Complaint about the MAN!
Not a good case in point!
The Sig Sukhoi is a nicely done ARF that flys exremely well and did not experience "hundreds" of wing failures. It was more in tune to a dozen or so out of one thousand plus kits.
The overall quality and parts fit of mine was 98% positive, flyability excellent and capable of more than my flying skills. I saw over a dozen fly at various fields and fly ins and no owners there had any complaints.
The folks at Sig took care of me by sending a replacement fuse/tail kit at highly reduced cost (after a few good phone laughs) after I tripped and fell on my newly finished Sukhoi!
But once again, this is a single persons opinion which happens to coincide with the MAN review.
