    Really hard to stay away from this thread. I've watched each one of the flitetest videos and looked at all the parts list links. Seems pretty straight forward for the H Quad build. If I'm not mistaken the single most expensive item will be the transmitter but looks like a decent unit can be had for a few hundred bucks or less.

    There are some pretty inexpensive transmitters out there...and they get some pretty good reviews.

    Read the reviews and decide for yourself. I'd try one at that price. I found a used Specktrum otherwise I was going to try a Turnigy.

    So.... I bought the QR Ladybird with a devention Devo 4 control. I can't get it to sync. Youtube has nothing and I can't figure it out. I follow the directions but it won't change the tone or blinking lights. What am I doing wrong? I know it has to be easy...
    Thanks!

    How close to the LB are you when you're trying to bind? Try starting the binding sequence and then move away about 6-10 feet. I have to so this with my DX7 and the MQX for it to bind properly.

    You may have to adjust the battery position (if it's adjustable) or the trims on the radio.

    I unplugged everything again and let it reset. It now hovers and flies (and crashes!!!) I think this could get fun....

    It's fun until you start nose-in hover....then it gets frustrating!

    Damn! I could use one of those to carry my beer after I've had a few to many :clap

    Pretty sure mine won't be quite as complex :D

    I'll work on that next!

    I have crashed about 100 times this morning. And it seems sometimes better to lay it down when out of control. (I hope this statement doesn't derail on otherwise excellent thread!!)

    Took mine out for a spin this afternoon! This is flight #15 for me on this quad. I really like the way it handles. I want to build a strictly aerobatic quad next - this is my camera ship.

    I've narrowed it down to 'earth'. Or 'Baltimore'.
    I don't need another hobby.

    I don't need another hobby.
    I don't need.....screw it. :D

    So I've never done anything remotely like this before, but here's what I think I need for a quadrotor.

    Frame (1)
    Motors (4)
    Props (4)
    ESC (1)?
    Transmitter (1)
    Battery (do I need one for each motor, or one battery for all four motors?)
    Wiring (assorted)
    Flight Control Board (1)

    If I want to add FPV, I need;
    Camera
    Transmitter
    Battery (or do I use the same battery that powers the quad?)

    If I'm going to fly withOUT FPV, all I need is a receiver right?
    If I'm going to fly WITH FPV, then I need some way to watch the video as I'm zipping around, right?
    Should I use a tv (I'd have to go find one), or (preferably) my netbook, or my iphone (best possible answer)?

    Am i missing anything?

    Thanks for your wisdom.

    You need an ESC for each motor

    1 battery of the correct size and voltage is all you need, but some will run 2 batteries in parallel to extend run times.

    Props...you need counter=clockwise and clockwise

    You need a receiver for the aircraft...some use 2 (satellite receiver)for cheap insurance

    You'll need a LiPo charger (don't skimp here) and something to power it (usually 12-35 volts with sufficient amperage to charge whatever packs you're running)

    Of course you need another hobby!! Damn, beat to the reply by bigziff. I'll pretty much repeat what he already said.

    4 props, but make sure you get 2 right hand and 2 left hand rotation. They're cheap, get a few spares. You'll need them. :1drink

    4 ESC's, 1 for each motor.

    1 battery will drive all 4 motors, but you'll probably want at least two so you can be charging one while you're flying the other. Oh, and a charger to charge them with.

    One transmitter, one receiver, one flight control board.

    Plenty of patience.

    I wouldn't even think about adding FPV to it just yet until you are fairly proficient at flying line-of-sight. In addition to a HAM license, you'll need an airborne camera, transmitter, and battery pack. On the ground you'll need a video receiver and something to display it on. Goggles are popular, but a small screen would be good too.

    If you've never done anything like this before, I would really encourage you to start with something like a Blade MQX first. http://www.bladehelis.com/Products/Default.aspx?ProdID=BLH7500

    For 150 bucks you get a box with everything you need to get flying. You'll be in the air in the time it takes to charge the battery. If you decide you really like it, then by all means invest the hours and effort to build from scratch. If not, then you're not out a bunch of time & money.

    Ok, 4 props, 2 left handed, 2 right handed. Got it.
    4 ESCs, got it. The ESCs are wired into & controlled by the FCB, right?
    1 receiver for the quad, maybe a second one as insurance.
    Battery (12-35 volts), spare, & charger. Don't skimp.

    I understand that I should buy cheap rather than build first, but I'm reeeeally kind of in love with the idea of zipping around on FPV. My plan is to build the frame, a wooden one, according to the video on Flitetest, kit it up and zip it around by line-of-sight - then add the FPV when I'm comfortable with that.

    Am I missing anything else?

    I plan on just ordering off the Flite Test's H Quad build website page. Seems like they have taken a lot of the guess work out of what parts are needed.
