Can't help it
Flying radial engines is fun and all but really does not help the career progression to the airlines all that much. You might as well be getting SIC in a piper sencia. True it is better than instructing but people get stuck there thinking that PIC in a DC-6 is going to get you on with SWA and it will not.
The airlines want part 121 jet pic. I would not waste your time here.
