I have a used Hangar 9 Sukhoi SU-31 for sale. It came from the estate of a club member who passed away. I'm helping the family sell off his planes and parts. It comes with a DA-100. From the looks of it, it has barely been ran and maybe never. There are JR DS8411 servos all around and two JR MatchBox's. Plane is in excellent condition. Local pickup in St Charles, MO only. $1600. 314-406-4949.
