Ok so I was flying early, because my phantom fixed its horizontal gimbal issue (posted somewhere in the forums). I have a P2 v.20 with the new Tx. The new fx on the Tx Throttle Down and lock is supposed to make my Phantom go down at a steady level right? However when I locked it (thankfully a few feet above ground), the Phantom turned off. It seems to do this too when the Phantom is at idle mode on the ground. Throttle Lock (lever all the way down) and bam, Phantom turns off. Anyone experienced this? Thanks.
