I flashed my CC3D with Librepilot - it's a fork of Openpilot by some of the original developers and will have continuing support of the CC3D FC as well as the revolution FC.

I have frame #2 in your list. I love it! See my earlier comments in this thread for details.
The onboard BEC is 5V only. You have to question whether you are going to go 4S anyway. I have run 4S on this quad. It works fine, because my camera and VTX can handle up to 24V so no problem here.
I just bought a second one of these frames actually.

I just cut my motor wires to the right length and solder straight to the esc. If you have plugs you run the risk of a plug pulling out and we all know that multirotors don't auto rotate to well............. well not at all actually.

Yep, I agree, give me solder any time. You can always cut the motor and ESC leads short before soldering. I usually solder the motor directly to the ESC when I can. If not, I cut the ESC wires really short and solder those to the motors.
On a quad I would never use bullet connectors. Too much vibration and another thing to fail.

I only shorten the motor wires if they're far too long.
Flux works well if you do have to cut them back a bit. I'd rather have wires that don't hang off the frame so they can't get damaged.
I always try to solder the motor wires directly to the ESC and bypass the ESC to motor wires. Usually that doesn't require shortening of the motor wires. But if it does, flux and a good soldering iron plus some sandpaper does the job.

Well, it swings and roundabouts though. Sometimes we get some great HK sales here in Oz, and considering how small our market is in comparison to HK's overall revenue, one can't get too upset about it. Wait long enough and they will be on special sooner or later.

I've got that quad - bought it for my 10 year old son for Christmas. It's a great quad. Flies well. Has a 600mw VTX out of the box. Has a full CC3D FC. You can do flips with it.
It's quite durable too. The arms are plastic and easy to replace, which is good because he was doing a flip yesterday from about 50 feet and smashed it into the ground at a pretty hefty pace. Only casualty was one of the arms, and a replacement is about $2 or $3.
Comes with 2204 Emax motors and 12A SimonK ESC's so it will handle 4S as well. Oh, and it has a basic OSD built in too.
I have several quads that I built but I don't regret buying that quad for him. It's quick, reliable, well made and for the price it's a winner. Obviously not as good as a custom built highly spec'd machine but for the price it's a good one.

Yes, yes and yes Bob!
It was going very fast, straight down into the ground as he was attempting a flip at the time without first adjusting the PIDs to provide quicker roll. Ie. he attempted the flip from too low an altitude. But that's 10 year olds for you...
So yes, it is a good machine for the price and the OSD is good. Yes, the machine was moving quite quickly, and yes, the arms are quite solid. Yes, it uses CC3D and the OSD is basic but good. It has sold out several times so there's plenty of spares available. Arms are about $2 each or something. The same arms are used by other quads too. To give you an idea of how popular it was - I ordered mine in October last year - this is version 3 of this model. There were almost 3 thousand of them on back order when I placed my order! And there's been several production runs since.
I suspect it filled a hole in the market which the manufacturer was initially unprepared for. Every couple of weeks it goes on sale as they take pre-orders, it even went down to about AUD$150 at one point... then back up again as they got more stock.

I'll bring it next time I come to the field.

If you like tinkering and soldering, build your own. If you want to just get up there and fly, it's a good option. Check the rcgroups thread - it's a huge thread and has many contributors. I really like it, as does Kyle...
