I have a question because ive tried to contact 3dr and im getting no where. I havent flown my solo in about a year. emailed 3dr robotics asking them if I would need to do anything to drone since its been so long since last flight. They told me nothing was needed just check for updates, well solo was up todate all seemed fine. Went to start up and noticed only three motors were on so I shut it down. Started it back up and all motors were spinning gave it up/throttle and it went full speed and flipped, no damaged so little confused shut it down restarted it but this time I put my hand on battery holding drone down gave it up/throttle and again it went full speed but I held it and shut it down. Not sure what to do at this point dont want it to fly away and 3dr seems not to care I guess. Any suggestions paid a lot of $$$$ for this.
