I added tail wires, and a little balsa on top of the elevator to give the plastic somthing to hold to. You should add a small ply plate to the tailwheel attachment point.
On my first flight I was overanxious, My wife held the plane during starting and pushed down on the tailwheel, the screws started coming out. I figured I could fly without it. HA! it was windy, the plane went full speed into the warning strip ( taller grass on the side of the runway) and ripped the LG plate in half.
I epoxied it on at home and the plane flew fine for 6 flights and the plate broke again on a deadstick.
I replaced the plate with some contest grade aircraft ply and never had another problem.
The problems were of my own making, yeah better ply would be nice in the LG area but under normal use its fine.
I do reccomend the plane, I still have a 66" edge, it makes me look smoother than I am.
When this one goes in for good I will get another ( on sale).

Now if you want to talk about a poorly engineered, POS LG setup... think WACO. ( not kange's)

OK here is a negative. The wheelpants s!ck. Toss em!. I fly off grass now so I dont care. If you want nice wheel pants look at sig kits.

Just an afterthought, I used a tailwheel from a rascal. The stock tailwheel my not need reinforcment.
