Default Futaba 14sg lockout

Last fall I bought a very lightly used 14sg transmitter in " like new low time condition". It was purchased to replace my old trusty trouble free 9C transmitter and to outfit my squadron of planes with the new (to me) 2.4 technology🙄. I installed 617fs receivers in a 1/4 scale clipped wing Cub and a small 40" span Edge 540. I flew both of them 4 or 5 times apiece with no problems. I just recently bought a new R 2000sb receiver for my 50 cc Slick 540. While programming and setting up
throws, mixes etc the screen went into a strange unreadable scrambling flickering mode. I quickly cycled the on/off switch and the screen returned to normal. After the reboot everything seemed to be working normally again. I finished all the programming and went out for the airplanes new " maiden" flight a few days later. I did the range check with the reduced power range check feature and I got a good 50 paces with full control. Back to the pit for startup and runup and at 3/4 throttle all controls functioned as they should. Takeoff went smoothly with maybe 3 clicks of right aileron trim and I began with some basic IMAC maneuvers in a close in flight box. At the end East end of thetbox I did a wide 360* turn to approach the runway for a fly by. At that point I lost all conrol of the aircraft. The plane started a tight spiralling turn losing altitude fast but circling closer to me at about 50 yards away and at about 2/3 throttl. I was slamming sticks on the transmitter every which way and somehow regained control at about 20 yards away at about 20 feet from ground. Cut throttle immediately and glided in for a landing. Long story Long, I sent the radio and receiver into Futaba service a few weeks ago and got a repair price quote. I basically sent in the same info posted here and the tech said based on the info I gave of the near disaster I would need a new PCB board, RF side and screen. About a $200 repair. So my $375 purchase of a slightly used like new Transmitter will now cost $575 plus shipping and insurance costs. Ouch.. Really just wondering if there has been problems like this in the past with the14sg radio. Not sure how my comfort level will be going forward with this "new" replacement system and the rest of my refitted squadron of aircraft.

Sounds like you got one that was used harder than you thought. Spend the money get the radio back to 100% and go have fun. This sounds like a specific issue with your used radio. I never buy used unless it has been factory checked first.
