bruce88123 is absolutely correct. That is why ARFs can be a little bit trickier to fix than a model that was built from a kit. With a kit, you know how it was constructed and I always keep the plan for future reference. With an ARF, you have to figure it out from the model. There are books in the library that describe how to build RC airplanes and how to make repairs. AMA's Model Aviation has had articles on just the subject. As well I'm sure you could find info online. My Avistar's wing was fixed so many times, that it really didn't make sense on the last crash to bring it back. I had flown that plane hard for three years, several bad crashes and many ding type repairs had been made. Each time I tried to make the repair as clean and as invisible as possible. Many times I wanted to buy a new wing set. A new wing set costs about $75, and a new Avistar runs about $99. I always opted to fix it. So I definitely got my $99 worth of fun out of it.

I really didn't need a trainer but recently picked up a Tower Trainer 40 at $70. At that price, a major crash would warrant just buying a new model. But I'll probably try fixing it first.

With any fix in front of you, determine if it's worth your time and money. Sometimes it is better to just get to the next plane. I really was having fun with the Avistar though.
