I think the Berg receiver that has been recommended for the Corona actually does include something similar - an "averager" that filters out any momentary signal interruptions. Another testimonial here - after breaking a rotor blade due to a glitch, I bought a glitch reducer. Fantastic! No glitches so far, with the antenna in the stock position. The whole heli seems smoother (although that's probably from the tweaking it got while it was out of the air waiting for the reducer). For 10-15 bucks, I can tell it's going to save me much more than that in broken stuff, plus a lot more confidence.
