I rebuilt t' crashed model. Avast! Added a servo system t' release rubber bands that prevent t' props from windmillin' on boost (suspected cause o' boost #2's crash). Ya scallywag! Added a better GPS receiver, ya bilge rat, mini M8N. It boosted NICELY, and at burnout I pressed a button t' make t' servo release t' rubber bands. Well, blow me down! Just after apogee, Throw Mode stabilized t' model in an upright hover. T' GPS and compass worked t' provide a solid Loiter ability, and also Return T' Home / Return T' Launch.
