Having "done" the warbirds thing with Sterling in the '50s, and Midwest in the '70s, I was in the mood for a design not popularized previously, and the LaGG-3 caught my eye. It's somewhat larger than the others, but I do have a Brodak B40, from the first run of imports, still NIB, as well as a fair number of other 28 to 40 sized engines (the 25 to 40 bracket is the one I have the most of, especially if you count old iron engines like Johnsons, Torps, and Vecos).
The years-delayed reorganization of the house is nearing completion at last, and I will soon have a space cleared off on a table to assemble an ARF Tutor II, and after that, who knows what next. I've about decided to discard the ARF's fuselage, or to at least graft onto the rear section, a properly vibration-resistant front end, to suit whatever I choose for power, such as one of the V-51 Tigres I recently acquired.
Having read somewhere that many first-run B40s had problems, I might put off messing with that one, assuming a "someday" build of a LaGG-3, and use an FP 40, or a sweet OS Max H 40 I have that runs very nicely.
