I know it has been done several times before, but now I happen to have access to Rigger 3.
I could easily find at least Grendel's vehicles, which has the stats for an MH-60K Blackhawk. My main problem with that is that it's a Utility Helicopter instead of Cargo Helicopter, so it costs 4 times as much and is rather small, and it has a few other oddities (dunno what version of Rigger it's been done with). The small size doesn't have to be a problem, there's need for smaller transports too, but the Max CF of 75 is really pitiful: 3.125 x 2 x 1.5 meters is hardly enough for a squad of infantry, nevermind all the equipment.
A Utility Chopper is probably something like a UH-1 with it's 4800kg max take-off weight, just too small for a 10-tonner like the UH-60. And then I thought, if I'm going to design a military transport chopper, I might as well take it to the extreme to see if all aspects of it would work. So I set out to do something like a 2060s MH-53.
The following is what I came up with. I took a few liberties while originally designing it, and then had to tune it to get it back into canon. I'm sure there are errors in there, and I'd be really thankful if someone could point them out.

To the cargo area
-Handling improvement (-2)
Max available (5 -> 3)
-Improved economy (15)
0.2 x (1+15x0.05) -> 0.35 (km/l)

-Extra seating 2 buckets
-Winch 1000kg
Design Point total: 20731
Cost: 5,182,750
Street Index: 4
Load (pre-F-B-W): 8867
Could easily put in CMC-9, more enviroseals, 1pt higher Sig and higher Speed, CF and Acceleration etc. and it would still be far, far cheaper than RL military transport choppers. The MH-53J has a Unit Cost of $25 million (1993), compared to that this baby is a real bargain. With max fuel and all the weapons and ammo necessary (3 miniguns and at least 10,000 rounds, probably 14,000) it can still easily lug around an infantry Squad or two.
So, what did I do wrong? That would just rock too much to be real.
Next up, a smaller transport...
