Yeah that emta tranny looks more complicated than the mt4 and not as easy to work on. With the mt4 you get a center diff so you can put 100k+ diff fluid so you can get the monster truck handling. I don't think the emta motor and esc are waterproof though, maybe water resistant.<div></div><div>yesterday I was changing the grease in my rear diff to silicon oil. It was late at night so when I put the diff case back on, I stripped 2 of the screws somehow I need to get a new diff case and use my dremel to cut open the old one. It could of happened to any car, it happens way easier on a 1/10 scale though.</div><div></div><div>I ordered lots of spares just in case because I'm going camping. Lets hope they arrive before Christmas....</div>
