Hoo baby.... If you do put 3" tires on that sucker, do us a favor and post a picture or two.
I've got a mini-edge. It sucks. Blasted thing actually will hook a tire ON PAVEMENT!! It's cost me a motor shaft (and the motor is trash when the shaft breaks at the bearings) that broke, a bent motor shaft (same deal... trash), at least two screwed gear boxes, and one servo. OK, the servo might have just frozen in fear on it's own. After all, darn near every flight killed something expensive and mechanical, and I think it figured it was next and couldn't stand the suspense.
The carbon fiber gear legs on the first set of gear weren't very strong. The 2nd set seemed ok so long as I didn't try to take off from the ground...... grin............ or land fast........ "fast" as in,
"at a speed sufficient for the aircraft to remain airborne".
I've attempted to fly that dog off of a soccer field that's very closely mowed bermuda grass. That "green billiard table" was just cut a day or so before. On the landing, the wheels hooked something..... jeez, I got not a clue WHAT...... and that pig dug it's cowl into the grass (and that balstedly beautiful egg shell cracked like a.... well, like an eggshell) and then flipped.
BTW, I left off the pants when I first assembled the thing and put on wheels that were 1/2" larger than the ones from the kit.
LOL, I had the same problem with my Mini Edge, I got it too rog & fly pretty well but not once did I ever land it gracefully!! I finally put it out of it's misery not too long ago when after a nice little display of a short hover pulled out of with a sweet looking knife-edge I promptly pile drove it staright into the ground.

Freeing up the speed controller, 4 new servos, & the 3-cell lipo for an Airfoil Z Yak!
