Here is my latest design the Acorn!

It has roots in the Nutball, Delta Nutball and Simple Delta. I designed this as a windy day flier and have flown it in winds up to 12 mph with gusts to about 18. I can get it to hover for short periods of time (I need more practice). It rolls well and will do tight inside and outside loops. It's a blast to fly.

The fuse is the same I use on my Nutballs. It has the down and right thrust angles built into the design. I've included it in my plans, see below.

I buillt it out of spare parts I had laying around, so it could be built much lighter, which might improve my ability to hover. It's a fun plane, so I've included pics and plans for everyone to enjoy.

Specs:

Wing span: 22"
Length: 22"
Area: 352 sq. Inches
Motor: 1700kv Blue Wonder (any Blue Wonder will work)
Prop: 8x3.8
Esc: Tower Pro 18 amp (What I had on hand a 10 amp would be plenty)
Receiver: 9 gm, 6 channel
Servos = 9 gm, qty 2 (5 gm would be plenty)
Battery = 2 cell Lipo, 1000 mAh, 20c (a lighter battery would be better)
No landing gear
Auw = 8.5 oz.
Construction material = Dow PBIII fan fold...Continue Reading

My latest build project was a set of 22" Nutballs for my Nephew and Bro in California as a gift, and one for myself of course. I been meaning to build a Nutball for a while and have read most of the original thread.

I decided to design my own fuse, because I don't really like having all the gear hanging on one side or the other of a flat fuse. So I made mine a semi-full fuse with and open bottom. with plenty of room in the center for the batteries, speed controller and receiver even the bottoms of the servos are inside the fuse sides to help keep all the wires inside. Since I was building a three sided box type fuse I built the down and right thrust into the design, so no shiming of the motor is needed.

I have flown mine a few times now and it flies great as promised. I now have a new favorite flyer. Today was the second time I had a chance to fly it and it handled 7 mph winds with gust up to about 10. The flying was a little wild with the wind, but manageable. I flew it with an 800 mah battery and a 1000 mah, the extra weight of the heavier battery helped with the wind a little.

All and all I love this Nutball and I hope my Nephew and Bro like them too or I want them back. See the pics and specs below.

Presenting the BB J3 Cub. This plane was my entry in the BB Tribute Contest, but was not finished by the dead line. In fact it has taken me a 3 months since then, because of more pressing issues. The plane flys better than my 42" RET BB, I built this one with ailerons, my first. I have a vid of it flying for about a minute before the batteries ran out of juice and I hit a tree. Remember to always charge your batteries before you go fly.

Here is the vidio of the maiden flight.
