Aerofinn, your 125 sounds like mine.
Dan, this is an RCU issue as my iPad suddenly shows fonts as almost too small to read. I've sent a couple of messages about it and was asked to test the button navigation problem.
Low idles are nice if they are reliable. I have a 72 that would idle at 1900 with a good transition. But, I sometimes sit and do touch and gos and it did die on me on an approach, so I bumped it back up to around 2100 rpm. W8YE has a 56 that you couldn't even hear when he did approaches. He wouldn't tell me how low it was, but I would guess much lower than my 1900 rpm. His never quit and he sat there and did tank after tank of touch and gos as the sun went down.
The 125a has its own personality as compared to other Saitos.
