I just finished up and flew my VQ Models Space Walker on Sunday......only quality issues that I found were as follows:
Some of the balsa seemed to be of inferior quality (small areas of sheeting were too soft), lack of blind nuts for engine mount and landing gear mount.....that's about it.

As far as flying, it flew GREAT. My only concern is how it will hold up in the long run.
Is it worth the money? ($160)....probably......

I've seen these on ebay starting at $100 and usually not going past $110. They're advertised as US Aero kits on ebay.....I was leery because I thought that these might be the older models that were out there before Morris Hobbies started distributing them.
