Not exactly what I'd call definitive, but it's fun...



Be interested in hearing if the Re-imagined 152 has the Sparrowhawk Conversion Standard. That would account for more of the climb and speed differences than stock. I've found that the stock 152s are just heavy enough to make the added HP a non factor. The Sparrowhawks however are cranking out about 25% more power than the O-200 and it shows.

My understanding is that the "reimagined" 152's are NOT Sparrowhawk. I had LyCon build my engine for the Sparrowhawk Conversion on my Aerobat last year and I had them do all their magic. It Dyno'd a 148 hp at 2800 RPM on the test stand which is the new red line with the conversion. It is a sweet flying little airplane. I just wish the Sparrowhawk Conversion added some additional take off weight

adding to the answers to Joseph's question-
the 152 is 28 volt and has primer ports in all 4 cylinders. starts a bit easier I think. there might be a bit more shoulder room i'm not sure if that is the situation to all 150 model versions though.

The doors were "bulged" on the 150 in the mid-1960s giving more shoulder and elbow room. (It's only a few inches, but quite noticeable to me.) After that the cabin size did not change for the 150 or 152.

The odds of sticking a valve are much less, but they still do happen. I'm pretty sure Alan Core mentioned it during his maintenance seminar on un-sticking my stuck valves that he'd seen it happen, though not as frequently, on O-235s and O-360s.

I could be mistaken though. I had so many conversations about stuck valves that week, they all kind of just ran together.
