We live in Bromont, QC, and the nicely paved runway is 5,000' long. Bromont is about 70kms due East of Montreal. I'm rebuilding my flipped-over RV-9A presently. It sounds like a dream trip.

I'd suggested tight wheel bearings. All other suggestions are really excluded by your case history. Got worse without changing gear legs, tire pressures or without having flat spots, etc. The conical bearings have a capability of tightening up, or not turning freely. Did this start after a re-lube of the bearings? The wheels really have to turn freely. One other thought on the mains, brake pads binding? I'm a believer in AntiSplat Aero's wheel bearing mod, and perhaps their balancing.

I made a spacer so that I could tighten the axle bolt without causing the bearings to feel the added pressure. It takes a few tries to get it just right, but when you do the wheel should turn as free as with ball bearings. The spacer makes the system much more stable. I made my spacer out of steel about 3/4 inch diameter. With the wheel off the plane you can measure between the outsides of the aluminum adapter hubs and then subtract their combined thickness for a first try at the spacer length. Start a few thousandths of an inch too long and the wheel bearings will be too loose. Face off a couple of thousandths and try again until its just right -- just a little or no play. There is nothing wrong with the AntiSplat ball bearing mod if you want to spend the money. I'm poor! Dan Hopper RV-7A 766DH Flying since 2004 -- only nosed it over once! That (and seeing the result of a couple of other accidents) made me a believer in the anti-splat gear leg brace. Great invention! Be sure to watch the videos on their web site.

We have gleaned a great deal of of good info that we will apply. It seems every trip requires a good excuse to get it started and ours is the Air Cadet League of Canada are having their AGM in Prince Edward Island the end of June. What a great excuse to see one of the most beautiful areas of Canada. I will update the list as to how the trip unfolds. Thanks again to all.
