Hallo,

I am a bit new on UAV and like to buy a total sytem to make the gaui 330 i did buy stabil and most of all save. I mean that i can make preselections like return to home fly to waypoints and autoleveling.

I supose with the ArdupilotMega 2.0 i will have a total syteem.

I like task why the external compas is need for.

I also like to ask about the telemetry kit why that item can be used for. I supose to give instructions direct from the laptop. Is there need for some more items to manage that.

Can somepeople with more expierience give info nabout that.

Or if there are some extra's needed to have a excellent result let me know.

 

Willy

@Cory,

     This kit from the diydrones store has much of what you want.  I'd recommend starting with that..plus perhaps the sonar, get that working and then add the telemetry and camera later.

     The code is pretty stable but everybody crashes eventually.  They're more durable and cheaper to repair than a standard RC helicopter..but still, you'll likely crash so you better be prepared to buy some spare parts.

 

@Willy,

     You need the compass for loiter (i.e. position hold) and way points.  Basically for any kind of autopilot type function you need the compass.  It can't rely on the gps for direction (like you can see in your car) because quads can go in any direction and a gps actually calculates the direction, not from the way the quad is facing but from it's direction of movement.  You really need a compass.

I was thinking about a board to make my guai 330 UAV or/and  to use on a plane.

Lets say when i buy a ArdupilotMega 2.0 and a compass i can fly UAV i supose.

About telemetrie, yhis is a system for comunication with laptop as groundstaion i supose.

Need a camera with goggles a extra telemetrie or is that posible with the same (Xbee)

Thanks Randy. That was the kit I was looking at getting. Is there anything else I need to buy along with that to have a fully functional multi-copter? Additionally, is there a camera setup you'd recommend for live video? Thank you!

Hallo,

What is the result for using a(1 ore more) sonar with ArdupilotMega 2.0.

You want range over a mile? What are you planning to use as a radio to control it with? Most of your normal 2.4ghz systems are not going to work if you are trying to control it that far. Same with a video transmitter so that you can see the live view off of your cameras, if you are planning on flying that far away you will definitely be trying to fly it via the view out of the cameras so you had better have a pretty reliable video transmitter/receiver. 

None of this is cheap. The dragonlink tx module and rx is one way to get that kind of control range, but that alone is going to run you over 500 bucks. Plus a transmitter to put them into. 

Also - over a mile in range, most of the multi rotor copters fly for about 8-12 minutes depending on payload being carried (cameras, video transmitters, battery size, etc).  And they don't fly fast, 15-20mph maybe. So you aren't going to get all that far away on a single flight unless you try carrying lots of really big batteries, which reduces the amount of payload carrying capacity to use for cameras and such. 

You mentioned keeping the cost low. What is low to you? Given your goals I would expect to be spending in the $2000 range at least.

That question was out of curiosity, I just wasn't sure. Depending on how into this I get, it might be something I would have wanted to look into. However, I just need to get started first, and really, I'm more concerned with the live video rig.
