I've been there twice - once 15 years ago and again this past July
I can honestly say it is THE best air museum I have ever been too - I'd say it is better than the Smithsonian's (but I like combat aircraft).
It has easily over 20 real cockpits you can sit in.. Here's my brief review I posted on Frugals this summer:
I had the wonderful priviledge to visit the Pensacola Naval Air Museum last week while on vacation in Florida, USA (this is the biggest Naval Air Museum in the country - I might start another thread to talk about it) and they had something like 20 or 30 cockpits from real jets/planes/choppers that you could climb into and sit in and tinker with stuff.
How is this relavant to IJ's mod? Well, I see a lot of people using it for prop sims, which it is wonderful for, but - for most US Aircraft (with the exception of the newest fly-by-wire jets like the F16), they have the traditional throttle/pedals/stick.
I immediately noticed one common theme when climbing into the Jet pits (even the Harrier and F14 had this) - which is how the stick worked.
They all had independent x and y axes. Basically they were a control column coming out of the bottom of the pit which made the Y axis, formed an L and a swivel joint about or just below groin level at the seat which then made up the X axis.
So as far as authenticity is concerned - I'd say the NXT is pretty darned accurate! Independent X and Y Axes, just like the real thing! (for most jets)
I'm pretty sure most guys here haven't had the priviledge to sit in many different jet pits (the real deals nontheless) and some many modern, so I thought I'd share that.
If any of you ever have the opportunity to visit Florida in the panhandle region, you MUST go to this museum. There is nothing else like it that I have ever been to - including the Smithsonian - it is that good. It is a aircraft nuts wet dream! I even got to touch a Sopwith Camel - that could still fly
If only I knew how to post lots of pics I would for everyone - and IJ to see the control column.
I think I took almost 200 pictures while there.. and quite a few of the pits of some of the ww2 birds.
