If you're like me, you've been asked plenty of times if your RC unit can be controlled by an iPhone. Now you may be able to answer yes!
Hobbyking IOS & Android 4CH WiFi Receiver
Four channel, talks over wifi, app works by pseudo-stick or tilt control, mysterious reference to "video function", failsafe... seems pretty nifty!
It looks like the unit joins a hard-coded network name, and the password is printed on the receiver.
Reference manual here. The Internet believes this to be the app.
