AM, I'm very impressed with Futaba's commitment to address customer concerns and suggestions. The expediency and speed with which you are able to sort out the genuine concerns from the sea of frivolous complaints are equally impressive.

Just a couple of days ago, I was thumbing through the Mouser catalog looking for replacement knobs. Here you are beating me to it. I might still get the knobs I prefer anyway, particularly because I like to get ones that indexed (i.e. numbered). This may be a long shot, but you don't happen to know what size shaft these knob fit on, do you? 1/4", 1/8" or 6mm?
