Need more RC practice

Here the picture, before I crash it.

I'm too afraid of crashing my Bixler which I want to fly wit paparazzi.
This is a Slipstream 1m wing from flyingwings.co.uk. Should be fun, when the wind dies down.

Serial mode telemetry

I tried with transparent serial mode telemetry through the FTDI adapter on the FlossJTAG. Works just fine.
Perhaps my modems have a problem...

Exercise your hinges

I learned a important RC foam flyer lesson.

Exercise the control surface hinges!

Those foam hinges are very stiff. Your servo will have a very hard time deflecting them. And sometimes they warp rather than actually deflecting the whole surface.
So, wiggle them until they get a bit floppy.

Telemetry fuuuuu

XBee telemetry is super unreliable. When it works, it's a dream.
But so often I just get nothing. And neither combination of resetting XBee, Autopilot, usb-port or link-server help.
I'm frustrated.

[Update]
I think I know what happened. I had for some reason set  NO_XBEE_API_INIT. Stupid me. So it ran effectively in transparent mode.

Spektrum

Spektrum receivers work. I actually forgot how to bind the damn thing.
