G'day Andre,

I just finished going quickly through the manual for the 120 KS. First I must say that the manual seems to be extremely well done. Compared to the other 3 brands of turbine engines that I have owned thusfar, yours seems more user-friendly - it's both easier to just sit down and read cover-to-cover, and easier to find specific topics. (No bash meant against any other brand BTW). The detailed "fault vs remedy" chart also seems well done, and from what I can tell so far, the user interface on the GSU is also more intuitive than I am used to. Good job !

I have a few questions, if I may...

1) The shutdown procedure outlined in the manual indicates that connecting the GSU is optional, but the startup section makes no such mention. Does this mean that the GSU absolutely must be connected for the start ?

2) The built-in charge system intrigues me, yet I'm not clear on how it works. You can apparently charge the ECU battery by connecting an external 12v supply to the GSU, and the GSU to the TCU. The RX battery can apparently also be charged in the same way... but how ? If the GSU is plugged into the TCU, and there is a throttle channel connection from the GSU to the RX, that still doesn't allow charging of the RX battery unless the RX battery switch is "on" .. what am I missing ? (i.e what is the connection path from the GSU to the RX battery ?)

3) Also re battery charging - does the system allow both TCu and RX batteries to be charged simultaneously, or just one and then the other ? If the latter, is it a manual switch-over, or can it charge the TCU battery and then switch over automatically to do the RX battery once the TCU battery is done ?

4) For RX battery charging, there was a mention that the charge rate must be selected. Does this mean that it's a constant-current charge, or is this a max rate, or wot ? Also, is this value entered once and stored in non-volatile memory so that it need not be entered again for the same system, or must the value be selected again each time ?

Appologies if the above is already detailed in the manual and I just missed it.
