Indeed very nice. thought about it several times but:
Huey skids ARE very solid. I doubt that they "flex" noticeable and I am not sure about "gear compression" on skid contact points. I remember almost 100% that this is not possible (we tried something with the flexing wings of the discus wich have skids)
If by "solid" you mean they have zero deflection under normal operations, I disagree, based on personal experience as a UH-1H crew chief in Viet Nam. From my vantage point in the "well" (alongside the transmission facing out and behind an M-60), there was visible outwards latereal motion as the weight of the helo was transfered from the rotor disk to the skids. Granted, that flex was all in the cross tubes, but the point is that the skids as a whole assembly were not completely rigid. Another way you could see it was when we'd hoist the entire helo with a 5 ton wrecker (big tow truck) to perform maintenance on the cross tubes, saddle straps (what holds the cross tubes in place) or replace a bent skid. I no longer remember the difference between dimentions with the ship suspended and when the full weight was on the skids, but it was easily measurable. Indeed, the maintenance manual (US Army TM 55-1520-210-20 - the organizational maintenance manual) contained skid-to-skid maximum dimention limitations to acount for hard landings and the resultant permanant deformation of the cross tubes.
That said, I honestly can't see a reason to program this motion into the sim. I'm simply trying to point out that the landing gear (after all, that's what it is) is not a perfectly rigid structure.
As an aside, while I no longer have my -20 maintenance manual handy, I still have a vintage (May 1969) TM 55-1520-210-10 Operator's Manual for the UH-1H. I assume you have access to one considering the masterful modeling you've done, but if a loan of several months would be of use (check lists, color performance charts, etc), just PM me and I'd be happy to get it into your hands. I'm really looking forward to flying an old friend.
