Can I fly the wobbly prop and high perf on the basic temporary certificate or blue plastic card as issued to me when I pass an FAA Private check ride on an SEP?
Can I just walk up to one and fly it?
The temporary licence which the FAA examiner issues, is exactly that. It is your licence until the permanent one arrives in the post a few weeks later and you can exercise the privileges of it straight away (if only it worked like that here!!)
The FAA requires an instructor endorsement for constant speed prop and also for high performance aircraft. Once you have those endorsements, you can jump in an aircraft with those features and fly it - if the owner and his insurance company will let you
