Thanks for the manuals Phil2, one of the things I’m confused about is the chassis, all the Dunerunners I’ve seen have been the single steering servo setup but this one is a two. I’d like to go to a single but the area where it’s supposed to mount has a lattice of lightening holes there (pic). So I ordered a new chassis and it has the holes where the servo bracket mounts but it’s about an inch and a half longer than the one I have now. Another idea I’ve been bouncing around is possibly mounting the engine so the crank facing forward or backwards and somehow get rid of the center diff altogether. Just thought of that this morning so I’m bc sure there’s a million things flawed with that idea but if you guys don’t mind lemme know what y’all are think, many thanks..
