Weird defaults

I’ve got 5 different MR’s running Arducopter 3.2.1. Just setting up another but got some odd defaults in the extended tuning section. For example my imax for previous units would be like 500 pitch and roll and others like yaw and loiter would be 8 and 10. This thing loaded up with the usual .15 p, .1 I and .004 D for the rate PID’s, but all the IMAX setting are all at 100. So now I have old units running 3.2.1 with IMAX numbers way off my latest multi. Is it a new way of MP representing the IMAX values?

Same problem here. This issue seems to be the same as

Stange. I really hate change… No, just kidding! But I’d feel better with some explanation.
