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!
Yes, its true. Just attache those pieces together as accurate as possible and fly! This is what Nut Ball is all about.
Thank you
Thank you.
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 #;¬)
