Today everybody and their dog seem to be working on a quad project. And with my own quad having reached a relatively mature stage with stable flight some time ago, I thought it would be nice to try something different.

So inspired by the full-size Osprey tilt rotor design I just started an experimental duo/tilt copter build. Frankly I am far from sure…

This is my first post to diydrones.com.

I think that it would be very nice to use same ArduPilot software in real life and with simulator.

So, according this blog post http://diydrones.com/profiles/blogs/the-ardupilot-fg-control-for

I have modified ArduPilot so it can be used with Flight Gear Simulator.

The next mod to my Easystar, a larger rudder made out of balsa and installed with dubro hinges.

There seemed to be 2 main ways to increase the performance of the rudder on the Easystar the first would be to just extend the length of the current rudder and the second would be to increase both the height and the…

I found the Fuse to a Sky Fly Max at a local hobby store and was instantly forced to buy it. It's a great, but simple starter plane which I think will make a great UAV.

Like always, I will not buy an RTF so I'll need to part it together, but that should be less than $65. for just the air frame. I have a few ideas to make it more me, but that's for…

I'm sure this has been discussed here before, but past posts seem pretty well buried now.

I've been giving some thought as to whether rudder or aileron (in isolation of each other) is better for initiating turns via autopilot control. As a bank-and-crank RC flier (it wasn't until relatively recently that I learned that the left stick on my transmitter could be used for more…
