So I went on a little drive to Sydney and Canberra and back, and took the quad with me.
Along the way I made many visits and had to share the fun. Highlights were flying off Echo Point at Katoomba in the Blue Mountains and a run along the beach at Diamond Head, Crowdy Bay National Park.
Bit by bit I am getting more adventurous and learning to trust my gear. The gimbal is still pretty twitchy but everything else is (thankfully!) super reliable. I will try some different servos soon and see if it helps - apparently the Naza has issues with some digital servos.
