Well, to be honest, I acctually think the Pitwork is a better handling car than the NSX. I have tried running it and then running the NSX on the same codes and settings and the NSX just cant take the turns the way the Pitwork Skyline does. As far as comparing the Pitwork to the Trueno, Its hard to say because you have different steering mechanisms interacting on each car, So basicly they each have good points and bad points which I have detailed in my other posts. OK, The way the height works is simple, Ground clearance is the same, The top of the car is what changes. The NSX is only slightly over HALF as tall as the Trueno, While the Pitwork is very close to the same height as the Trueno. The Trueno is about the same height as the Beetle or the Lancer. So The height isnt a big factor here. I have also noticed that while all the "Rs" Pop major wheelies on take off using the 8138 setting on the Special controller, The Pitwork is actually capable of jumping over my mousepad and mouse cord on my desk! If the car is about an inch and a half away from the mouse pad and you pull the trigger all the way (Special controller only) It will pop a wheelie, hit the edge of the mouse pad with the rear wheels, lift about an inch high and shoot over the mouse pad and mouse cord. It usually lands on its top, BUT it is still alot more than what the NSX or Trueno can do. When I bought the Pitwork it was because I wanted to have all the "R" cars, But after playing with it I am very glad I got it. I hope this answers your questions. I havent received my RX-7 yet. It is set to be delivered on the 11th. I will post a reveiw on it then.
