Nutball for Nephew and bro

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.

Hi: I'm not new to fling, but it's been at lease 20 yrs since I had a stick in my hands.A friend of my told me to go to my computer and check on the Nutball. Well it got my adrenaline flowing. Who would think an electric motors on a foam dish would perform like that. I sure would like to try this brand of flying. Needless to say I have to start all over again. I know I can build the NB, but what do I need to fly it? I'd like to start small maybe 10" to 17" dish, what size equipment would I need? So please somebody help. Lou

Here is a link to the Nutball forum. You can find the plans and more info then you need there. The guys are all very helpful and will be glad to stir you in the right direction.

There are quite a few people that have built the smaller ones, so just go to the end of the forum and ask about the power system and I know they will help you out.

BlueFFF: I'm new at this rc group stuff and I got mixed up with who told me this and who told me that. I though you said to go with the 20", so I sent you a private message.
I don't even know if I did that right. So thanks for all the info you gave me, I will use it wisely..
Thank You Lou (DelcoLou)
