Both of the 450's I flew had Covingtons on them, but the last one I was in had a geared 1340 from Aero, mated to a three blade Albatross prop. That engine had 140 SMOH on it when I started flying it, and it was a total workhorse! I can remember several times when we filled the hopper almost full and I could still get off the runway. I never once felt nervous about sitting behind that engine... I cant say that about the two Convingtons. Both of them would burp and stumble now and then, just to make your butt draw up and your mouth get dry! But, I guess that's just part of being a radial engine driver.
