Anjou: No sour grapes, just lessons learned the hardway!
Concerning the U/C STC.....not as simple as you make out, or as cheap!! Regarding the weights.....that is @ ambient temps of up to 24 Celsius. Then it really starts to dip! Max operating temp is 45 Celsius!! Have you A109E time? Then you would definitely appreciate the power management in high temp. Also, I side bar of this is the Perf 1 and Cat A performance.....goes out the window. You didn't include the cost of the Downtown Heliport, The halfmillion Dollar Helideck???? and a bunch of other stuff that we won't mention!.........................But if you think it'll work, why not join them?
