Thank you, Vladimir! The engine in the Roden kit is much better, as well, although it would still need a bit of work if I were leaving the cowling off. I'm using your lozenge on the undersides of the wings since that is the only place the lozenge is exposed. On the fuselage, tail and upper surfaces, I'm using some old Eduard lozenge since it will be painted over.
Cheers,
Bud
