Hey guys fairly new to the rc trucks scene and I picked up a used terremoto v2. After several hours of browsing with minimal luck, I was wondering if anyone could help me or point me towards info on if it has part compatibility with any of the other 1/8 redcat trucks. I see redcat has several 1/8 scale such as the MT8E, Landslide, Kaijin, and the Earthquake 8E. I've even heard of possibly some 1/6 Shredder parts fitting. Main reason I'm asking is I'm looking to beef up some of the weaker parts and have some extra on hand for when things did eventually break. I've heard redcat uses a hard to find pitch (1.5?) when it comes to gearing and the stock spur gear is plastic while the pinion is brass. Any info or directing would be appreciative!
