Travel Quad

My humble "Travel Quad":

The idea is to have a small system that will fit in airline carry on.

1200Kv Turnigy Motors
15 Amp Turnigy ESC
8 X 4.5 Props
2200 mAH 3s LiPo
Hobby King KK2 Board
Hextronic 3 AMP BEC
2.4 GHz VTx
CX-161 FPV Camera
DragonLink
Stock wood from Coop Byg
Foam Landing Gear
808 #11 Key Chain HD Cam

It shares the same ground station and batteries with my EZ*.
I'm getting about 8 minutes of flight time per pack.







First FPV flight:

Foam landing gear = brilliant

I have not seen that before, and it's a great idea. Cheap, easy to fix, etc.

Have you done any calculations to choose the foam density/properties? Too soft = not enough buffer; too hard = does not compress at all, therefore no buffer. Why the curved shape on the bottom?

I appreciate the way you use ordinary materials e.g. wood beams.

When you have time, it would be nice to know the all-up weight, thrust, etc. What is the Dragon LInk used for?

Hi Roger,
Thanks!
No calculations. Mostly trial and error.
The curved shape in theory pushes back more the more it is compressed.

All up weight is about 16 oz without the battery.

I've been hanging around the heli line recently. Swing by if you see me.

Awesome project, if you are flying the keycam, might as well use it for FPV video also.? I find the KeyCam beat most FPV cams in terms of clean image quality. and for quads I like flying with the D version with the wider lens to get a better feeling for drifting.

First Trip

I took the little quad on its first trip.

Lancaster Soccer Center (4 min 21 sec)


More Airwork with the Travel Quad (3 min 28 sec)


I really like the portability and subtlety of this little aircraft.

WOW, I love it, could you give the width & a close up of the way the sticks are held together? Also a dide view to see how it's stacked in the center.

Can I get a separate power board to keeep things clean?

The two cross members are literally stacked at the center and attached with giant staples and gorilla glue. I added some length of the same stock to strengthen the structure as well as provide a level plane for

The frame is is 11 X 11 inches...16 inches across.

Cool build! I did something very similar. I used two sticks of the same length then routed the edges so they were rounded instead of sharp. Also using the router I cut a notch in the center of each stick exactly halfway through. I made sure the notches were a hair smaller than the width of the board so I had to pound them together with a hammer. Even with that tight fit, I decided to use a wood plate on top with 3mm screws going through each arm to help hold it together.

This thing is incredibly strong and with 1400kv SunnySky's and 8" Carbon Fiber props, its extremely fast and agile. Now I just need to practice flying like Warthox.



Here's another pic with lights added.

multirotors v ez*

Hi scrtsqrl's

I see that you have also been bitten with the multicopter bug.
I first tried a factory made tri (scorpion) just to see what it was all about but realized that it easier and cheaper to build my own plus I enjoy the making of them.
I now have built 6 tricopters (950mm) and 1 quad (40mm, from m-m) 3 of my older big tris I've scrapped and now have just the scorpion and 3 aluminum arm 950 tris plus the first self build quad

I still occasionally fly one of my ez* but they are weather dependent whereas multis can be flown in all sorts of wind conditions.

the quad/scorpion/and one of the big tris have a key cam fitted the other 2 big tris I've fitted with the Horyzon camera.

good to see that your still about.

Hei Ray!

Additionally, Quads tend to travel better.
I'm glad to see you're around as well...
