... but I admit this is a bad coding practice to not use { } here, one could add an instruction after the if block thinking he's still in the for loop. But hey, it's just my crappy testing code, not meant to be committed like that

Got it ! Those 3 CS pins can be used for simple 8 fixed frequencies selection, or as a spi bus:
www.flypix.co.uk/ftp/RTC6705-DST-001.pdf
Funny fact:
in the specs (5GHz Band Transmitter Specifications) it states absolute maximum rating 5725-5865 MHz, however in simple fixed frequency selection table it states it can go as low as 5645 MHz (CS: 011 Band E)
We proved 5645 MHz is working
I guess this is a typo and it can do 5625-5865.

anybody seen the Hubsan that is due to be released in 2014? looks very impressive and hopefully Deviation can adapt to all the bells and whistles that it has...
GPS Auto Pilot function
Compass sensor
GPS RTH
Stable Mode with GPS and altitude Hold
Flight time around 25 minutes
Failsafe to return home & Landing
Low voltage protection
TX (FPV TX or Normal TX with Hubsan standard)
almost sounds to good to be true but i guess we will see soon

The bug is very easy to reproduce:
Looks like there's an issue with the u8 A7105_ReadReg(u8 address) function, in hubsan_cb(), just add a single register read after sending frame:In theory this code should have no incidence but it is enough to lose connection after a few seconds (random).
I found that if you add a few nop loops here and there in ReadReg() it will work longer before losing connection.
Anyone with a H107D wants to test a firmware with (supposedly) working voltage telemetry ? Don't attempt to actually fly , there's a big risk of connection drop it's only to check if telemetry is working. Thanks, and happy new year !

It shows the correct voltage. I verified with a charged and a depleted lipo.
However, like you said...I lose radio link. Can not control the model. The video continues to transmit though.
Eventually, I lose the voltage telemetry too. Shows 0.0v when that occurs.

Thanks all for testing and suggestions !
Don't hook up your analyzer yet, I think I just found the trick, let me empty a few batteries to confirm it's working fine
