Hi,
first of all, I am sorry if this post isn’t in the right section.
I need some help, if possible, for a project I am doing.
basically I have a box, with 5 inch x 5 inch x 5 inch and weights 1 kg. at the center I have 2.75 inches diameter free space for a propulsion system.
Can you point me to any direction for choosing a motor + propeller or edf motor or turbine?
I just need to put the box “floating”
thanks
To confirm, you need this 5x5x5", 1Kg (2.2lb) box to float above the ground and have only a 2.75" sphere in which to place the propulsion system? If not, can you tell us a bit more about the project and application?
You might need to think “outside of the box” for this one.
thanks for the quick replay.
it’s not a 2.75" sphere. its a tube with 5" long and 2.75" diameter placed at the center of the box. imagine a hole at the center of the box.
Thanks. Can you tell us a bit more about the project and application? The more information you provide, the better we can help you.
To clarify - do you need to have this box hover above the ground and the propulsion system fully contained within this tube?
Sure.
I want to have this box indoor floating to take some pictures.
Maybe I will add some other features later.
I was thinking about using the DR Mad thrust 68mm but maybe is much.
o you need to have this box hover above the ground and the propulsion system fully contained within this tube? - YES
Hi luiznunes,
You will not be able to make the box float on it’s own.
A ducted fan will not be stable and will not be able to do a hover.
What i understand is you want the propulsion system to be hidden inside and not noticeable, right ?
If your need doesn’t exceed a few cm high than you could use a magnetic levitation device. Here are some finds online:

Yes, I want it to be hidden.
Really? No chance to do it? Not even with some lateral mini propellers to help stabilize?
I need it to be 2 to 3 meters high.
Is it so different from an helicopter or a drone?( sorry if it is a dumb question)
Is there any kind of software where we can simulate this kind of projects like solidworks?
You could make it as a UAV (Helicopter / Drone) for sure but the propellers could not be hidden inside.
Hacking a Hubsan X4 Mini QuadCopter could work if there is enough trust to carry your cube. Make it hidden in the box and have holes for the propellers trust.
Of course, something custom build could also work but it would have to be a DIY project.
Example found online… (this one don’t fly well… but…)
