RCtimer Argonaut discussion and build

Since this thing just came out and I seem to be one of the first people in the states to get one I thought it would be nice to start a thread on this little hex.

http://rctimer.com/product-1177.html

From the Rctimer webpage "We have released our premiere FPV frame, the Argonaut. The first thing that stands out and sets this frame apart from any other in its class is it true 100% real multilayer carbon construction, great features, design, durability, great looks and the motor arms are a nice beefy 5mm thick yet won’t break the bank.The Argonaut is a 370mm class Hex frame design that is optimized for FPV flight with a forward platform for HD cams & FPV gear and a rear platform for ample battery and CG adjustment. One of the key features is Integrated PCB & ESC and 5vdc 5A UBEC, There are lots of FPV Mini Hex frames on the market and each have their unique features, the Argonaut incorporates them all in a top level product that is unmatched in construction and strength."

Features:

True Multi-layer carbon construction
6 integrated ESC's running BL-Heli Firmware
5 individual 5vdc regulators for Accessories
Integrated 5vdc 5A UBEC for Flight Controller

Equipment that I plan on using at this moment:

6 RCT 1806 2300kv motors
6 mystery 20A ESC with BL heli FW integrated into the PCB
1 Full Naze32 in case I want to expand to GPS down the road
Likely a 3s 2300mah lipo but the verdict is still out on this one
RCT Carbon 5x3 props
1/3 Sony super HAD II CCD-IR block camera for FPV
Mobius for HD recording
immersion 600mw video xmitter

That's about it for equipment.

The next thing is I am not planning on building this at light speed due to family and young kids coming first but I will do my best. Feel free to chime in at any time with your build stuff if you are going faster than me.

The one thing I was worried about was how sturdy the arms and board felt and how they will hold up in the inevitable crash and I have to say that this thing is fairly beefy and I am not really worried about the arms breaking before the board does. The hex also supports the KK sized flight controllers and the naze32 and cc3d sized so no worries there.

There is also ample 5v plugs said to be rated at 5A a piece to stringing together LED's or various other 5v attachments on this thing will not be an issue. Along the lines of power there is only one extra set of solder pads that are directly on the PCB so if you are like me and your FPV camera runs at 12v keep that in mind before you forget to solder the camera power leads to the pads after everything is together.

This should make for a very clean build due to the integrated ESC's so here I go. (More pictures to follow)

Keeping my eye on this one as my first hex build. Looks well thought out. Also looks like another version will be released shortly that will allow you to use your own ESC's.

Subscribing. Does the ESCs look chunky to you? Thinking 20A is a bit overkill. Are they replaceable, can you weigh one?

Edit: By the way, are thos electrolytic caps loose? In that case I would glue them down...

From pictures (and weight) does not look like carbon.
More like CF-GF sandwitch (worst of both worlds - conductive, blocks RF and heavy at the same time).
if you got one... Can you measure resistance with multimeter between sides (top/bottom) - for carbon (even glossy) it should be near zero, for sandwitch - almost infinite. Also for arms...
But based on arms pic i'm sure now (ok, 99.99% ;-) that it's cheap material, not carbon:


Oh, and spare parts? =)
Arms have nice triangle cut - they will break at this point easily, so need spares. I do not see spares sold separately?

Yes when I get home I will throw a multi meter on it. Took the kiddos to gymnastics last night and didnt have time to post pictures.

I can say the arms on this thing are no joke. You would have to hit insanely hard to break one. These arms (appear anyways) just as strong as my blackout arms and now that I have the frame together I am fairly confident you would rip the arm off the plates before they break. I will post more pictures after I return home from work. Either way I think the frame is alot of bang for the buck. There is a few things I would change on the frame that would make it a bit better but still for a mini hex its not bad.

Hi ABLomas,

Please don't worry, the material is full carbon.

Thanks.

I think the 20a ESC is smart. Given many of these small multis (I talk from experience with a ZMR250) have great power with 1806 motors and 6x3 props (thrust of 4:1) but have insane power with 2204 motors and 6x4.5 props (thrust of almost 6:1).

If I bothered to invest in this bird, I would go one of the good 2204 2300kv motors and 6x4.5 props (needing an ESC of at least 20A). Therefore giving a rig weighing in 800-1000 with battery, FPV, GPS and HD cam a thrust ratio in the order of 4:1 or similar to what the small carbon quads get.

However, if you were to replace the ESC then some 18A KISS ESC would be sweet but really $$.

IMOH more power = more fun = more crashes

Thanks for starting this thread. I really look forward to seeing your build.

Cheers

Proof?
Also, mainplate (with PDB) in photo does not look carbon at all (bottom/middle yellow, top side black, but that's maybe "yellow carbon"); also arms are gray (but that's probably "gray carbon"), top and bottom plate middle zone is gray (again, "gray carbon"?):

The PDB will never be CF.

But from the images they have there you may have a point. The other plates look like G10 with a CF veneer. CF ones normally have many thin layers of CF to make the CF composite sheet.

Hopefully it's just the model they used for the pictures and the real one has the multiple layers like the examples in this post.

Mainplate with PDB is a PCB, so glass fiber with copper layers. For the arms or other mainplate I don't know what they are composed of.

Yep, carbon vs "carbon" ;-)



Anyway, let's wait for anyone who ordered to test with multimeter... Easy test ;-)

Hi ABlomas,

Of course, that is not the carbon, how can you put the circuit in carbon? I think Harry can reply your question, he has got the Argonaut.

Thanks.

@RCTimer - Will the ESC's be able to be user replaceable? We all know how easily we damage parts in crashes, or possibly burn up ESC's.

I would hate to have to replace a whole board because I burned up an ESC, or have to put a regular ESC on my Hex to replace a burned up one.

I am really looking forward to getting one of these frames.

Hi FLDataTeK,

Yes, it is very easy to replace it, we will list parts of Argonaut ASAP.

Thanks.
