Mostly going on others recommendations. We did fly with Nikk and liked it on his plane. We like the lightweight and like that its full castering. Now it comes with a lockout, you can lockout from the cockpit if wanted. We ended up getting a T3 and the Tundra lite. We thought the Monster Shock package included the T3 when we bought the kit, so we ended up with a tailwheel and spring we don't need. (The one that comes from kitfox. Alaska airframes) I need to post them in classified and sell them.
