Hi !
What about 2 servos 90 deg. heli swash plate mix,
with simply swash plate it can move as many vanes you can fit with only two servos.
Also little mod. heli swash plate can be use.
Only my 2 cents

and if you use 3 servos with the right helicopter mix you can use the same vanes to control yaw as well, but you must set up the swash plate to slide too

I am a bit late to the thread but what the heck. This is the rough model.

Gary Mortimer · Jul 31, 2011, 05:33 PM

Looks good, I'm waiting to see everyone elses first attempts before modifying mine again.

Aside from the horizontal rings, it is finished. I am not building it though. Maybe in a month or two, but not any time soon. It has eight rings. My ball has a 14" diameter and will accomodate a prop up to about 10". You simply remove what you need to remove from the center column. The center rings are 6mm. Everything else is 3mm.

The official version is complete. I just have to put it together to make sure everything fits. Would anyone be interested?

boredom.is.me · Jul 31, 2011, 06:55 PM

Done... Would I recommend this for the average builder... No!

Hi !
I do not see any problem to build the ball.
But control mechanics and software - maybe ordinary gyros only ?

My ball will need one 24"x36" sheet and one 12"x36" sheet. It is a lot to cut out by hand.

I do not see the controls be difficult at all. You will not even need a gyro. The battery needs to be located as far down as possible. The battery would act as a natural stabilizer.

My design has a cage to the bottom. Meanwhile, the rest of the electronics could be mounted between the battery and the motor. The servos should be mounted right under the motor mount.

How would the battery act as a natural stabilizer?

Weight. Think of a balloon.

The battery on the Japanese one seems to be on the CG and that allows it to roll nicely when on the ground!

boredom.is.me · Aug 01, 2011, 01:22 AM

They have a relatively unlimited budget. They can afford to put three gyros, plus a back up gyro for each gyro.

That doesn't work: no matter the orientation, a balloon lifts upwards while the drone lifts in the direction of the vertical axis.

This has been discussed over and over again.

I think you are still missing my ENTIRE point. When I referred to the balloon, the discussion was not abou orientation of lift. The lift was balance. It does not matter how strong the wind or lift is, the heaviest part (the elongated end or the filler part) will always try to sink in relation to the rest of the balloon.
