I took my et out for the first time today. Didn't turn out like i would have liked. First I had to reverse the throttle and steering on the tx which is no biggie. Then I drove it around and noticed that it wasn't nearly as quick as I thought it would be. Now I usualy run 5s but I started with 4s for the first run. But it seemed like reverse has more punch than fwd. so I'm thinking maybe the mmm2 esc needs some adjustment. Maye some things got messed up when I unplugged it and rewired it in this truck from my other truck. Any ideas there? Then I noticed a line of diff fluid under the cd. Now I asked this awhile back but when I tighten the spur down tight it makes it tough to turn and notchy so someone here said to back the screws of a little which I did and it felt a little better but now I'm leaking fluid. What can I do about this? I am just disassembling now to re build it and make sure I didn't miss something but so far it looks good. So the two thugs I need help with is the power issue (I am running mamba monster 2/2200kv with 16t pinion. It seems like the truck was doing maybe 20 mph. I had this same setup in my other truck and it hauled ass. And I also need advice on the center diff leaking and not being smooth turning.
