So on a recent trip to the field with my quadrotor I had a lot of requests for information on my setup and links to more info, so I decided this would be an easy way to post it up.
My transmitter is an FrSKY brand the model is "Taranis"
I bought it from aloft hobbies http://www.alofthobbies.com/
They are really popular right now and so there is a few month long waiting list, but hopefully production increases and they become more available.
The autopilot in my quad is an ardupilot 2.5+ the current version of this is the ardupilot 2.6 which you can find here www.diydrones.com If you want to read about using this autopilot check out www.ardupilot.com You can also find the same autopilot sold as the "megapirate" on hobbyking or the "readytoflyer" on readytoflyquads.com
