I decided recently after getting a chance to operate an Aeryon Scout that I would like to have a Quad UAS of my own. I have started my build of an H-Quad. The same design that was posted recently from  FliteTest.com. It looked to be an easy frame to build and is essentially a X-formation Quad. Here are the preliminary photos and a list of parts. Since this is my first Quad build I would love to get as much input as possible. Thanks

Frame: Scratch Built H-Quad Frame

Motors: Turnigy D2836/11 750KV Brushless

ESC: Hobbyking SS Series 35-40 Amp ESC w/ 3 Amp BEC

Prop: x2 CC 11x4.7 and x2 CW 11x4.7

APM: APM 2.0 running Current ArduCopter Firmware.

Here are some pictures of th
e frame.

What did you make the frame out of?  It looks like it might just be wood if it is what type/sizes since I was thinking of doing something similar myself.

It is wood.
Here is the website where I found the planes.
Very easy to build. The rest of my building parts are on the way.
The wood only cost me 5-10 dollars.

Here are some updates on the Build.

I have completed the build so far. It is ready for flight testing. I have checked the motors and all are spinning in the right direction, ESC are calibrated, verified that the right motors increase and decrease in stabilized when a force acts on the frame.

I have all the PIDs in the default settings is this adequate for a first test hover? This is my first quad so I am trying to get the most information I can get from the community.. Thanks in advance.

I was just planning a quad with same specs waiting for your test flight video 750KV vs 11x4.7 prop should perform great....

Comment by Joseph on July 18, 2012 at 7:45am

are you saying with the stock Arducopter firmware it should perform nicely with no major tweaks?

Comment by Khurram on July 20, 2012 at 7:34pm

No actually I'm more concerned with vibration less platform and more lift, 750KV and large propeller should work great (as per theory), most quads are being built using 850Kv with 10x4.5 props and we see too much vibration and not much lift power there........Therefore I planned this combination and looking forward to see your results.....Good luck

Well I had a great couple of flights today. I was able to test Alt hold at low and high alt. all went pretty good. minor drifting but winds were pretty brutal. I also tested loiter today and it did pretty good. I will have some little tweaking to do and I will also have to balance the props a bit more to get out the remaining vibration. All in all I am very impressed with the set up. I have some video but I will not have it up till later today.
