Hi there.

I was wondering if you wouldn't mind sharing the dimensions of this plane that you build. Also, the degree of the dihedral angel you used to connect the wings.

My grandfather and I want to build this plane, we just need the specs.

Thanks!!

Hello,
please follow this thread on RC Groups. Its all about Nutball.
http://www.rcgroups.com/forums/showthread.php?t=836389
I made little changes according to material I have.
Good Luck. Happy Flying :-)
how much would it cost altogether to make the nutball
Transmitter - $25 - $2000
Motor - $10
ESC - $8
Props (5) - $4
Foam - $1 (dollar tree foam board)
Battery - $3
Battery Charger - $20
Connectors and misc - $5
--------------------------------------
Total - $76 + shipping and whatnot (as a total beginner with no other equipment)
Without Transmitter, Charger, and Connectors - $26

Nice build, but there are a few things I see that can be done more efficiently.
1) instead of cutting the wings separately, cut a disk and score the wing lines, fold them over a 1.5 inch surface and glue in the crack. this will give the correct dihedral without making messy cuts.
2) don't use tape for color, too much weight. Use foam-safe paint.
3)Thinner foam would be much more aerodynamic and easier to work with.

Overall good. I like the paperclip bamboo pushrods and landing gear. very economical!

Building an airplane is difficult enough even with fully detailed instructions. Once your Wordless Workshop contest is over, please come back and fill in the details on this. One of the huge issues that would be difficult to address wordlessly would be finding and maintaining the center of gravity as you attach the various pieces.

oh yeah, and the most beautiful thing with 'Nutball' is No Need to Adjust its CG !!!!
Yes, its true. Just attache those pieces together as accurate as possible and fly! This is what Nut Ball is all about.

It's not much of instructable if I have to leave the site to view the instructions. Why don't you put the instructions in the site as steps?
the merog (author)  Ilris3 years ago
hi, as I posted this instructable as entry for 'Phot only' contest, I am restricted with photographs only. But this instructable should explain everything well with pics only. So, if you have any question on 'hoe to' of something of it, please let me know, so I can add more pics explaining it.
Thank you.

Guys, my apologies. I entered this instructable in a 'photo only instructable' contest. So, it should not carry much text.
Umm you can access so much of discussions at the provided RC Groups link.
Anyways, if you have a question, just hit in here, I am always there to reply.

Great - A nutball on here at last.
I built mine last summer, but it was my first ever foam build and RC build so it was a learning exercise and I didn't take pictures for an Instructable.

You've got some great pics there so why not develop it into a full step-by-step guide?

It's a great starter plane both for building and flying.  As Goldguy (the designer) on the RCGroups site says - Mild to Wild. 

HERE'S a YouTube video of one.  (If you search, use the terms "nutball RC" or "nutball plane", otherwise you get . . .  err . . .  something else #;¬)
