interesting but I'd bet it's awkward as hell to get the wires from the tubes in the center to double back under the board and then double back again to get soldered to the pads. it would've been nice if they reversed everything and had the motor pads around the inside with a big hole in the middle for the wires to pop up through. i suppose you could crisscross the wires under the board so the #1 motor pads are on the opposite side of the board from the #1 arm but the wires will have to be longer to accommodate this. it might have to be mounted up a bit higher to give the wires room to run around under there too.

It look nice to me but what BL's are those?

Cant see the issue of wiring it it would look very neat with minimal excess wiring with just battery power in the middle so motor wires are as far away as possible from the FC.Nav stack

They are MK bls. Pretty pricey. You get rtf okto board for around 600 euro. Would like to know what's additionally on the dist ring/board that tries to justify the price and who makes them.

 

[Bartman]

they may be equivalent to MK BL's but I don't see actual MK BL's on that board. It looks like someone may have taken an MK BL and rearranged the components to fit the board layout.
600 euro is about what we pay in the US for a fully assembled Okto power board.

If you look again you will see that the SkyJib 8 is included in recommended applications for this power distribution board. A recent email from myself to Droidworx to try and get some definitive information on SkyJib specs, availability and power requirements elicited a response from Linda that mentioned the Swiss Aerodrone guys as having produced a suitable power distribution board. It is currently the only commercially available item that works. MikroKopter is still working on it but has not yet announced a solution.

Since I am here I will ask the question that I was going to ask before I opened this thread.

I just received an AD-8 HLE, having decided to wait a bit before going the whole hog with a SkyJib (mainly because it is just so BIG and won't even fit into my truck unless all the other heli's are removed - plus it ain't quite available yet). First impression, having loosely tacked it together to ascertain where extra holes have to be made, is that it is indeed a really well designed chassis. I love that the arms can even be swung in for easier transport if necessary.

I ordered it from AltiGator yesterday afternoon and it arrived this morning at 8:00.

Kudos to AltiGator !

Unfortunately, they did not have a sufficient number of motors in stock at the time I filled the shopping basket and so they were ordered from a French place (FlashRC). The AltiGator gent phoned after I had clicked 'BUY' to ask me if I had forgotten to order motors because they had just arrived. Dammit.

Anyway - and finally, here is the question - if the MK motor wire colours are blue, grey and black, how do the AXI yellow, red and black relate?

Just to add some glitter to this post, I just did a job shooting aerials for the local Radisson hotel, which sits smack in the middle of the Disneyland Paris golf course, and I used the MK Octo for a pre-shoot to determine angles. The actual job was done with a 5D on the big Copterworks heli but here are a couple of the shots from the Octo using a Pentax Optio S-12.

MBF
regarding the motor wires, put one color in the middle and alternate the other two back and forth with each motor as you go. only two wires have to be swapped to change motor direction. Wire one up and use MKTool to see which way it's going. If it's good, then get to work doing the rest. If it's backwards, swap the two around and then get to work doing the rest.
Make sense?
Nice pics.

Anyway - and finally, here is the question - if the MK motor wire colours are blue, grey and black, how do the AXI yellow, red and black relate?

The left side of the equation is MK3638 coloring, right side is AXI coloring.

Black = Black
Gray = Yellow
Blue = Red


So, here is the wiring for AXi motors:
A = Yellow, B = Red, C = black (CW motor rotation)
A = Red, B = Yellow, C = black (CCW motor rotation).

Actually with the BL 2.0 it doesn't matter, you can change direction in the BL software. You could wire them all the same way and then just go into MKtool and reverse as needed.

Much obliged, gents. I just wanted to shortcut the 'trial & error' when the motors arrive.
