Have had 2 bad crashes with my last 2 flights. 1st crash been flying on the 3rd battery then just a total loss of controls. Sitting at about 50 feet creeping slowly away from us, we're trying anything then it takes a nose dive. After a major repair job, all new updates, calibrations I's dotted T's crossed, out I go again, compass cal. start-up, warm up good to go, nice easy flight out about 40 ft. high 500 ft. out coming back around 100 ft. from me it does a little wobble then takes a nose dive. This machine is about a year old many great flights except the last 2, last flight 19 sats 4mph wind clear skies ??? where should I send my telemetry data to see just what is going on with this unit? I will do the repairs again but worried about the same thing happing again. Any suggestions would be greatly appreciated.
