T's Hobbyking Thorax Build.

[tupoar]

I couldn';t help myself... 

http://www.hobbyking.com/hobbyking/store/__66622__HobbyKing_Thorax_Mini_FPV_Hex_Multi_Rotor_Frame_Kit.html


Will be running Naze32 and 3S Batts of some sort.

Now I just need to decide on the power system

RCX 1804 2400kv + 10a SimonK (I have these already)

or

DYS 1806 2300Kv (Goldies) + 12a Emax Simon Series (need to buy 2 motors and 6 esc';s)

Any thoughts?? 

EDIT: it has come to my attention that this frame is a blatant clone of a Clayton Harp (aka gearwolf-OP on github) design posted 4 months ago. Most disappointed by this action.

THat looks interesting TP, not sure about the green tho!  Have you considered 4 cell';s for a tad more jip?

I';d vote for the DYS myself, they';re immensely powerful, very punchy, although a bit chunkier than the RCX1804 motors.

Does anyone know if the Naze32 will fly a hex with only 5 motors if one failed (ie. like Naza M and APM will)?

[nub]

aye the green is a bit hmmm, 4S deff give the RCX';s more pop ::) makes my mini H fly the way it should do, will be keeping an eye on this build though to see how it goes, good luck.

[tupoar]

Well I';ve put my RCX motors up for sale, if no one wants them I';ll use them for the time being.

NAUGHTY HOBBYKING!!

I';d just use the 1804s + 3S, a bird in the hand and all... And you';ll really appreciate the upgrade to something punchier next time the bug strikes  :)

[tupoar]

Update:

I';ve ordered a second frame! there is method behind my madness though!! I';m going to use the extra top frame so that I can create room to house the battery within the frame. The rest will be spares.

I have now disabled my PP account, cut up my credit cards, and disabled access to Hobbyking and the for sale section until further notice. 

[Hands0n]

Freud would have a field day with you

Looking forward to seeing the hex fly 

[tupoar]

Update:

Motors are now on their way. I';ll be using the DYS Goldies.  :evil

Just need to decide on esc';s... Emax 12a Aimon Series or Afro 12a v3';s.... 

[Hands0n]

Afro 12A (non Opto) are in the HK UK whorehouse ...   Opto are only in International at this time <bah!>

[tupoar]

Update:

I have the motors, esc';s and fc sorted. Just waiting on the frame. 

Found this on youtube to wet the appetite

That looks badass ::)

[nub]

looks pretty decent, needs to tie up that damn dog though.

[tupoar]

A quick check on the tracking and the frame is in the UK. Hopefully have it later this week!

So here it is, the squashed frog. It is got a seriously low profile!

Issues to note:

* There is no real support at the front. Support is provided by the cased fpv cam you fit. Not an ideal solution for me
* For the motors I';ll be using (DYS goldies) you';ll only be able to use 2 holes for mounting. Again, not ideal but manageable.

Things to do:

* Replace silver spacers between the middle and top plates with black ones. Will user longer ones to provide a little more space.
* Silver spacers will become legs.
* Add nylon washers/nuts to the legs to increase gap between middle and bottom plates for housing esc';s.
* Add some spacers at the front for extra support
* BUILD THE DAMN THING!
* Add an extra bottom plate to house the battery (this is a maybe)

What is the quality of the fibreglass material like? Hobbyking says it';s FR4 rather than G10 which we are all used to using.

[tupoar]

It';s... ok. The legs are very strong and should take a pounding, the plates seem strong where supported but have a bit of flex elsewhere.

[tupoar]

So I';ve managed to get the build started. It';s been a bit frustrating but progress has been made.

I replaced the silver spacers with black nylon ones that were longer. Not long enough once I mounted the FC in it';s case above the PDB. I';ve had to go through 4 or 5 different combinations of spacers and washers to get everything to go. I also added a washer on the arms to increase space for the esc';s. I';ve also mounted 4 of the motors. I would have mounted all 6 but due to the mounting patterns on the arms, I realised that I';ve put 2 of the arms upside down so the motor wires don';t go down the arm 

I have an idea for fpv cam add supports to the front which I';ll try once i get access to a dremel...

[Hands0n]

Luvly jubbly     Its funny [not] how none of this stuff just fits together without some fettling.  Nevertheless, the build is looking good so far.

[nub]

@ the upside arms, done that before myself.

looking good though i';m not to sure about that green.

[DebianDave]

If you need a lend of a "rotary tool" (i';m too cheap for Dremel), let me know

[tupoar]

Update:

All the motors have been mounted and I';m 4/6 of the way through soldering the motor wires directly to the esc';s. Once that task is complete, I';ll remove the live wires from the esc';s, connected the esc';s to the PDB and then heatshrink them up.

Cheers Dave but we have here one at work.

1 female M3 nylon spacer + 1 M3 nylon bolt (and a stanley knife) = 1 Male to female M3 nylon spacer with as long a bolt as you want.

Placed in the '; for future reference'; file.

[tupoar]

Update:

Soldering is/was done but a few mods mean it';s now ';almost'; done. I now need to strap down the esc';s, bec and the led strobe lighting module (yellow block)down.

Next up is adding support to the front end and creating groves to slide a board cam in.

Interesting side note is that I have been conversing with the original frame designer (Gearwolf). He says that the original should have support at the front but HK removed it...... 

Ah well....

Quick Update (sorry no pics)

Yesterday I put the middle plate on. It';s a bit snug which means that the bolts aren';t long enough to be secure for my likings. So I';m going to replace all the bolts in the arms and legs which is one of those ever so slight annoying jobs that you really can';t be bothered to do but know it';ll end in tears if you don';t.

I also created a groove for the camera to slot into. It kinda worked but I won';t know for certain if it will work till I add the top plate. Either way, it';s not the right cam for the frame but I';m too tight to buy a smaller cam! I';m seeing a small network of cable ties in the offing. I';ve also modded the frame a little so I can add 2 supports at the front.

I will take some pics later.

those DYS motors look quite chunky, are they larger than the zmr/rcx';s you use, they look more like 2204 motors.

in a word, yes!

[tupoar]

Today';s Update:

So today I replaced all the bolts with longer ones. I also decided to ditch the white strobe LED';s as the controller was taking up too much room. I added the top plate to see what everything looks like. the results are attached.

You can see where I have added the groove for the board cam. It';s secure with just a tad of wobble so a couple of tiny cable ties should sort that. You can also see how I';ve added support to the front.

I';m just waiting on some LED';s to arrive and then everything will be put together and maybe a test flight....
