Hello Fellow Pilots, I've a question regarding my Battery on my - Q 500 ! After charging my Battery, I inserted the Battery in My Q to take a Normal Flight on Sunday like I always do. Why doing my Pre - Flight check Satellites, Battery Indicator Light Bars etc. on my ST - 10 Indicate I had A full battery, As I took off and gained some Altitude, My transmitter gave it's normal alert of Vibrating that my Battery was getting low. As look down at the Controller there was no light Bars in battery section of the controller, as I hurried to land, Without a seconds notice, The Party was Over as I was flying over water, the Q Plunged into the lake with no chance of Recovering it. What would make the Transmitter Indicate a full Battery on take - off, then all of sudden, there is nothing with the flight being no more than 2 - 4 mins. ?
