F.A.Q. a foldable H-copter

[quaddemon]

Hi guys,
just want to share my interpretation of an H-copter: the Fold-A-Copter
In my scarce spare time I like to fly, but also to ride my bike... so the need of a transportable quad that could haul a Gopro or a small compact camera when you go riding, trekking, travelling and so on :tennis:
The prototype works so well with a Naza FC that a new version for a customer is already on the CNC table!

Ok, new FR4 version, bolted frame against glued, easier to assemble and repair :friendly_wink:

Looking good and tidy!

Really liking this idea. Nice work.

Thank you guys, I'm glad you appreciate it. There are some nice folding quad around, but what I'm mostly proud of is the arm friction blocking idea: no screws to be lost in the grass or screwdriver forgiven at home, just open the arms and fly! The system has been tested at the bench with a 3kg weight

and at the field, with a less than perfect landing due to a low battery, the arm that hit the ground simply folded slightly with no damage to the frame, I just straighten it up and in a moment was in the air again... with a new battery of course! :tennis:

whats the pricing for the frame? also how does the naza work in the h config?

Isn't the H layout just an X. As long as you get your CG correct it should be good to go.

That's right: the Naza don't know what's between the arms (x, H or Z!) and the motor mapping is as for an X quad.
In this configuration you have the camera in the front and the battery in the rear, this is well handled by the Naza even if the CG isn't exactly in the middle of the frame.

@ mailman35 : going to post you a quote, as soon as I recover the info about shipping to the States

I really like the foldable design here. One thing though about the control board mounting... it would be nice to have mounting holes in the middle area for boards like the MultiWii, KK2 etc. Maybe a set 50mm apart. I could see using this design with something other than my taped down NAZA just for a smaller more portable quad.

No problem at all! Just two minutes at the Cad... Another option, that I tested in my other projects, would be to provide in the package four expanded PVC m3 threaded eyelets to be glued in whichever location you prefer.
Cianoed in place I can assure you they will not fail... no matters how hard you land :friendly_wink:

 

[quaddemon]

Same concept in the just finished F.A.Q. I'm about to ship.
In this case a fiberglass eyelet is glued in place at camera plate location and M3 threaded

Here is the v.2 ready to be shipped to a customer in England...
You can see the dampened mounting plate that I tested with my Gopro mount and a Canon S95, 150 to 250gr. payload

Ok, the first one is out!:tennis:
Here is the parcel ready to be shipped... the whole package is compact too!:friendly_wink:

 

[Pelted]

Any flight video from this yet?

Here it is, just a fun flight with some friends at a dry lake used by ultralight and rc planes...

 

[Pelted]

Now that you've got one of these out, and plans to make and sell a few more frames?

Hi Pelted, yes, I've already contacted the CNC guy and provided materials for some more cuts both in fiberglass and lexan.
If you're interested, please PM me

I'm The Guy in England, I will be posting on here how it all goes together in the next couple of days :nevreness:

Hi
finally the v.2 version is on the assembling line: lighter and slightly larger plates ready to mount the arms.
The plates assembled as you can see in the picture tipp the scale at 195 grams... hope to keep the bare frame below 350 grams :untroubled:

A little update: a detail of the folding arm.
I've corrected some measurement to allow a perfect movement of the motor wires when the arm is retracted.
Now they hide nicely between the plates with no tendency to be tangled or kinked
