Unpacked and set up my Typhoon H Pro system and charged both Tx and Ac. Booted everything according to instruction and planned to just take off, hover a bit and get used to the new system. (Upgrading from Chroma Blade) Lifted drone off, climbed maybe 20' and then it accelerated out of control across the road into a stand of trees. With the help of the crash emitter I was able to locate it up the tree and had to climb up to retrieve it. Fortunately the branches of the for tree acted like a net and impact was minor with only the camera mount popped and a broken landing gear. Only a $12 repair this time but I am trying to figure what went wrong before I go any further and I am not so lucky next time. After reading some fly away posts after firmware updates I am concerned about doing them and am certainly afraid to fly it a 2nd time until I know what the issues is.
