As I recall the Midwest ME 109 was a stand way-off scale model. I never built one, but it seemed as you say - blocky.

I have built a couple Midwest kits and they were pretty average kits. Not the greatest die-cutting, but they were simple, built up easily and flew pretty well. The planes were fairly conventional and based on well-proven sport plane parameters.

Why not scratch build one from plans? It isn't hard to do. Contact Flying Models, Model Airplane News or RCM for plans or check out some of the plans services.
