This is what the Fiat A.74 engine made from the Yahu Models kit looks like before being put together. You can't see it in the photos, but there are pins and holes in the individual engine segments to make it easier to assemble correctly into a whole. A very cool addition is the nameplate, one tiny one for the engine body and a larger one for use on the stand, for example. The second photo shows the motor already assembled. I can't see it on the photo, but there are some notches on the shaft coming out of the engine, in case someone would like to make a ‘Fiat’ with the propeller removed. There are two engines, but there will be several of these Fiats built.
p.s. Editor I have to finish the Fiat G.50 x 2 both in 1:72, the Curtiss A.12 in 1:48, the Ki-61 in 48 and the Mc.202 in 1:32 so the Ca.3 will be in the workshop in September. I would like to do it in an interesting camouflage but I don't have the materials so if anyone would share the material I would be grateful. Although painting the canvas itself is also quite a challenge. I still have some time to spare.
