We use our ZeroTech Dobby drones for youtube and video work. We love the portability and simplicity of the craft, but sometimes we wish it had more stability.
Our solution: a 3-leaf center hub!
The Dobby's propellers don't weigh much at all and the gain is signifigant, but the tri-blade design cannot fold up completely, hence why ZeroTech made the Dobby a 2 leaf propeller.
Please read these warnings before buying:
- Please clean out the screw holes with a drill bit before trying to insert the screws. Shapeways cannot print the screw column walls thin enough, so they are a tighter fit that we would have wanted.
- Please buy a spare propeller leaf for each rotor. The Dobby typically only comes with 2 leafs per rotor, and this (by definition) adds the ability to have one more. This does not come with a propeller.
- Does not fold up completely, unfortunately. We're working on a v2 that might fold better.
- This is a prototype. It works on our craft, but results aren't certain yet.
