Pusher Sportster (oz7425)

About this Plan

Pusher Sportster. Free flight sport model.

Quote: "So the Pusher is officially done. But after all the scaling & measuring, I noticed after I finished, the wingspan is 48" instead of 50", as per the plan. Once again things just don't add up, even though the scale squares are correct and the wood sizes are correct. But then again, this depends where you take your measurements from. Nothing is really very accurate on these drawings, as I know they never envisioned what we're doing with scanning and a computer!

I put in the correct measurement (text) on the plan, for the main wing spar which should be 1/4 x 1/2, not 1/4 x 1/4.

As for the center section, I'd reinforce it, maybe sheet it. In addition to that, at the rear on the outside of the fuse, I'd put some balsa angle stock to support the rear of the wing. It doesn't show it on the plan, but if you look close at the picture of the fuse, you can see the blocks at the rear. So there you have it, stretch the wing out two more inches and you'll have a "Fun Flyer" as Mr. Winter put it or be daring and fly the short wing version! (Or maybe someone else can correct the wing...I'm going to take a break from plan restoration for a while, to catch up on building)"
