Folding Hquad build

I flew my tricopter quite a bit this summer and decided it is time for a larger more capable machine.

The Hquad seems pretty popular lately so figured that is the way to go.

Current power system is as follows.

RCtimer 2830-14 750kv motors (might replace these with sunnysky 3508's if I need more power)
APC 12x3.8 slowfly props.
Hobbywing quattro ESC
Turnigy 3600 mAh 3s battery
KK2.0 control board

Here is the cad file showing the front/back ends with arm pivots.



I started cutting yesterday and after much finishing and counter boring I have the beginnings of a multirotor.

The frame so far weighs less than I figured (800g)


Starts to get heavy once everything is loaded on top.




Slots of the bottom are for battery straps.



Basic construction is 1/16" G10 plate flush riveted to 1/2"x1/2"x0.058" aluminum tubing. I am debating weather to have the top plate screwed on rather than riveted to avoid lots of drilling when I inevitably need to get access to the innards.

Yes, and I think it will continue

quadH is easy to build, cheap, great for video, FPV and many place onboard.

Nice one, well done.

Had to find some 3/32 rivets for the Dzus springs.





Video will be here once it is done uploading. They are a bit tough to turn one handed.

Super simple gimbal. http://www.rcgroups.com/forums/showthread.php?t=1793759

The fuel tubing provides a flexible link to the servos and damps vibrations.

Hey let me know how you get along with those rctimer motors I have the 2836's and plan on running 12x4.5 props on them.

Also where are you getting your stuff cut?

I run the 850 kv motors with apc 12x3.8s on a tricopter without overheating. I figure the 750s should work well since the quad will run at a higher average load.

I cut the parts out myself on a Phlatprinter 3. It is pretty light duty so it is not perfect for hard materials like this but it does a pretty good job for the price.

I started to assemble the folding arms and might just install fixed arms if I have to much trouble getting things as solid as I want.

Hey mate,
Awesome looking build so far. I too am building a h quad. The design is just from the flight test boys
I am really surprised that your frame weight is nearly 800g. I was worried that my frame was 460g when the flight test frame was only 280g
Have u done anymore. Would love to see how your gimbal works as this is something I was looking at doing once I have it all done.

My frame is quite heavy because it is very large. It is meant for 12" props and is 18" motor to motor. I could drastically cut down on the weight by using thinner material but I have to work with what I have.

Yeh my frame is 18 inches motor to motor each way and is designed for the 11 inch props but could handle 12.
It's no problem, just makes me feel a bit better as I built one frame with 5mm ply and frame only was 530 grams which I thought was way too heavy so I built another frame with 3mm ply and it only dropped the weight to 460grams. As I will be having fpv gear, the gopro 3 in housing, a 3s 4000 battery Im sure I'm at about 1.6 -1.8 kg. should be good as I am using the dt750's rated at 1000g of thrust on a 4s. That should still put me at about 50% throttle for hover.
Sorry to write so much. Back to your quad. I wish I could afford one of those cnc machines you have. I don't think I would ever leave my shed.

Are you carrying two batts or was this a typo?

My quad is also simular dimensions and i was planning on the dt750's as well but i can not get the quadcalc to like any of my choices.

I was planning on getting the quad to a finished state minus the motor's and battery then asking help here for the best choice once i have an exact weight and size.
So i am glad you both (Helno , Macca05) also have simular sizes with simular spec equipment.

What flight times are you both estimating?
