Decent below MDA, Legal?

if upon
reaching MDA, still in IMC, you cancel IFR (very quickly!)
then you would still be legal.


No.

In uncontrolled airspace, I believe you still must be on an IFR flight plan to
operate IFR. You just don't need a "clearance" since no separation is
provided.

I'm away from my FARs right now; I could be wrong (and will no doubt discover
it quickly if so

No flight plan is required to operate IFR in Class G airspace. You can't do
what is suggested here, but not for lack of a flight plan.


§ 91.173 ATC clearance and flight plan required.

No person may operate an aircraft in controlled airspace under IFR unless
that person has --

(a) Filed an IFR flight plan; and

(b) Received an appropriate ATC clearance.

Untrue. No plan or clearance is requred.

But you are still IFR (as others have pointed out) and the rules for minimum altitudes
(either in general or on approaches) still apply.
