Hi Jerry,
Nice to hear from you again. The software update is for the KS series, I think you may have the V1 Gas/air-start BMT80. There is an upgrade for the 80 as well. If you want I can mail you the latest but you may need a ISP programmer to get the code onto the CPU. The KS of course loads direct from your PC.

SAP2000, the wings have quite a bit of volume. 80% of each wing has a skin to skin fuel tank with 4 cells each devided into 4 again for a total of 32 cells. Because the wing has no spar or ribs the tank also helps the structure a bit as it is bonded to the inner skin of the nomex/carbon layer. 4 fuel pumps in total manage the fuel system via 2l header tanks, one for each engine.
The UAV is quite big with a 2.3m span and 1.2m chord and 9% laminar flow wing about 95mm thick at the root. About 2,5 msq of wing. Amazingly the fuel does not move the CG near as much as you would think.
Cheers
