The Misfortune
Thursday March 10th 2016, sad, stressful, and rainy day in New England. I ran the misfortune of having MassGov deny my appeal for my only speeding ticket, and my only infraction with the law to date. Meaning now I owe them some money, and my insurance rates are sure to spike on my vehicle. As well as all my dreams of walking up to Washington DC, with a squeaky clean record, to score myself a security clearance which will allow me to consult for DARPA the DOJ and the DOD in my mid to late 30’s, flies right out the window. Well, I only hope they can forgive me, and turn a blind eye to it.

Turning Things Around
That being said, I look to turn my misfortune around by releasing a concept of mine to the open source community. This concept was designed by myself with much needed input from Andrew Merlino from the 3d Heli community. We have spent approximately ten months developing the system on our spare time.

The Problem And The Solution
In MultiRotor FPV to get really good, you have to crash, and crash A LOT. Which can be demoralizing to some, specifically to those of us who do not have personal mechanics. So I started thinking. I analyzed F1 racing, its amazing that the world record pit stop is said to be 1.923 Seconds. Why can’t FPV crashes or mechanical malfunctions take equality as long? So then I started looking into mil-spec devices, specifically the M4 or “AR-15”. Two Pins hold the main assembly together, very interesting. And its amazingly helpful for the men and women deployed over seas, they don't not have to be rummaging for sub tools to clean the “tool of the trade”. Now my mind is really thinking. Six revisions later, and over 500 test flights. I present the Ozone Drones 300 sized X-8 Pro and Quad-X Racer field strippable modular frame design.

Important Specs and info
I printed the frame out of PLA, two walls thick, with a 30% infill on my MakerGear M2. And as you can see in the video it flies very solid for using little to no hardware. Altho the spacers seem to be useless in the Quad-X frame, they play a crucial roll in the X-8 frame. Spacers on the X-8 frame should be crazy glued back to back, to help score some rigidity. Keep In mind for the X-8 you may need at least 60C discharge rate packs. To avoid cell damage and puffing. Eight motors pulling peaks of 15-18 amps at 12 volts, (3s) boils down to 1500-1700watt peaks. Amps sure do add up. Now you have a 300 size that peaks out at 1.7kw.   
 
Motors Used: Emax 2300kv
Props: 5x6 carbon fiber
ESC: Emax 12amp
Pack: 3s 1400mah or 2200mah
Controller: CC3D, NAZE32, or APM
Frame Weight:185 grams
X-8 Frame Weight: 270 grams
Quad-X Weight With 1400mah pack: ~1.5lbs
X-8 Weight with 2200mah pack: ~2.25lbs
Need a bag of: Hitch Pin Clips 3/16 1”


Cons (Need to be Solved)
-Mild Boom wobble
-Not made of Carbon Fiber
-A little Heavy(slowly getting stronger and lighter though)
-Currently can’t be purchased
-Requires further development
-Development account unfortunately seized by Mass.Gov   

Pros
-Less then five minute frame assembly (F1 Inspired)
-Easy to repair
-No tools required for air frame assembly (AR-15 Inspired)
-Use of Hitch Pin Clips is the only hardware required for frame assembly
-Modular Design (Lego Inspired)
-Designed with Lean Manufacturing methods in mind     


If any one has any ideas on how I can improve the frame, please let me know. I need a solution to solve the mild boom wobble which gets progressively worse as you fly it, specially after mild crashes. Having more eyes on the subject may help accelerate development. The X-8 still has to be test flown, and due to my misfortune, I will be forced to pause development of this system till I accumulate some funding. I will be patiently awaiting constructive criticism.

Moral of the story
I couldn't think of a better way to vent out my stress, and I hope you enjoy whats come of it. Remember don’t speed, and don't drive overly tired. (that's is what FPV is for, right?)  The Police are only doing their job, and the fact that you eye’s can not register stimulated wavelengths of near infrared light, is no excuse. Which sort of gives me an idea for Augmented Reality HMD’s…hmmmmmm.

Edit:

Robert Below mentioned Hot Glue. Works great to lock in the booms!
