What do u mean by chatter region, some kind of resonance frequency ?
"Bart" wrote in message ... On the Jet Ranger you can engage it under 38%, at about 6% it makes an unnerving chatter that I never liked. According to people at the factory you're just supposed to fully engage it under 38%, no pussyfooting around. I usually disengage it at low RPM and let it coast to avoid the chatter region, then lightly re-engage it just to stop the blades 90 degrees abeam so I can throw the tiedown over them easily. I know one thing for sure, the damn brake pads are expensive. I'm sure they're really just some stock automotive part, but you can count on spending 10x more than the Napa equivalent. Your flight manual should describe proper operation, but since brakes are usually an option, it might be in the supplements section.
