+1 I was very nervous the first time I tried to build one (although it was a clone) and am now on the original FC2.1, Rusty/OMM I2C isolator, 1hoch4 ESC,s and so far so good. Once you do the first build and start understanding the system, it gets easier and your confidence grows. Plus I got tons of help from many great people here on RCG.

Checking each joint one at a time now real close up so I can make sure there's no shorting going to occur.

I don't mind a challenge but this one is trying my skills to the limit.

I use the fine tip only for very small pads/wires (I2C) and the medium tip for all other joints. Having temperature control on the Hakko unit I am using has helped me a lot, as it does compensate for my lack of skills LOL

Here are some photos that show the modified camera beside an unmodified one. They were different colors, though. The modified one was silver, originally.

While I had it apart, I added wires for focusing, tripping the shutter and power.

I'm away for a few days, but if anyone is interested in more details or photos, I will supply them when I return home.

Edit: Now that I think about it, I believe I added wires for power only. I think that focus and trip are through the expansion connector. More on that later.
Hi Don
I also use the EP1 on my Octo, thought I haven't been as drastic as you and striped it down, it fly's well in std form.
I did have a fault with it after a few weeks so just as well it was not striped as it was fixed under warranty.
I made up a modified plug to give video out and fire the shutter, just bought a remote shutter cable and pulled it apart as well as a video cable so I could re-wire the plug for both.

Hi John

How did you manage to get both video and shutter trigger to work on the EP1? I had a play with this but could not get both to work simultaneously. The shutter wiring seemed to disbale the video signal. Did this involve a resistor in the wiring? Do you have a wiring diagram?

Hi Guys,
Just a quick question. I am using a Futaba 10cg with my quad so that means I am having to use a ppm encoder board, as I don't like extra bits I was wondering if anyone is using the Mk Futaba 2.G receiver??? If so what do you think.

Futaba Receiver R6107SP - Special version

https://www.mikrocontroller.com/inde...roducts_id=477

I could go back to a JR DX9 (had one before) but I worry that only using the one satellite receiver I could easily go out of range, remember in the UK that 2.4 Ghz DSM (JR Spektrum) is one tenth of the power of the US JR radio (9503).

Your thoughts please.

Cheers

Paul

Simple answer:
http://www.hobbyking.com/hobbyking/s...dProduct=14354

Advantage: huge range, ppm out, and plugs into your futaba.
Oh, and its also cheaper than anything else you could get.
Oh lawd I just clicked on the ripoffkopter.de link. 80 eur for that?? Ha ha ha.

Thanks for that but my 10CG has the integral TX module so this will not fit.

Hello


hi I'm starting to save my Penny's and will be buying a MK soon but have some questions if that's OK to ask one I'm thinking about the Quadro XL and I'm thinking of building it my self to save some money the one thing that scares me is the programming part I'm not really good with computers but do OK how hard is the programming i have had a few quad and have also built i few should i spend the extra money and have a RTF quad built these are just a few of a lot of question info will help Tom

I was at Zoltan's last night and we were discussing Hexa Vs. Quad. He was pretty confident that the Quad is much more wind stable than the Hexa.

He also had a small 12" ish quad he was building with the 8" epp's. It looks pretty cool and would be great to fly in Sport mode.

Steve is right. Lots of flux (and flux cleaner after).

More heat is better then less heat. 90% of my soldering is with a 25 watt department store iron even with SMD.

Practice on something first on just how much heat you need. Old computer parts are great for this.

The goal is time... less time to heat up is better than more time. Get in and get out quickly.

I once used a HUGE iron to fix an ESC when I knocked off a small SMD cap. It wasn't pretty, but it did keep me flying over the weekend.

Thanks for the continued advise, I think I have rescued some of the dodgy joints etc having used a microscope to examine them it was a real eye opener seeing what I thought was minute expanded in to large scale

I'm most certainly my own worst enemy as I begin to doubt my skills despite being careful and I just have the dread of building the entire thing then nothing happens when you plug the bty in

Paul has kindly directed me toward a fella that might be able to assist but I do appreciate self assembly teaches us so much more than having it ready built.

Will keep at it but on hold at the moment as I need the replacement CTL from MK before I can do anything else.

Cheers
