I thought the original question was about inverted "V" engines. While
the LOM and Mikron engines are excellent products, they are inverted
I-6 and I-4 engines, not a "V".

Bootstrap a couple of them together! ;-)

Didn't we discuss an old US tank engine in here? It was 5 or more
engines geared together. Lots of unique engines in tanks, air cooled gas
radials, 90 degree "V" diesels, etc...

BTW, neither the LOM or the Ranger engines suffer from 'hydraulic
lock' which seems to be mostly related to P&W radials. I owned a
Ranger inverted in-line 6 which powered a PT - 19 and it never even
smoked on start. I also flew a Zlin with a LOM I-6 and it didn't give
problems.

I think the inverted engines allow a nicer looking cowl and they do
improve the pilots visibility forward and down.

Yep...
