Bigger is more docile... A low wing loading makes it float...
Often by going bigger you will reduce the wing loading, despite the model being heavier overall...
Its a matter of finding the right size that will suit your flying conditions, and how responsive you want the model..
For the blue wonder I found a 24" 3mm depron build was great... in fact that was my first build and that of my flying buddy..
Since then we've gone through almost every size up to 36" and down to the 17" in depron plus a few CF and film/fabric night-kites, and all have been great..
Its definitely the simplest, most fun per buck model ever

Looks like Josh & Josh are taking a look at the Nutball.

Flite Test - Nutball - REVIEW (8 min 39 sec)

Hi guys, after seeing the flitest episode on the nutball I want one to have some fun

I have a TowerPro Brushless Outrunner 2410-09 13A / 104W, 1147 prop, some 600 and 800 mah 2S batteries and 9g servos.

Will a 24" nutball fly well with this?

Thanks in advance

yes!!

Yeah it's funny, I needed a simply plan for a plane that I want to build for a friend of mine. I have a 2208-14 motor and an 18A ESC that I want to install with an 800mah 2s battery. I was looking through this thread and most people build these as light as possible with a smaller design. A 24" is what I will probably try for the equipment I mentioned above, as well

I will more than likely use a 9x4.7 prop on my setup.

i have had them all 17 , 20, 24, 26, 28 , and 30 . they all have there advantages , but for all around outdoor fun the 24" is it! fwiw and yrmv.

Great to know, thanks

But first you need to know the 'secret handshake'.

Hi once again.
What should be the target wing loading for the nutball so it flies like a nutball ?
Will 2.5 - 2.8 oz/sqft be ok?

Thanks

If you hit that, you will be golden for sure. Really, anything under 4 oz/sqft is good. Some overweight Nutballs have even been known to fly decently at 5 oz/sqft and beyond. But you have the right idea -- go light.

low wing loadings float the best..
Ive had big Nutballs up to 5ozsqft and 32oz + AUW.... these are good in outside windy situations..
and all fly well..

Josh and josh above were going on how the Nutballs don't like the wind, but in my opinion there are only a few lightweight models that do... for windy conditions models get better as they get bigger and heavier.. the Nutball is no exception

There are limits to going too big, as they get more and more docile.. 26-32 is about as big as I would recommend

J and J are wrong about flying in the wind. You can make just about anything fly in the wind, it's all about ballast, trim and use of the throttle.

My sloping cardboard NutBall proved that.

Oh well, they're young and don't know 'everything' yet.

Here is my nutball. Electronics not installed yet. I`ll install the electronics posted before, but it looks like its too tail heavy. It was made from a foam board like elmers (here in Portugal is called k-line) with the paper pealed off in one side for the body, but the rudder has paper on both sides.
Does the rudder looks too big? I dont have the electronics right here, but i did some experiments with similar weights and it doesnt balance at 25%. Any ideas?

Ramen - looking good so far I was working on my nutbball this weekend and have it done except for the LG. Mine doesn't balance out to 25% either but it is somewhere in 33% range. I had about the same balance on my BluDart that I built not too long ago it flies wonderful so I am not that concerned. I will post some info on mine soon.

well 33% might be ok but it's a whole different animal than at 25, dont blame the airframe if u dont like it!!!
