Well, for starters, if you get the right main radio you don't need a second radio for pan-tilt. Get one with dials/sliders for at least two of the aux channels, and you can use them. ArduCopter really only needs 5 channels (although 6 are handy), so most 9Ch RC setups will work. If you're looking for a cheap one, the Turnigy 9Ch works well.

Yep like Chris said, 8+ channels gives most out of the whole system. If you get 7ch you will notice rather soon that you would like to have at least +1 channel more.

I'm using that Turnigy 9x radio with 2.4Ghz modules and it's great radio for this type of use. Have all normal 4 channels on sticks, 2 channels on switches to control flight modes and 2 channels on knobs to control camera or something else.

ArduCopter software has internal camera tilt/roll and pan/tilt compensation system build in.

If you have radio controller and video system on same frequency area, you might end up on problems with your radio range due excessive interference. So try to get video system that uses 1.3 Ghz or so... If you have 1.2Ghz video system it can also create interference due harmonic frequencies.

Hey Jani, you legend,

can you point in the right direction on how to set up the Camera pan-tilt system with the Arducopter?

I've got the Turnigy 9x as recommended, as waiting for HK to get Pan-tilts back in stock....again!

thanks very much!

Owen

Hey,
get as many channels as possible. You never know what the future holds.

Get the cheap and really great TH9X from hobbyking.com for about 60$ and 8-9 channels.

Get 5.8Ghz for FPV/video equipment: This one is really great and cheap: http://www.himodel.com/electric/FPV_5.8G_200mW_A_V_Transmitting_rec...

Can you list the programming values for the Turnigy 9x radio for use with arducopter. I am awaiting the arducopter kit, and would like to set up the 9x to use with it.

Hey,
I have no idear. I guess if you just want to fly you don't need to change anything, because you just need 4 channels to fly the thing.

If you want to use the 3-way-switch you need to setup the mixer. I use a different firmware for my TH9x. For that I installed a permament 10 pin cable that will fit on my usb programmer.
You can find the firmware here: http://code.google.com/p/er9x/

If you flash this firmware I can tell you exactly what to change so you can use the 3-way-switch.

Where do you life? I wonder if I should get the whole package for 499 or just the electronics to put in my already build quadcopter with roxxy engines.
Nearly every gib package from outside of Germany will be hold up in customs. They will charge me 23% for tax(19%) and customs (4%). This is a lot of money.

How do you deal with customs?

Hi Cybercrash

I too have a 9x TxRx.

Which re-flash version would you recommend.

Does this firmware enable you to map any of the switches (TRN, THR CUT etc) to any of the channels?

This would be a great advantage as I would prefer certain switches for certain functions.

I tried to find something to read about whether this was possible but have not found anything yet.

Thanks

John, i'm currently working with turginy radios and testing different firmwares for ArduCopter use. I should have some reports about those in week or so. Er9x is one most promicing but even that have some problems with center stick areas and scaling whole stick movement so we need to do patching to it.

Hi Jani

Thanks for the reply - I'll be keen to see the results of your firmware tests.

I'm still looking into the best way to program the 9x at the moment, the hardware mod or the plugin mod which I think will not be available until next month.

Again thanks

Thanks for the information guys. I noticed the Turnigy 9 has 2 modes that can be purchased (currently backordered). I have poked around on the internet a bit but there does not seem to be a clear answer, and Hobbyking does not give a description so what the heck does the Mode (1,2) mean and what one goes with the quad project?
What are others using for the telemetry? the 900MHz or 2.4GHz?

Hey,
you should google for the info.

But in short: Everybody uses Mode2. Mode1 got switched left and right stick.
Get the Mode2 and look for V.2
