Hi, guys !
I want to show you my new products . That` :
CF frames for 3- and quadrocopters. Also you can built 6- and 8-copters (by co-axial sheme) with this frames.
- The measurement between copter`s center and motor`s axe 350mm, so you can use powerful motors with big rotors
- Weight of frames : ~275gr for 3-copter and ~340gr for quadrocoper

3-copter`s frame

]- quad`s frame .

You can to install this frames on special CF landing gears, which will provide nice and stable take off and landing :
]

- the clearance of gears is 205mm, widht between skids - 450mm,
weight ~270gr.
Landing gears are equipped with camera mount`s holders with vibroabsorbers
] .

Camera Mount is compatible with pocket-size cameras, like Canon-Ixus, SONY or other and also GoPro cameras
tp://]and is equipped with two digital high speed TGY930 servos on aileron and elevator drives. Each axe are hanged on double ball bearings in aluminium cases - elevator axe has 2 x 2pcs of BB with direct drive from servo
] and aileron axe has 2pcs of BB with "push-pull" drive ]
Assembled camera mount`s weight ~250gr (with servos).
]

]
]

Working angles of camera mount : +/-30 degrees on aileron and +20 -90degrees on elevator.

Nice. I think the camera mount would work good for a 500 class heli also.

Where did you find the vibrasorbers? All I find are too large, 1/4x 20 and bigger

Yes, sure - this cam.mount can work with any heli, which will be able to lift it into the air. I`m need only to design adaptors for other helis.
This vibroabsorbers you`ll find inside any broken CD-ROM from personal computer

The quad looks great.
Is the QuadPowered Base a good choice?

I have already finished drawings for 6-copter - it will be shown within ~1week, but I think, what quad`s sheme is enought optimal to choise it from other policopters shemes - you`re need a little bit less electronic devices, than for 6- or 8-copter, and it`s more easy to ajust, than 3-,6- or 8-copter. And at the same time - you have enought space to install big rotors, so you can use powerfull motors and your "bird" will be able to lift not only pocket-size cameras.
I`m working now to built landing gears with clearance 230-250mm and camera mount for full-size cameras like Canon5markII - I`m sure, what my quad will be able to work with it.

Today I have made some modification for flyght control unit mount - now it`s equipped with vibroabsorbers, and now it`s possible to fit any F.C.unit - with diagonal or stright direction.

Nice parts! What type of cutter do you use to cut the carbon?

Those really nice frames, and the price is good as well.

A few questions, why do you put the mount for the FC so high? Can you make it flush with the frame? Do you have something to protect the FC? Do you use the space under the FC mount for lipo? Thanks.

about space between cam.mount and copter`s bottom
- the space between cam. mount holders and frame`s bottom can be used to place additional lipo or some other equipment. If it will be not necessery - it`s possible to put cam.mount more closely to frame.
protection of camera and copter
- at first - those landing gears are really strong and springy to absord a main part of impact`s energy in case of hard landing.
And also in cam. mount I have a few not-strong (breakeable) parts - that`s link rods on roll axe`s "push-pull" and plastic parts between tilt servo and cam.swing plate. I think, what in cases of hard landings all those elements - landing gears + breakeable plastic parts can provide enought serious protection for camera and copter. But ,syre, I can`t guarantee protection in case of crash. Sorry, guys - crash is crash, and in this case all will be in Fortune hands.

Any particular reason why you are using two types of screws? Hex and Phillips?

you're see the photos of prototypes -I assembled its with bolts, what I was have a few days ago. At last Friday I've got ordered earlyer black hex-bolts and now all my products are assembled with one type of bolts- black/hexagonal.

Just an observation:

The attachment screws at a 90 deg joint appear to me to be very weak construction and susceptible to unrepairable damage. I can see that your forte is carbon fiber but a metal clip or bracket would be a stronger joint and could be replaced if damaged without loosing the main carbon plates.

FWIW

If I wanted to build my own quad (I'm sort of a hacker/home machinist) would your control (mixer) be available to sell seperatly ?

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Yes, sure - I`ve thinking about this problem , and at present time I`m preparing a set of aluminium spacers and brackets for my polycopters. It will be good way to reinforce frame with small additional weight and to make it more comfortable in repair .

It will be possible, but a little bit later - at first I want to test some systems and to decide - which will be choised.

If you don't mind another suggestion ...
I believe you could eliminate the top and bottom carbon plates on each arm if you bent sheet metal clips into a "C" shape channel and used "Pem" nut fasteners mounted in the metal brackets. Each of these C clip channels would be identical using multiple clips instead of the top and bottom plates. Of course you would use a mounting hole in the side plates instead of the fancy slots. The cost of manufacture would go way down and comparing apples to apples for strength it may even decrease the weight of the whole craft.

You do not need a lot of torsional strength in these arms or you would not be able to get away with what you are doing. However you could use some durability in the fastening area from what I can see.

Really - I see, what arms of my frame are much more torsional strong,than it`s neceesry but I`m not sure, what will be possible to exclude top and bottom plates, because withoun its arm will become very flexible. But I can to check it - why not?
Anyway - THANKS A LOT , guys, for all your questions and advices !!! And, please, give it more, because live discussion that`s best way to find optimal frame`s design , and as result - optimal polycopter!!!
