ET48

What Motor should I purchase for my ET48?

There are a few options that we have tried in our ET48s combined with the Tekin RX8 GEN2 ESC. We prefer the Buggy motors over the Truggy motors because they are smoother on the low end because they do not produce as much torque as the longer Truggy motors, which can be a detriment. This means less wheel spin and a power band that is easier to control. We have done extensive testing with:

  • Tekin 1900 Buggy motor geared with a 15 tooth pinion.
  • Tekin 2050 Buggy motor geared with a 14 tooth pinion.
  • Tekin 2000 Truggy motor geared with a 15 tooth pinion.

I’m interested in your Slash 2WD axle upgrade kit but I really like my aluminum carriers. Do I have to run your plastic pieces or can I keep my aluminum ones?

For our Slash 2WD kit you will have to run our plastic carriers. There are currently no aluminum carriers that will fit our axles. Because we increased the diameter of the stub axle and captured the CVA we needed to uses larger bearings that simply will not fit in any other carrier. We designed the carriers to be super beefy and they have proven to be nearly indestructible. We designed them to be tunable, allowing for multiple roll center options with the camber link as well as the outer hinge pin. Our thoughts were that if plastic is good enough for 8th scale off-road, it can handle duties in a Slash.

I’m interested in your Slash 4WD axle upgrade kits but I really like my aluminum carriers and steering blocks. Do I have to run your plastic pieces or can I keep my aluminum ones?

For our rear axle kit you will have to run our plastic carriers. There are currently no aluminum carriers that will fit our axles. Because we increased the diameter of the stub axle and captured the CVA we needed to uses larger bearings that simply will not fit in any other carrier. We designed the carriers to be super strong and they have proven to be nearly indestructible. We designed them to be tunable, allowing for multiple roll center options with the camber link as well as the outer hinge pin. Our thoughts were that if plastic is good enough for 8th scale off-road, it can handle duties in a Slash. For our front axle kit you do have some options if you wish to run aluminum steering blocks. If you’re currently running aluminum what you’ll need to do is purchase a 6×11 bearing and use it in place of our 6x12mm bearing. The other option you have is to use the steering blocks from the Traxxas X-01. They are a direct replacement for ours. They fit our bearings and axles without any mods.

Do you sell an M6 driveshaft kit that is compatible with the Electric Rustler/Stampede?

At this time we don’t have a kit solely for the 2WD Electric Rustler/Stampede, But you can purchase these parts below and make the 2WD Slash nitro Rustler/Stampede kit work for the electric counterpart. You will need TKR1951X and TKR2210 for the Electric Rustler/Stampede. The TKR2210 replaces the CVD’s in the 1951X kit to make the kit fit on the electric Rustler/Stampede. The 2210 CVD is a little longer than the 1951X CVD which is needed to fit the electric Rustler/Stampede.

Do you offer M6 axles for the Slash 2WD with ProTrac arms?

At this time we don’t have a kit solely for the 2WD Electric Slash with Protrac arms, But you can purchase these parts below and make the 2WD Slash kit work for the Protrac equipped counterpart. You will need TKR1951X and TKR2210 for the Electric 2wd slash with Protrac arms. The TKR2210 replaces the CVD’s in the 1951X kit to make the kit fit on the Protrac equipped 2wd Slash. The 2210 CVD is a little longer than the 1951X CVD which is needed to fit the Protrac's longer arms for 2wd electric Slash.

I’m interested in your Stampede 4WD axle upgrade kits but I really like my aluminum carriers and steering blocks. Do I have to run your plastic pieces or can I keep my aluminum ones?

For our rear axle kit you will have to run our plastic carriers. There are currently no aluminum carriers that will fit our axles.

V4 Conversion Kits

What bodies fit the V4 conversion kits?

The most popular body for the V4 chassis’ would be the Losi eight 2.0 E body. With Velcro on the mud guards and on the body we have had great success with that body. It requires minimal trimming to fit any of the V4 conversions and still allows the use of body clips as well as Velcro if desired. The Losi part number is LOSA8097. Another choice is the FTW. They produce a couple of bodies for our V4 chassis’ including the Mugen MBX6, Hotbodies D8 and Losi 8E 2.0.

What rear chassis brace is needed for all V4 Truggy kits (except Losi)?

What motors fit in the V4 42mm motor mount provided with the kit?
