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