As Scott pointed out about the landing gear...
I had already found RC Universe by the time I started assembling my UCD.
I had read about the landing gear problems and some of the successful fixes.
Before I flew mine I reinforced the area with a couple steel rods...I think I used a couple short pieces of 4-40 quick links and a little epoxy. I fly off our acreage a lot and the grass is sometimes a little high and the ground could be much smoother (I plan on rolling it next spring).
So far, I'm knocking on wood, no landing gear problems but I really try to slow it down and 3 point it.
Point is once you decide which plane you are going with do a couple searches here and read up on it as you are putting it together.
You'll find a lot of great advice!
