Yea... Kind of figured as much...

Thanks for your time and effort on these questions... People like you spending your free time helping us n00bs is what opens this hobby to so many.

But these have been my biggest questions

Which Motors?
Which Props?
Which ESCs?
Which Batteries?

The frame seems to be kind of a Non-issue... It seems to be limited only by your imagination and wallet.

If you're a total noob, then have a look at my beginner copter article on my blog where I recommend a few motors, props, ESCs and batteries.

I don't see any mention of the flight controller, but obviously you will need one of those. This is a really good one for beginners: http://www.hobbyking.com/hobbyking/s...723&aff=114030

The Turnigy 3s 2200mAh lipo should be great for your setup and give you plenty of flight time, buy lots of these: http://www.hobbyking.com/hobbyking/s...636&aff=114030

The RCTimer ESCs that come pre-flashed with the SimonK firmware are great, you'll need 3 of these: http://www.rctimer.com/index.php?gOo...9&productname=
You will also need some sort of power distribution board and a few other bits and pieces like a servo to control the tail motor.

Check out my beginner article on my blog or get back to me here if you have more questions.

As subara already said, you need a module and no, the transmitter doesn't come with servos.

If you buy it without a module, then I highly recommend purchasing the FrSky module and matching FrSky receiver.

That's great! Thanks a lot for your answers! I'll then wait for my kit... and see what I can do. I suspected about the gimbal stabilization not performed by the HK v3.0, but it's fine... I can do something later about that, priority is still the quad flying good first.

Just a quick update on what's going on with my blog: http://drone-pilot.blogspot.fr/

I think I might have bitten off more than I can chew trying to do an article about the regulations regarding multicopters and UAVs around the world. It seems that there is new legislation coming in all the time, so by the time I finish it, it might not be true anymore. Hoping to at least get something finished this weekend.

The weather here in the French Alps has turned bad, so I'm going to have difficulty getting out to do some of the flying videos that I had planned. I went out yesterday to do a video on the spidercopter, but I had an issue with one of the motor mounts coming loose, so that video will have to go in my out takes and bloopers video.

On more positive news, it looks like I will be starting a new contract next week, so should have more funds to put towards some new projects. I'm going to order up all the bits that I recommended for the beginner and mid-range quads and do a step by step build guide for them. and am thinking up competition ideas for giving them away.

The bad weather means that I should have enough time to finish my All-in-One FPV ground station, finish off my Halloween copter and start writing my article about cameras for AP/AV use. I've also got a Top Secret project that I'm working on that I don't think I've seen done with a multicopter before and should make for an epic video.

So, lots of stuff in the pipeline and I just need to beat this cold that I've been suffering from for the past 2 weeks and I'll be back to it and churning out more articles.

congratz on 2400 posts:P

I have a few questions:

Will it give me trouble having the motors raised from the frame like on this frame?
http://tosed.dk/billeder/flying_stuff/hex.jpg

Why can i purchase a KK2.0 flight controller board for 30$ when a NAZA will set me back almost 20 times that? What is the difference? (quality ofc, but why the HUGE gap?)

What is the diference between the x and + settings on a quad and hex copter? Is is just that the props sits in a x instead of a +? This would make sense, but i want to be sure:P

Thanks for your time!

Random FPV question.

Are most or all FPV cams an additional small camera attached to an MR...or do people use their GoPros and other cameras to simultaneously record video AND transmit fpv video to goggles/screen?

I notice some FPV setups use different frequencies. If I have a 2.4 ghz tx, I need to get an FPV setup with a different frequency, right?

Can you explain a little more about this and other FPV basics? Thanks.

Might have better luck reading the first few posts from the thread below and then asking there.

Having the props raised like that won't cause any problems, there's already quite a few frames with a design like that.

The NAZA is more expensive because it offers more features. You can upgrade it to have GPS, which will allow it to hold position or even return to home if you have a failsafe.

The difference between x and + is just to do with which direction is forward. This picture should make it more clear:

You can use the GoPro as your primary FPV camera, but for a few reasons people tend to use a separate CCTV style camera for FPV. The reason for that is that there is a very slight lag in the output from the gopro and most goggles and screens have 4:3 aspect ration, so you get black bars top and bottom in your goggles/screen. The other benefit of the CCTV style cameras is that they tend to have better light handling ability (if you get the right one) and you can choose a lens with a more narrow field of view which makes it much easier to fly in close proximity to objects.

If you're using 2.4GHz for control, then you can't use 2.4GHz for video. That means that you will have to use 900,1.3 or 5.8. A lot of people are using 5.8GHz on multicopters because the antennas are nice and small and it works well with 2.4GHz control.

The major downside to 5.8GHz video is that you really need to maintain direct line of sight or you start to get video drop-outs, even at quite short distances.

1.3GHz is pretty good for penetration, so great if you occasionally go behind a tree or other objects, but the antennas are a bit bigger and more difficult to put on a copter (if you're using a skew-planar antenna like most people these days). The other problem with 1.3GHz is that the second harmonic step on top of the 2.4GHZ for control, so you have to use a low pass filter and try to get as much separation as possible between the video tx and control rx.

Of course you could fly on good old 72MHz and use 2.4GHz for video, or get yourself a long range UHF system.

Tip.. as a primary 1080p camera for a quad, I'd rather use a Drift camera, as it's cheaper, the shape is so much easier to deal than a GoPro... also includes the LCD and remote for free
