I’ve started flight tests with the latest Ardupilot code and hardware and will post my findings in this blog post. Info on my plane and set up can be found HERE. I’ve found the EG 2.2 has similar flight characteristics to the original EasyGlider including the same “reverse roll” and “reverse pitch” settings in the code so these results should help anyone flying the stock glider.A few notes on what I have discovered so far---The throttle immediately kicks in when you switch to WP or RTL mode. There is no “safety” coded into the throttle command such as, no throttle activation below a given altitude or a given speed, so be prepared if you switch from manual mode at the flying field. Also, in the .h file under Throttle gains the throttle_max variable is defined twice. I’m not sure which is used by the code. There are also some corrections to the manual that I posted HERE that may help others in their set ups. Good Luck!

agree, I tried and the throttle control doesn't work well.
I crashed my plane into a tree 2 days ago. After getting it down, then I have trouble uploading code to the ardupilot board. Then, tried to burn the bootloader with USBtinyISP, failed.
>David,
I bypassed the AP and plugged the ESC directly in the Rx for manual control. It was one less variable to worry about while sorting out the elevator and aileron issues. I had tried flying a few weeks ago with the throttle control in the loop and found out that was also going to take some time to tune. Hope you are still having success with yours.
Made some more good progress today and got her flying RTL and WP's (kind of). It was a challenge get the navigation and stabilization control outputs coordinated. Had to go in the code and make a change along with header file changes.
By the way, I rechecked my original log from the last flight and "walk_around" was set to 0 not 1 for my walking test (the correct setting) so if I just reverse the roll output from the IR sensors I should be good to go.
I haven't put mine in a plane yet. Who wants an AP that only goes east. But once out of range, it will still go east on RTL. That will put it east of me. Being in NM, that would put the plane in the high desert. Of course going north, west, or south, also puts the plane in the high desert. That's the advantage of living in the center of NM.
Oh, if it went south too far, it would be on the White Sands Missile Range. I think they may try to shoot it down. Or mistake it for an inbound Shuttle.

the throttle control is done by ardupilot or manually?

Jordi lives on the west coast I believe. If your plane got away, which direction would you want it to fly ??
NOT out towards the ocean !!
Hay Jordi, does my theory hold water ?
