Hello everyone and welcome to my E-Maxx Build thread. I am new to this forum and thought I would start off by posting my progress as I build my E-Maxx. I recently acquired this completely stock 3906 E-Maxx on Craigslist for a cheap price. When I bought it I could tell that the truck had not been run in a while and would need some work. I decided that I would start replacing parts, as they break, with aftermarket parts that would be for a 3903/05/08 E-Maxx. So this is basically a 3906 to 3908 build.
Here are some pictures of the truck now. For some reason, the guy that I bought it from decided to paint the entire truck yellow on top of the body, I have no idea why.
Note: The truck is partially disassembled in these pictures because I am working on it.
Hi and welcome.
Congrats on the new truck.
I too recently joined here and also got a good deal on a lightly used 3906.
Good luck with your rebuild.
Welcome to the forum and congrats on your new truck. There a lot of very knowledgeable people on. This forum. Anytime you have questions please feel free to ask

Awesome thank you everyone for the welcome!
The day after I bought the truck the EVX started to act funny and seemed to be stuck in
programming mode or something else. I took it up to my LHS and no one was able to figure out
the problem. Instead of buying an EVX-2 I decided to go brushless and get the Sidewinder 8th
System with the 2200kv motor. When I bought it I knew it would destroy my truck, especially
my drivetrain, but I plan on upgrading it, so I'm not too worried. However, I did dial the
ESC down a bit and I am only running NiMHs with the truck as of now. I am loving this system
in my E-Maxx and even with NiMHs the battery life is really long!
Here are some pictures of the Sidewinder 8th-
The I had to dremel the side of my transmission case to get the motor in but it was only a
Nice one. Will have loads of fun with that system
Some of you may have noticed the different steering servo, I swapped out the 10 year old stock servo that barely worked for a Savox waterproof servo that I had laying around. It increased my steering a lot, but I probably need a new servo saver / steering system. If anyone has any recommendations for it let me know, I am using only one servo.
Well right now Im not having any problems with it, it is very fun and the batteries last a while on it. I am running NiHMs on my truck and I have the speed dialed down quite a bit because I need to upgrade my drivetrain. It will be about a month before I upgrade my truck to handle LiPos and more speed but so far I haven't had any problems
Ok, so last week while driving I snapped a stock rear driveshaft. Considering that I
wasn't putting very much power or torque into the E-Maxx I was very suprised. Instead of
just fixing the driveshaft I figured that it was time for another upgrade . I had the
older style short-armed E-Maxx and I was tired of that.
I ordered Traxxas CVDs, Traxxas E-Maxx Axle Carriers, Traxxas E-Maxx Turnbuckles,
Traxxas Rod Ends, RPM Rear True-Track Kit, and RPM A-Arms (x2).
The Traxxas CVDs fit fine on the older differential (I have a feeling I will be upgrading the
diffs and bulks soon anyway).
I installed the rest of my parts onto my E-Maxx without very much problem. The CVDs kept
popping out of the drive cups in the front but I fixed the problem by tightening the axle
carriers down. If it keeps happening I may get the extended drive cups for it.
My truck is really coming together now, I am happy with this upgrade and it made my 3906 a lot wider! Now what I want to get is a new chassis, probably
FLM, and the new E-Maxx transmission.
This is a little off topic but what camera are you using lol. Those are pretty clear close up pictures.
Looks like your build is coming along very nicely
It is a GE A1250 Digital Camera. It is a cheap camera that I got a few years ago and it is pretty nice :P
My shocks are sagging a little bit even with 55wt oil in them and I am wondering what I should do. I would rather not spend 60 bucks for big bores just yet. I have heard that Losi 8ight blues are good... does anyone have any suggestions?
Ok so I ended up ordering a few new things in preparation for getting a new chassis. I got
the new transmission, reciever box, and single motor mount plate. I also ended up getting
some new tires.
After putting the new tires on, one of the center driveshafts melted and snapped after about
I went ahead and placed a large order of FLM parts, here is what I ordered:
FLM Extended Chassis
FLM Front / Rear Bulks
FLM Bulkhead Braces
FLM Front / Center / Rear Skids
I can't wait to get my package.
I'ts still a good thing you changed the tires, the stock ones have a large gap and that gives it a wobble on harder surfaces.
