Octo Build

Frame: Have a friend coming out with a new one, very excited about that.

Motors: Scorpion Came out with some cool. Scorpion SII-3014-830KV

Speed Controller's: Not sure what to use yet.

Battery's Hyperion seam's to be the only thing that hold's up with a good price that i found.

Camera Mount: CINESTAR SLR is looking prety good $950.00, priced a little high.

Flight control: DJI $ 1,100.00
Hoverfly $900.00
Hurculie's $

Would be nice to have:
Landing gear: Something retractable would be nice.

Xbees: I have them $189.00

Motor Angle adaptors.

Props: NO IDEA

Interesting Tim
Seams like guys are using cheeper speed controler's.

I was used to Heli's and thought Kontronic or something would be needed.

Cost to buy 8 at 350.00 vers 750.00 or more??????

Will have to look into those battery's, I have not had too much luck with battery's over the years.

Thankyou for your info, hope i can return the same someday.

I'm using the GensAce 4s 5300 on a large Hexa and getting about 10 mins of flight time. I was using a SkyLipo, a GeForce, and a Turnigy Nanotech of the same size and for some reason was only getting about 5-7 mins.

As far as ESC's go, I've used expensive and I've used cheap. I have gravitated back to the Turnigy Plush series in the 30A-40A range. I know it's HK, and considered cheap or budget, but the reliability is there for me.

Motors, I suggest the Avroto for larger Hexa/Octo. The quality is really fantastic. I disassembled one of the first ones I got and it's top notch. Plus, it's made specifically for Multirotor applications. I especially liked that it comes out of the box with long leads.

I agree A+ for Avroto
That is also what i found is that lot of people are haveing good luck with Turnigy Plush series in the 30A-40A and at 12.00 or 22.00 bucks Not what i am used to.

I am now leaning to the Hurkulies board but after seen the price of Turnigy speed controls. Hmmmm 900.00 vers 200.00.

I also have two MK's in a box that a friend gave me.
They are crashed. Be a good projeck considering the MK Bl's were one of the problem's.

It will be another month for my friends frame to be out of production and on the market.

I want to build more of an industrial AP/AV model.

I tried those and with the avrotos I saw a lot of flex. Also, if you roll to one side or another they bend a lot easier than actual trex booms. So I'd suggest going with actual trex booms or the carbon that Rusty suggests on the AGL site.

Thankyou for that.
That helps because we are going for a bigger platform that will be a heavy lifter.

I had a friend go to: Alreco Aluminum Surplus
11299 Brighton Rd,Henderson,CO 80640

Lets see / They only had about 5 acre's of material.
You guessed it just about anything you want in aluminum.

He spent 100.00 on aluminum T-6 tube to build 2 Octo's plus plenty for spair's in different size's.

So i just need a center hub design.
Have you guys seen any cool Octagon shape designs around.

Seams like AXI is motor of choice.
Here is a link in another forum on this if interested.
http://www.rcgroups.com/forums/show...28#post20885537

There is only one good frame to use if you want to save $800.00 to $1,800.00. And that is the one from Rusty's frame.
Or you build your own.

The gimbal looks to be the new one coming out from DJI that is going to take a jump on the other's if it is affordable.

Still have not found a heavy amp power distribution board.

DJI Wookong M seams to be the standard.

HansAuf gave me some good info so i purchased some aluminum tube to fit the bill.

AXI Motors and props will be bought at the end when we have all up weight figured.

I have component's all cut out of balsa, so i can make up a model of all the parts and piece's.
Will probably machine one out of aluminum to acept all of them and the booms and gimbal.

This is a lot harder than what you would think.
Would be a lot easier just to go buy something.

Have not seen any aluminum welded units out there.

While people regard the WKM as "the standard", it can be a bit much in setting up for a relative noob.

I have the HoverflyPro board (US$450) on my hex diy hex and octo's. Easy to configure and they fly really well using a single gain channel on your "gear" switch using end-points.
I have flown my hex in 25mph and it is rock-solid!

The latest firmware is awesome. They have employeed more staff to improve there communication and service... and it is working!

just my 2c worth...

Here is my latest diy octo...

Nice Thanks for sharing.

Looks like it is working good for you.
Will you clean the Video camera lens and give some more video with camera on it, i would like to see what some weight does to it.

I like that landing gear.

Could you give us some close up of it and share a few details about it.

Found some new unique materials to use.
Light / Very Very strong.

I am going to be doing some work at a shop where there is injection molding and lot of CNC going on.

I was shown three different material's to use for what i want to build.

I was very excited and could not believe they were so strong and light.

I can not remember the name's of what they were callled but i am still shaking my head.

I know one of the material's used was expensive is why it is probably not seen.

You have my attention....

PLEASE....keep us posted as you move forward.

Are you going to design this setup in solidworks or the likes ?

It is always awesome to see and hear of people pushing our hobby with new ideas....

Best of luck....

PROPS, Go with XOAR's Precision Pairs. I have 12's and 13's, in Wood or Carbon


Flight Control.
Dont wast your time with Hoverfly. If your using stand alone ESC's then go with DJI. If your going with the Hercules like I use, then go with MK.


LIPO's
Just get the 4S Nano Tech's. Ive been using them over a year with out a problem.

Camera Gimbal

Go with Photohigher, But WAIT about a month till they release the upgraded, DIRECT DRIVE AV200 with Stabalization.

Or get a AV200 360, and add your own 3 AXIS stabalization Like I do.

MOTORS
If your on a budget go with AVROTO's. If you want quality Then get the AXI's

I have tried lots of configurations. My favorite, and most reliable set up thus far is the following. Just my Opinion,,,

AD8 OCTO, MK Flight Controler ETC, Dual Hercules controllers, AXI 2814/22 motors, XOAR Carbon Props, AV200 Gimbal, Dual 4S 6000 mAh lipos.

Pete, What is the advantage of the retracting landing gear ? To pan don't you just rotate the quad ?

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

The Retractable gear comes in handy for 360 mounts. The Pilot can fly the copter, while the Cam operator controls the gibal (panning 360 if needed). For that set up, you do not want landing gear hanging down.

I've ditched my retracts. As my Octo is light-weight, the extra 400g of retract wasn't worth the complexity and hassle. It has been replaced by a fixed carbon rod u/c. The Octo is primarily for stills and the mount pans 40 deg each way without haing the u/c in the shot
