I'll try to make this as simple as my FPV tutorial.

First you need to choose what you want to do with your quad
  • sport flying
  • heavy lifting(DSLR cameras etc)
  • fpv(stuff from my FPV tutorial + gopro)
  • general use

Sport flying requires a carbon fiber frame, lots of zip ties and good motors/props. Get some properly balanced carbon fiber props. When learning to fly a quad you probably don't want a sport setup because it can flip 4+ times a second without problem.

Heavy lifting needs bigger props and possibly a hex setup. lower kv motors, higher voltage(4S)

FPV means maximum flight time, maximum stability. 8" gaui props for learning with 1000-1200kv motors. later switch to carbon fiber props if you have the cash.

General use is probably what you want your first quad to be. You can carry some equipment but don't expect it to stay in the air over 7 minutes. This also keeps the cost down.

  2. Frame
  3. Motors
  4. ESCs
  5. Props


Flight controller
There are a few of them, depending on your budget
HK KK board - hobbyking has them from $12.86(buddy code) to $19.99(version 3 with bigger cpu). Get version 2.1.
Multiwii - about $100. Not for noobs because there is a lot of soldering involved
Gaui GU-344 - $75 RTF. no autolevel, but no messing with stuff. buy off ebay
Openpilot coptercontrol - $90. best in my opinion but they are hard to find
DJI Naza - $240. complete package. autolevel and everything
Hoverfly - $450. overpriced. but if you have the money it...Continue Reading

print out all the sheets for your frequency. It will help you make the angles. Straighten the wire, make the bends one at a time. Everything is measured 100% accurate so there is no measuring involved.

Cut out the 45 degree angle for the correct slope.

There are many guides out there but this is my take on everything after fumbling around with chinese electronics and soldering for hours and hours.

It is very hard to create one setup because everyone has a different budget and purpose. Some like flying high, some like low, some like flying super far away. Some people like traveling to different places for a new perspective on things(historical monuments are good for close range FPV as long as it isn't the White House )

I will try to give separate options for each piece of equipment.

Airframe
We will start with airframe. You should pick this based on where you want to fly and how far away you want to fly. Do you want to glide around up high or do you want to stay low and go fast?

Popular airframes:
Skywalker
EasyStar/Hawk Sky/Bilixer/SkySurfer http://www.hobby-lobby.com/easystar_rtf.htm
Twinstar

Advanced airframes:

Ritewing Zephyr and Zephyr II http://www.ritewingrc.com/
Super Alulah http://www.rcgroups.com/forums/showthread.php?t=1464792

there are also some odd ones in the fpv section.


Camera
Now you need to choose a camera. Get one from securitycamera2000 unless you want to spend $130 from a USA vendor. 520TVL or better, get sony super HAD II. I have this one http://www.securitycamera2000.com/pr...l-OSD-DNR.html

NTSC = america, PAL = europe
i like NTSC because it's 60Hz refresh rate vs 50Hz on PAL

Transmitter
Frequency choices are 900MHz, 1280MHz, 2.4GHz and 5.8GHz. You want 500mW...Continue Reading
