"MUX light seems to work ok from memory. It seems to flash in tandem with any twitching of servos.
The MODE light also seems to be ok - it goes on/off as expected with 3-pos switch on Tx.

Is it ok to remove jumper _whilst_ the blue light is…"

"Re-soldered the machine pins for the Rx-->Ardupilot inputs and the rudder is now working.
Still getting what seems to be a servo frenzy when Autopilot is off however (I am using 3-position flap switch)

The IR calibration process is a bit cloudy for…"

"Ok, well I win the Darwin award this year. Rx --> ArduPilot cables were the wrong way around (I had the signal cable on the -ve pin!)

Got elevator control but no rudder yet."

Not the best picture!

Is there a simple way to check control is being passed through? I'd like to plug in, e.g. one servo and check it works, then plug things in one by one until it breaks!

Old…"

"When the blue light stops flashing, it does not remain active.
My rudder and elevator servos go into a state of Frenzy for a few seconds and then nothing.

Also, from my Tx - I cannot move any surfaces at all, at any stage of the process. So I'm…"

"Problem solved.

The USB cable was faulty. I have now uploaded ArduPilot 2.1 to the board.

Time to start tinkering!

Thank you for all the tips!"

"Hi,

I think I need to burn the bootloader onto my new ArduPilot board.

I have the FTDI breakout board but it sounds like I need an AVR programmer.
I found an AVR programmer in the UK, but i'm not sure if it is compatible..…"
