"Has this been answered yet? I'm looking into it too."

"Hi Adam, I am using ailerons not rudder. Rudder is not really needed in this plane. If I ever build another one I will probably not have an active rudder. It just adds weight! The dihedral in the wings keeps the plane very stable in turns, and it…"

"Are you using ailerons on your Skywalker? Has anyone flown it with rudder and elevator only? If so what were the results? Thanks Adam a"

"I should add, the plane is also very quick and easy to build, although it comes with no instructions, none are really needed. You will also want to reinforce the wings with carbon. There is a thread on rcgroups about this."

"Hi Mark, I'm currently flying the skywalker with ardupilot. The skywalker is probably the easiest plane I have ever flown. Its a real floater. Perfect for a beginner. And so far it is proving to work very well with ardupilot. That motor…"

"The US has export regulations. I'm not a lawyer but I think it just makes buying/selling ardupilot much easier if one party isn't selling everything."

"Mauro, I'm not sure about the GPS but you can't buy the Ardupilot mega from the DIYDrones store. You have to buy it from sparkfun. They do this to get around the restrictions on selling autopilots."

"Update: The shipping to my US address (in Illinois) is approximately 50USD. The wings cost 30USD each. I can buy up to 4 without having to pay additional shipping fee. If I buy 4, its about $50 each. If anyone in or near Illinois is interested, let…"

"I emailed the company and finally got a response. From what I understand, you can buy a single one for $30 but the shipping method used would cost the same for upto 4 wings. Due to this, you save the most per wing if you order 4. I'll let you…"

"Thanks a lot. I look forward to trying them out. I'll PM you my email address and you can email me if you need anything."

"No. The US, but I'll pay for the shipping."

"Chris, the arduino mega costs $60. How are you guys selling the ardupilot mega (arduino mega + extras) for the same price?"

"Thanks SgtRic and Chris. I understood it wrong. I thought you needed both the Arduino Mega and the Ardupilot mega. Glad to hear you don't need both and that the Ardupilot mega is the arduino. I just saved 60 bucks. While we're on the…"

"Mauro, you need the Arduino Mega, the Ardupilot Mega(from sparkfun), and the Shield(as shown in this post). You also need a GPS and xbee for telemetry. The shield has all the sensors, the ardupilot mega is the actual autopilot, and the arduino does…"

"What's the best place to buy this in the US? I can't find it for ~$50"

"I've read a few stores on them breaking. This will be first RC plane. I want to learn and practice flying it first without the autopilot and then install the autopilot. I'll try to choose between the Easy Star and the Skywalker. For a…"
