I replaced the tail wheel with just a good ole hard wheel like a Great Planes or something similar - works great.

Main wheels - I just replaced those with Dubro low bounce wheels. Take note when you go shopping not to buy them TOO wide for the wheel pants. If memory recalls, they were 3 1/4 tall and something like 1.25 wide - still a little wider than the factory foam wheels but the closest I saw. Whatever the low bounce are... that's what I got.

Funny you should mention the main gear. I put carbon gear from GraphTech on mine and love it, however my engine ran a lean on me the other day which caused me to glide her down on a windy day so rather than whip her around to the paved runway (heavy crosswind), I just glided down to the grass. Well, what do you know but it the wheel pant smacked a bump and actually separated the fiber in my gear right by the fuselage. Somewhat like if you twisted it. Didn't break off... just separated. So... another set is on order for another 50 bucks. I guess I just like saving that 6 ounces or so.

As for the actual axles... no problems with those at all.
