SIG SU-31 structural failure
Yes, that was my Sukhoi broken over the couch arm, I still chuckle when I recall that day.
I won't deny there have been some failures of this ARF but many were probably builder induced. That topic has been pounded already so i won't go there. The important thing is that Sig has stood behind all but a few complaints concerning their ARF's, even replacing some that were poorly assembled or grossly overpowered (based on first hand observation).
One only needs to read the posts here on RCU about ARF's to ascertain some folks will never be satisfied with any one of them. At this point, most ARF's are an exceptional value for the cost but the bashers, whiners and know it all's are slowly driving the prices up.
I have had a few ARF's that were marginal in quality but for the price, and as a long time modeler, I just fix it and go fly. They are still a good deal.
