Ok the winner is.... nobody...yet.

This is my first gas airplane. The Mvvs 45 is supposed to have slightly more hp than the 50 DA. (5.2 vs 5.0)

So getting the larger displacement engine doesnt make sense unless it makes more hp.

I don't think either will under power a 16 lb yak. A friend has a TOC Yak with a 50 DA and it has awsome vertical.

Thanks for the opinions. I guess it's like what glow fuel to use. What ever you think works. If I could buy a new DA 50 right now

I probably would. Only because it's made in the USA. I'm not convinced either one of the two engines I'm looking at, is the better

choice.

I'll decide within the next two weeks. Maybe sooner since they shipped my Yak today.
