Well, not sure why you don't want the RTR manual, although technically the RTR is a NT2, not an NT1. The XXX-NT Sport was the first actualy NT RTR Losi produced. The AD1 (Adam Drake 1) IS a XXX-NT, it all shapes and forms...it's just with graphite parts and no hard-anodized chassis. They didn't include a specific AD1 manual, it was an addendum sheet with graphite parts listed. The link is below:
Yes, the sport parts are a different composite than the original NT parts when the AD1 was out. Personally, I stay away from graphite parts on the NT, it's fragile enough as it is, and they actually hurt you on most tracks because they don't absorb the minor suspension flaws of the truck, whereas the composite parts do. Just my pennies, though.
