RE: Sig Sukhoi SU31???
Hi John,
I have one that I have not yet assembled. I bought it about a year ago. At the time there was a thread that dealt with wing failures. It seems that the early kits were not well constructed and the wings would break apart in flight. Sug was responsive and fixed the problem by going to another manufacturer and replacing the faulty wings. The new wings are super strong. I haven't built mine yet because I have been busy with many other projects. I hope to have it done by summer though so I can enjoy flying it. BTW, flight reports that I read indicated that it has great low speed characteristics.
