How to Install TRI-UNITY30 on the Axial SCX30 CJ-7 (Keep Your Stock SLT2 Transmitter)
Posted by: Furitek -

Turn your Axial SCX30 Jeep CJ-7 into a brushless crawler and keep your stock Spektrum SLT2 transmitter. In this video we install the Furitek TRI-UNITY30 FULLRANGE DRIVE, which combines a brushless motor, a geared transmission and an FOC ESC in one compact unit. The result is ultra-slow, smooth crawling and a much higher top speed: up to 4X stock with the SPEED version, and up to 3X stock with the TORQUE version.

What you need

  • TRI-UNITY30, TORQUE or SPEED version (see the parts list below)
  • Furitek aluminum skid plate: required, because the stock SCX30 skid does not fit. Buy it separately, or get a TRI-UNITY30 "with Alu Skid" version.
  • Micro SLT2 Receiver, so you can keep using your stock Axial SLT2 transmitter
  • Tools: 1.3 mm hex driver, and a hobby knife or rotary tool

Step by step

  1. Remove the body and the stock drivetrain (0:40).
  2. Install TRI-UNITY30 and the aluminum skid (0:54). Trim the center plastic as shown in the video so the unit sits correctly.
  3. Plug in the Micro SLT2 receiver (1:08).
  4. Bind it to your stock transmitter (1:22). Binding is a one-time step.
  5. Test everything before the body goes back on (1:38): check steering and throttle direction.
  6. Trim the body if needed, then reinstall it (1:50 and 2:01).

Then watch the crawl and speed test at 2:24.

Parts used in this video

TORQUE or SPEED? Choose TORQUE if you mostly crawl and want maximum low-speed control. Choose SPEED if you want more wheel speed for trail driving.
