Beefing up the landing gear area, merely causes MORE DAMAGE to the fuselage to occur on a hard landing!

You need to work on the PILOT first, to assure that you do not land the U-Can-Do too hard.

As suggested start with something else.

Save the UCD for the future.

Don't fly it until you are more confortable repairing ARF's as well.

IMHO: Once you learn how to repair balsa and repair covering, you'll be ready!

By this point you'll have a few light crashes under your belt and can take care of dealing with mishaps should they occur.
