Mine won't be delivered till this Friday, but I have flown one on Realflight a little. On the Sim I discovered that the Shoestring will enter a flat spin very easily, and is one of the few planes that will not self-recover by neutralizing the controls. You have to use opposite rudder and add some throttle just like an R/C model or real plane sometimes. Looks like the later versions of planes on G2 are getting more realistic
