Watch the points on the lightning bolts on the wing, mine lifted a little when just giving it a quick going over with an film iron (a little clear UV stable tape fixed it)
As for your comment that for the price these are leaving you very happy, everyone else with one of their gassers tends to state the same oddly enough - even more so when the flight reports come in. It's nice when you find dam good quality at a more than reasonable price like you do with these fly model gassers.
My original 56" yak54 from them took a little work in the elevator, but was a fantastic flying 'little' plane when all said and done. While not flown yet, my 30cc sbach is proving itself to be in a league above the yak was based on build quality.
Best of luck with yours!
