i believe Every 1980s RC lover he must remember at 1981 Tamiya 1/10 Toyota 4x4 pick up and 1982 Chevrolet Blazer you need buy a 4CH RC as it got a 3 speed gear box, semi elliptical leaf spring use wrong metal and wrong construction, the main leaf spring and second leaf both end joint together, wrong design this make the leaf spring can not work when got load. This make suspension not working!!! only i know this at 1982, I use clock spring to DIY, they are so realistic and in scale and soft for my Hilux and Blazer. Bruiser from 1985 to 2012 use 750 motor, new long leaf spring and front wheel one way bearing, no more manual free wheel hub at front axle, so good for turning but not good for off road, when truck use 1 st gear to reverse no front wheel drive! after sand go inside no front wheel drive any more too. Today Bruiser (RN36) and mountain rider use new gear box and 540 motor front, rear axle got diff inside, can manual lock, but take 15-20 min to do 2 axle lock or unlock , as the lock pin hole on the top of both axle, can not believe. but it is still fun at 80s.I got so many expensive Hilux at 80s and i DIY 2 in to 6X6 and one be semi track all leaf spring and hand made rear 2 axle with see saw automatic balance . on the read use middle axle drive, off road use 6x4, max deep mud or climbing at rock area use 6x6, it is so fun at 80s, you can see this at 80's Radio Control Magazing in HK and Japan. if you want to know more about Tamiya history go to vist our FB, it is Chinese but you can use google translate. TThis RN36 with open diff, after take out 2 leaf spring, it can go to off road, but not very good. but todays Battery so light, than you mst take out 2 leaf spring at each wheel, I believe need a new soft off road tire.
