and I have a few questions.

Could the motor be cogging?

This is from Castlecreations. The ones who make the mamba systems.

5. My vehicle acts like it has "turbo lag" (poor acceleration/punch for the first few feet or yards, and then it "kicks in").
Make sure you're using high quality batteries, and a battery connector capable of high amp flow (75A minimum!)…we recommend our 6.5mm CC Bullets, Deans Ultra connectors, or the Traxxas TRX connectors. This behavior is very typical of a battery pack that is having difficulty providing the power your vehicle/system requires for top performance. The faster the top speed of the system, and the more traction available, the harder the batteries have to work to accelerate the car.

It means the motor isn't getting enough energy to initiate movement. You'll have to squeeze your trigger harder. Also, try updating your firmware to the latest and greatest. Mine has the newest stuff, and it works MUCH BETTER. It's allot smoother, and the brakes are easier to deal with.

just set the gear mesh so there is a tiny bit of play between the gears.


that is a 1.0 btw too. Just saying so someone else doesnt correct you at the track or something.

When I disassembled everything, it all looks okay and the bearings are all smooth. I think the gear mesh is just very, very tight. Is this normal? Does the rear gear box need to break in more? I have between 1 and 1.5 hours of run time on the car, and the rear gear box has not improved. Does it just need more time, or is this something unusual?

My car is a 1.0, so you can not shim the rear diff. Would it be worth it to upgrade to the 2.0 rear gear box set so I can shim my gear mesh? Any help would be appreciated. I'm new this shaft drive thing. All my TC's are belt drive so I've never had to deal with bevel gear mesh before. Thanks!

You can shim the 1.0 diff.....Not as much as the 2.0...but all you have to do is use 8x10 or 8x12 basically any 8mm shim and stick it Under the Flanged bearing...obviously you want to make the mesh a little looser...so install it under the Ring Gear side of the cup and when installing the diff you might need to give it a little force.....its nothing drastic...you will hear/feel the diff "click" into place..and the mesh should be Golden....I did this on Both my 1.0 B and T for the fact i Did Not like the whole "diff breakin" I shim them Smooth right outta the box and have NEVER had a R+P fail.

thickest shim you can use is a .3 you will prolly need .1 or .2

Kyosho makes a nice 8mm shim kit.

Dont forget about the coupons as well...saving a buck or 2 where you can helps.

$75.00 - 149.99 = $5.00 RCMAR95
$150.00 - 249.99 = $12.50 RCMAR912
$250.00 - 799.99 = $25.00 RCMAR925
$800.00 + = $75.00 RCMAR975

Ran my 8ight E 1.0 Sunday with the heavier oils.
Still dialed and less chassis slappin the ground.
Feels like it's easier to drive fast thru the big jumps.

I'm running 3/5/2 in my truggy. It handles awesome, but when I hit the breaks at high speed, it almost flips forward, the rear tires come OFF THE GROUND and they actually turn, BACKWARDS! I may have to add a throttle servo back in, just to minimize that issue. I just rebuilt the rear diff a few weeks ago, and it already has a click.
