So I know this is an old thread but it has great info. I am trying to implement an arduino into an 80" skyaider. I have converted the gear mechanically already but the Arduino is a bit of a learning curve and was hoping I can get some help. I spent 2 nights reading Arduino for dummies and watching some vids but I am a bit pressed for time. I am in school full time at night and runnning a business during the day and my free time to learn Arduino is small at the moment. I did manage to buy an Uno and a motor shield and was able to diagram the layout of what I am trying to do. Just need some help with the code if someone can.

The goal is to use channel 5 from the radio to the Uno. This will use one servo to operate the retractable tailwheel and one motor for each retract leg. The main gear on a skyraider go up at the same time so no stagger. The tailwheel follows when the mains are up.
The motor shield will use a 3S Lipo and the Uno and Rx will share a NiMh. Is this wise or should I go with a separate batt for the Uno and RX also? I have a Taranis and need to pull the servo endpoints off the radio still but I can edit the code with that later.

It looks like I can use what has been posted already with some editing. Thanks for any all all thoughts and help.
