I have a RTR brushed E Maxx. I bought this because it is water proof. They were right! I drove this in a local lake several times! Yeah Buddy! This is my first E maxx, but 3rd traxxas monster truck. My first T Maxx was the 1st gen pro 15 from 2000. The 2nd T maxx was the 2.5 2nd gen version that I hoped up and put an OS 40 four stroke and spent 600.00 extra on the build. It never performed like I wanted. Soo much money and soo little fun really. My question to you E maxx owners and racers is, what aftermarket parts are really worth putting on the truck evan prior to its failure? I want to keep the truck water proof still and also keep as stock as possible. What brushed motors would make this truck better? I was thinking of a pair of hand wound corally black motors. Any advice would be great.
