Hi guys, Just thought I'd check to see if any suggestions before I send my P3S back for repair....after many happy flights with no range problems I suddenly get no more than 20 meters either vertical or horizontal distance before I get RC signal lost and Rth kicks in.....it just goes from full signal to no signal. I haven't crashed and prior to problem I hadn't upgraded firmware. Since problem started I have tried upgrading to latest firmware, calibrating IMU, relinking RC unit, Calibrate compass (can't see what effect that would have on range though), tried different locations for flying but all to no avail, starting to think some sort of hardware failure. Any suggestions before I send off to dealer would be appreciated. Kind Regards, The Snowman.
