A Lawrence three cylinder. That was a great little airplane. It would have been fun to build and to fly one of them.

I'm trying to convince the wife that a 336 is a good idea. (I'm trying to convince myself a 336 is a good idea....) The O-2 is one of the cheapest ways into the Warbird world, and is still a practical plane. https://www.cascadewarbirds.org/2018/07/01/for-sale-cessna-o-2a/
I have a solid aluminum model of the DH.88 somebody carved out of an aluminum billet. Have one of the P-38, too, made the same way. Must have been a chore to make. Found both in small shops in the UK.
WOW! The relative scale between the fuselage/floats and the engine/nacelles is striking! The design gives an overall impression of low aerodynamic efficiency.....
Hard to see in that image, but the S.55 was a push me- pull you aircraft like the Do.335. Pushers usually were much higher drag than equivalent tractor aircraft, Do.335 excepted. Image Unavailable, Please Login
Apples & oranges perhaps, but would that also hold true for a more modern design such as the Cessna 337?
See the man for scale - this pic shows 2-blade prop pulling and 4-blade pushing. Other engines/props were used on different models. https://en.wikipedia.org/wiki/Savoia-Marchetti_S.55 Image Unavailable, Please Login .
DO-335, I read that it was almost as fast as a P-51 with just the rear engine running. More efficient prop stream.
