MM PT-17 Stearman (Version 1.5)

Okay, I finally got the plans built Stearman test flown today. After dodging a thunderstorm , the weather turned out nice. I am really pleased with how well it went. It flies well at a good clip, but can really slow down for some nice fly-bys.


Plans are posted on the first post.

Wingspan = 24"
Power pack = F

Yeah, that's how it goes with these old biplanes. You need to drop in a bigger motor or add a bunch of weight if you're not really careful on the tail design.

Also consider adding landing gear. It's a good way to get a bit more weight out in front of the CG.
I added landing gear and 1/2 inch to the front of the fuselage and still had to add 3/4 oz of weight inside the nose ( under the front poster board ) , but I'm okay with that..... It flies very well.
