I've been working on a cartoon cub for a few nights now. I'll put up plans once it gets in the air.

Adam,
Your Cub looks great. Are you going to give it an under camber airfoil, or leave it flat?

Thanks! I got it framed up last night. My intent was for it to be a sort of barnstorming aerobat, so I'm going to leave the wing flat for now. Should be pretty easy to mod the plans for an under cambered version for nice lazy flying.

Sounds fun. Have you ever seen the video of Martin Muller's Cub? He did some amazing flying with it indoors. I think yours is something in that direction. His had ailerons as well as flaps. I've toyed for a while of doing something along the lines of what Martin did with his Cub.

I think you're talking about the "fun cub," which is a super fun plane.

I really like wringing out high wing planes, pushing something like a cub or taylor craft right to the edge of it's aerobatic limits. I remember watching Stanley Segalla do the flying farmer act at Rhinebeck when I was 10 or so and just being in awe of his skill.

I got the cub done this evening, going to try to get a flight in down in the parking garage if no one is around 33 grams using the 4-site guts and a 150mAh cell. Still need to some up with something for the wind screen though.

Adam,
That looks super. Its just got to fly great. That's a very nice weight. What does the wing loading work out to be?

Good build, Adam.

Regarding windscreens, I use thin cellophane wrap: Thinnest from cigarette packets, thicker from greetings cards. Once your brain is switched into "search mode" for this stuff, you see it everywhere!

Cheers

Got a few flights in this afternoon, and it's awesome. Video shortly.

BTW the wing loading came out around 2 oz/ft^2

Well, I've gotten around to building one of these things. I decided to go with the same dimensions you're working with. It took a few tries to get the plans printed off at the right size, but I've got the templates cut and I'm ready to start cutting foam. I also managed to talk a friend out of an old, very beat up Parkzone Su-26m, so I've got a radio brick and won't have to scavenge from my Dynex after all.

Hopefully I can make some strong progress and get pictures up soon. Right now, I'm thinking of Sharpie color and Saran covering, although I'd love to hear any opinions on those aspects.

Mines almost done also, I'll post pics later today. I used Corsair blue MicroLite film. It's not what I was expecting. I thought it would be a translucent colored film like Saran wrap. The color looks to be prayed on and pulls of easily with tape and isn't very translucent. If I had blue saran I would have used it instead even though it weighs more. Maybe the lighter colors are more translucent. Also get yourself some cheap disposible Shaving Razor and take the blades out of them, you really need something that sharp to cut this stuff without tearing it.
