavement. I fly off of grass 90% of the time, and have about 500 hours on the original tires, which are still showing about 1/8" of tread, deeper in the middle, and shallower on the insides and outsides (due to rotating the tires). I've had the right main brake line fail at the fuselage joint, and I'm thinking that it is most likely due to the shimmy.
Thanks in advance.
