This beta brings support for the new MediaTek GPS unit. The MTK works great and it's very light.

I've also added some bug fixes including:

  • Auto Trim - (on by default) When you enter any flight mode from Manual, you'll save your current trim values. Great for trimming your plane in the air.
  • FBW issues (turning too much in one direction) caused by incorrect or unset radio limit - fixed with new algorithm
  • Radio Mixing - lowered the mix value for more responsive sticks
Let me know if you have issues, and I'll update the release version.

Thanks for testing!
I'll look into those things tonight.

Thanks jason, great work. I'm going to add support for your two way telemetry to my gcs. Out of interest your gcs seems to have raised some interest, have you considered a small c# app that can create a serial proxy and then fire up your app? Am I being too simplistic?

Christof, great testing thanks. Where can I buy an easglider special? Thanks

I'm not really able to produce such and app, but I'd be open to it. The Flash app has many limitations though! I can't save Telemetry to a file, or view google earth, or view maps offline, etc. I think you'd be pretty disappointed with it in use. I am going to start playing in Labview and QT soon to see what I can do with a real app dev environment.

Hi Jason I tested the newest release today and the issue of different bank angles in FBWA is fine now. AP and FBW work very smooth.
I will try Autotrim next time.

Airframe is a Easyglider special
AP with IMU V2 and Airspeed. .h File attached. Photo attached.AP_2_6_header.h

I was testing some other things very intens.

FBW B has no throttle response/output at all. I could use FBW A only.

If throttle is reversed on the ESC and AP is set for Throttle_reverse = 1 the AP goes into LOITER as soon as I switch to AUTO, Throttle works the wrong way.

LOITER has problems with radius 20m and 25m. The plane describes almost an 8 although it does not change direction. It seems that the bank angle is to big and the turn radius is to small. So the plane turns and after 80% of the Loiter it moves a bit to the outside of the circle and then describes a new 80% circle.

When I had Loiter Radius set to 15m the plane described an 8 but since I changed many params in speed, roll and bank.

Thanks for your exceptional work.

jason, well i look forward to your qt work :)

Thanks Jason

The EasyDrohne is a simple Easyglider from Multiplex. I was looking for a bit a bigger airframe than the Easystar and pusher. I bought the Easylider and made some drawings. Cut off the fuselage, cut off the wings, add some carbon 8mm tubes to the remaining wing. Add two stabilizers in the rear and glue the elevator on it.
Unfortunately you would have to build it yourself. And btw it flies great and there is plenty of room for video and Tx. Just keep the angle of incidence difference at ca 3.5°

Thanks Christof, I'm not very good at building or drawing :) but it is something for me to strive for.

Please keep up the great testing for jason and the rest of us

Thanks Jason for the latest release !

Thanks Chrstof, for evaluating and throughly testing the latest release !
You have done a very nice creativity of conversion of Multiplex Easyglider, it looks so beautiful !

An thanks a lot for sharing your options.h file !

@Jason, lewts us appreciate the creativily work done by Christof and finding the bug as well !

My description of the LOITER is a bit weired in the last comment. I extracted the .KML portion with the potato LOITER maybe that helps for a bit of advice from you.

Thanks for the flowers....
