Hello, Kelly!
The proppeler is one quarter from the center of the sphere.
The battery is in the base of the sphere.
The diameter is around 330mm.

Good morning Paco,



Thank you for the information on your sphere and great video, that is very helpful. I need one more specific piece of information that will be very helpful. Please reference the attached photograph of a crude drawing I made.

What I'm looking for is the center of gravity of the craft while suspended from a string in the area of the Meridian or center section of the sphere. If you can take your sphere turn it 90° and suspended it with a string at the center gravity and then measure the distance from the suspension point where the string attaches to the sphere to the center of the Meridian; this will yield the center of gravity of the craft in a horizontal position. If you can post this measurement in millimeters it will be very helpful for everyone interested in sphere development.

Thank you

Kelly

Paco,

Attached is a simple diagram for a possible test stand for your sphere. If you suspend your sphere from four chairs with light string just long enough to suspend it a few inches off the floor it will allow you to ascertain the basic flight characteristics without the possibility of damage. It might be a good idea to put a soft blanket directly under the sphere in case one of the strings breaks

Hay thanks for the link, and also the comment.

No i didn't
But i have talk with Alex direcly when i was doing this and he was supposed to do a configuration for our ball..

But since Jonny have no money right now we put that on ice for now.

Still want that to be in the air..

Some changes to the sphere are already needed, it was said by others on the begining of the forum but since it was already cut we tested it like that.
