Thanks David. Can I remove the wires from the receiver board and use the connector on the adapter board?

And what about the gyros?

That adapter will allow you to have a backup battery (capacitor) attached to the board.  I have two of them and they work just fine.  This is also the reason that the wires are not very securely fastened.  There is no way to do it without removing that male adapter.  So that just leaves attaching to small resistors and capacitors.  When I return I hope to have some of those boards made.

Good evening everyone,

first of all - huge thanks for all the work you guys have created! It's amazing how professional things can be done in opensource way. I have some questions, maybe you could help me out a bit.

I was looking for a cheap gyro, and came up with this one:

It seems to have analog outputs, and 2.7-3.6V input. I don't have a good knowledge in electronics, so I would very much appreciate your professional oppinion - would it work with TWOG? As far as I understand, I will only be able to use two channels, as I couldn't find anything about third axis (YAW) gyro configuration in airframe file. So maybe two of these would be a better choice?

Also, I saw that the recommended gyro (ADXRS613) has sensitivity of 150deg/s, and the above ones have double of that (300deg/s). How would this influence the performance?

And last, but not least - I'm changing my GPS receiver to "LEA-5H with Active Sarantel helical" (from CheBuzz). It doesn't have internal battery (so it starts up longer), and it came with wires ripped off. The latter is not a big problem, but I've found this adapter, that might solve both issues:

Do I get it right - if I attach this adapter to my GPS receiver, it would enable it to hotstart, and to have a more convenient cable plug?

I have way more questions left unaswered, but I'll stop for now, as I haven't read EVERYTHING yet :) And thanks in advance for your support.

Rokas Adiklis.
