I never said anything about stopping progress - rather that one must be sure that additional "features" are progress in the sense that it improves the overall reliability of the system - in this case, the RC link between pilot and aircraft. Dual links, better antenna technology, telemetry, etc. are proving to be progress in that regard. Adding an autopilot with "go home" capability, so far based on experience in the quad/hex community, not so much...

Your milage may vary - as in the case of stab. balancing...
