What makes the difference, is that the side area gives the rudder something to work against and makes it more responsive. If you find it's 'a little over the top', give the control surfaces less movement and make sure the CG is not too far back.

At our last indoor I was demonstrating just how stable the NutBall is after hearing someone comment that the NB doesn't glide. That comment from non flying, non building, non informed expert, who doesn't get it in the first place, but thinks he does. I moved the battery forward to about 25% CG and proceed to chuck it around in the gymn in free flight mode to nice gentle landings every time.

I made a 20" nutball can I use a TP 2410-08, 2 9gram servos and a 2s battery that weighs 3.130oz Tired of waiting for my parts. Is this to heavy? or should I just wait?

Battery and the motors are too heavy IMO for a 20"WS NB...24g motor and 1.5oz battery are more appropriate....BTW Frank the 18" I built my FB, glides very nicely thank you

No problems gliding my Nutball either. Kinda need to glide when you're 200' in the air and you run out of juice!

The Nutball was my first ever scratch built rc plane, only Air Hogs and Stormlauncher up till then. (differential thrust)

The Nutball is what got me hooked. After flying Goldguys @ indoor one night I started building, I don't think I've stopped since.

GoldGuy's Nutball (1 min 59 sec)


Thank you Goldguy and Jonesymj for the inspiration, and by the way we missed you on Saturday @ the new spot, it's just not the same without the Nutball with his Nutball! LOL

Weigh the works. Now, if you have around 8 ounces, that will give you a wing loading of 3.67 ounces per square foot, acceptable, but not great. Doesn't sound like much, but closer to 3 is best.

If you can't wait, give it a try and then when you get your lighter stuff installed, you'll really appreciate lightness after experiencing the difference.

Just wanted to say THANKS! for the great design. I just finished up a 20" out of dollar tree foam board, with hxt500 servos, 24g blue wonder motor, ar6100 receiver, and 2s-460 battery. AUW is 5 3/8 oz

I can't believe how long it flys on the 2s, and when I stick the 3s-610's in it, it's a real hoot. I've never had so much fun with $1.00 worth of foam.

Thanks again,

Jeff

That's the first time I watched it with sound. Is that how we really sound?

Much more entertaining with the "technical" language thrown in


I had another fly of the nutball..32" Kite version (see post 2294)... its all trimmed for a nice flat glide hands off.. but power up and it wanted to climb like mad and turn to the left..so I packed the mount to give more down and right but I couldnt get enough in.. There was an improvement but it needs the same or more again... so I am going to have to make some major adjustments to the thrust lines by removing and retying the motor mount tube..
Rest of flying great, this one rolls fast and loops tight.... all fine there.... but with a forward COG it wont spin, just a flat small circlular flight path....I do like the nutballs...
Once the thrust lines are sorted I will be trying it out at night with the lights going...
But for now its pouring down and windy...at least down in this part of the UK we have been spared the snow

Dave, we mentioned you really quick on ATTF this week (episode 81) for the ultra cool kite version of the nutball. I put it in the show notes links as well, and the RC kites in the night flying section. The nutball is great fun and I really like your design. Want to see it all lit up in the sky!!

Not to mess with near perfection, but...

I just built a 20" EPS Nutball yesterday...BW,9G servos,6100E, 3s460mah...176g AUW=2.8oz/sqft...flew it today for about 1 hour on several packs, including an 800mah (204g,3.3oz/sqft)....actually liked the heavier loading, especially when pouring on the juice....I really love this thing!! its almost impossible to fall out of a hover and not flip upright instantly! thanks!


I am going to build it in EPP next (I proto any new bird in EPS first, then if its a keeper...and Nutball is definitely a keeper! then commit to EPP)

but as I was hovering about a foot off the ground, trying to get spontaneous, axial,torque rolls to occur (they will if perfectly vertical) the nasty thought of evelons to ease this move came to mind....
I don't think another 10g will hurt this puppy at all by adding the third servo and splitting the elevator into evelons, but has anyone tried this and do you get any better rolls?
