I also have the RV6A nose gear on my mkIV. I've contemplated cutting the side plates of the wheel frame in such a way as to weld them back on inverted to gain clearance for the prop and steering pivot point. Might be an option to think about. At this point I'm probably going to convert to taildragger though.
I recall Trent Palmer discussing in his videos last year (possibly the year before?) he and/or his cohorts had significant number of flats and they were moving the other direction. Perhaps the Alaska vegetation wouldn't be as hard on them???
Third year for McGregor. First time I saw that video above too, I'm doing a "high speed" pass in the trike on skis at 26:00. Can tell it's high speed because the skis are normally at very happy angles but go into aerodynamic braking mode at high speed. Also, if you listen closely you can hear the auxiliary jet engine whine. Iirc it took me three hours to get there, think I was the last or next to last, 105th to show up. They had just finished giving away door prizes.
The Avid is parked for the winter but I have the skis mounted up on the trike. I was hoping to make it to the Jackson ski plane flyin at McGregor last Saturday but I don't care to do subzero temps in the open air anymore. Hoping to get out on them tomorrow for the first time this winter.
