Why i put 40 weight, AI answer. For a stock 1/16 scale Traxxas Mini E-Revo, the recommended shock oil weight is 30-weight. However, users often upgrade to a heavier oil like 50, 60, 70, 80, 90, or 100-weight for improved performance and reduced chassis roll.
They sell upgraded springs; they list them as green, black, and purple, but I don't see a description of which ones are stiffer. I'm going to do some research. But I will reduce the preload on the front like you said and run it for a few batteries tomorrow. I am new, so I am in training mode. I will let you know how it works out, but I will also check the oil in the shock, as you recommended. They were low before. Was it a leak or a factory error? We will see. I did all the upgrades. Recommended on YouTube, which was probably my bad, resulting in wasted money. Found the diffs with very little oil in them. Thanks for working with me. My wife ordered a Maxx for my birthday. I am a retired military veteran in my late 60s, trying to keep busy. I enjoy the complete teardown and rebuild. Hope I am going down the right road with Traxxas. I'll give you a break for now. Thank you so much.
