Hello all. 1+ month owner/ lurker, now addicted (and my wife thought the fly fishing was bad) Ultimate goal is a river flight up the Chattahoochee near me. My experiences to date is of you fly out to marginal visual range and the battery power goes down (LED warning from afar) it seems to go down hard..is this normal? I flew it straight up the other night and killed the Tx...she seemed to float down fine but landed hard? Stock machine...recalibrated/ upgraded once...2000 m really ?
