Peter, "Old style" body posts ?? Does the car come with something different ?? Didn't know they had changed at all since way back when. My MI3.5 still used the same old part numbers I think. Did you fit a Lipo in to this chassis ?? How did it fit and do you see any problem with using the hard case packs with the humps on the bottom ?? Also, How does the gearing situation look ?? I don't think the original Mission would allow for the kind of pinion/spur combinations we need now with BL motors but I could be wrong.
