Glad you finally have some time with the early board (SN 4 )

1. Yes you need to short both solder jumpers
2. I don't really know about your ICD2 programmer, but mine (a "fake") has only 5 pins. The innermost one is VPP.
3. Yes
4. Yes and yes
5. The 5V one
6. Yes

I only have the 3.3 volts sparksfun ftdi adapter. Can someone confirm whether you have to have the 5 volts one ?

The board has 3V3 and 4V8 regulators for the sensors, gps and microcontrolle. The 5V is directly fed to the PWM/PPM pins (so be carefull when you want to use a higher voltage).

So you can supply your board with an external 5V, and remove the red wire from your 3V3 FTDI cable.

For the sparkfun ftdi - just make a 3 wire cable with gnd, tx, and rx. Later on you will see the sparkfun board interferes with the gps connector so this will also avoid future problems.

Mitch, what do you mean by "Later on you will see the sparkfun board interferes with the gps connector"?

The sparkfun ftdi board is set up to plug directly onto a header without a cable. Very nice except one can't isolate the + wire. Also the sparkfun board will overlap the gluonboard gps header when it is used this way. Not a problem with the gluonpilot board - just the geometry of the sparkfun ftdi. My solution is to simply make up a 3 wire ftdi cable to connect the sparkfun ftdi to the gluonboard header.

THanks Tom. I will stick to airplane till you return from vacation. Congrates on the navigation done. WIll download and give it a try..

For those interested: I added the quadrocopter firmware version. Example config file here.

Thanks Tom..

Tom,
Can you also give some more details on the servo out connections to the motors..? Like ch1 should go to motor 1 (which motor to consider as motor 1 ? ) etc.. I am assuming you do not need any mix in the transmitter. A connection diagram to the motors from gluon with the config above would greatly help.

Do we have yaw stability also in Quad or yet to do ?

Hi Sid,

I added the connection diagram: http://gluonpilot.com/wiki/Quadrocopter

The version in the download section has "yaw rate control". Yaw will slowly drift but you can control it. A previous version had absoluteyaw stabilization but no control.
The next version will have absolute yaw stabilization and control

I haven't found the right PID parameters for flying in winds (but I'm getting there). The ones you find on the forum are for wind-less evening weather.
In the beginning, you should always fly in no wind.
I had large stability bars to prevent broken propellors, if you don't have them you might need to make those P-values 30% smaller
