it's so bizarre hearing all these negative reviews. I empathize with everyone who has had a poor experience.
My experience with the DX3R has been perfect. No glitches, no lag time, no resets. Just pure, simple, interference-free running from day 1.
I'm running a newish B44 with a Novak GTB 6.5R + GTB speedcontrol, Hitec HRC36965S Digital Hi-torque/Hi-speed servo. I've had nothing but excellent results, increased response times, and ZERO glitches with the DX3R. I couldn't be happier. Hopefully, your experiences will begin to match mine.
Take care,
