If it's the Clipped Wing Cub from WorldModels (if I remember correctly, that's what was in the advertisement of the one I bought from them) then let me blow off some steam about what "evergreen" might mean.

On second thought, I think I'll be calm.

Evergreen seems to be the name of one of the ARF "factories" in China. Apparently it's not the regular World Models ARF factory. Beyond that, I doubt they mistranslated a word. I think they meant to divert blame somewhat.

It's a model of a fullscale aerobatic airplane. It's recommended to use a 46size 2cycle. Mine started breaking down on the first outing. I thought the covering was just reacting to the sun. What was actually happening was that the aft fuselage was built with understrength wood in a structure that needed stronger wood than normal. The top rear of the fuselage was basically 3 sticks. They were "contest balsa" in my airplane. They needed to be at minimum, rock hard balsa. Spruce would have been sensible for at least 2 of the 3 sticks. The light balsa started giving up from just the loads that came when trying to see how the sucker needed to be trimmed. I ironed out the wrinkles. Never gave a thought that the structure was crushing so didn't look inside. You can't actually see the sticks anyway. When I started doing snaps, the balsa hit the fan.

It's amazing how little the ARF factory workers know about wood selection.
