I have built a Graupner 202, and it weighs just over 6 lbs with an Irvine 61 turning an APC 12x7. 3D performance is not as good as my Capiche 50, but it does fly pattern style aerobatics really well. Saying that, it has plenty enough power to prophang and torque-roll, but is much 'snappier' when using lots of elevator. It also has a very high landing speed when compared to the Capiche, which can almost be floated down.
