Tow Hitch Receiver for Rlaarlo JK07

What This Is

Rlaarlo hit it out of the park with the JK07. It’s brilliant. However, one thing it can’t do is tow a trailer. That ends today!

This is an easy print that will solve your towing problem, though you will still need the actual tow hitch itself.

Tow Hitch Receiver for TK07

How to Print

I printed in PLA+, though PLA, PETG and other rigid filaments should be fine. I’d suggest these settings:

  • I print with a 0.6mm nozzle, but most of you reading this will use a 0.4mm nozzle.
  • I printed at 0.24mm, but 0.2mm will be fine as well.
  • Suggest 4 or 5 wall thickness
  • 25% Cubic infill for all parts.
  • I used PLA+. PLA should work fine, as should PETG.

Installation

  1. Open the body so you can access the rear of the car. It doesn’t have to be unbolted.
  2. Attach the Receiver to the JK07 Hitch Bracket piece with the 3x CSS screws. Don’t over-tighten!
  3. Remove the 8mm screws from the rear of the inner fenders. You won’t need these again.
  4. Align the JK07 Hitch Bracket piece between the inner fender holes. Loosely attach with 2x 12mm BH screws.
  5. Insert the remaining 4x 12mm BH screws into the Hitch Clip pieces and firmly affix these over the rails to the JK07 Hitch Bracket piece.
  6. Once you’re happy with orientation, tighten the BH screws with the rear fenders. Should be snug.
  7. Slide the tow hitch or drop hitch bar into the Receiver piece and insert a screw or two. Done!

Wheel Wells for RGT Intruder EX86020

What This Is

Wheel wells for the RGT Intruder EX86020. This is a gorgeous vehicle and it deserves the best!

RGT Intruder EX86020 Wheel Wells

What’s Included

The zip file below contains:

  • A printable STL file for each wheel well (4 total)
  • Read Me.txt
RGT Intruder EX86020 Wheel Wells Top

How to Print

I printed in PLA+, though PLA, PETG and other rigid filaments should be fine. I’d suggest these settings:

– 0.4mm nozzle (or bigger)
– 0.24mm layer size (I used 0.3mm with my 0.6mm nozzle)
– 3 to 6 wall width (or wall or shell layers)
– 20% infill, cubic (10% minimum) – doesn’t really matter, it’s all walls
– Supports on base only, 30% angle. Only need to support the flat parts where the wells ‘wings’ need support.

RGT Intruder EX86020 Wheel Wells Bottom

Installation

  • Print per the above settings.

  • Hold the wheel wells over the chassis to see where the screws need to come out.

  • Do one corner at a time; remove the screws from the matching holes.

  • Move the top of the shock to fit (I stood mine up; good for a scale car)

  • Align the wheel well where it’s supposed go and use screws that are 4mm longer than the stock ones (I think you need 4x 18mm screws and 4x 14mm screws, plus 4x 12mm screws and locknuts to suit for the top of the rear shock hoops if you want to add them too. Not critical).

  • Repeat for the other corners. It’s pretty intuitive; these should be plug and play.

Servo Bracket for Cross RC UT4 Pro

Micro Servo Bracket for Cross RC UT4 Pro

What This Is

There’s a bracket on the Cross RC UT4 Pro that lets you have indepenent control of the front and rear diff locks with two servos, or to combine them and use just one servo for both.

However, a standard servo won’t fit, even with some cutting of the standard bracket. A micro servo won’t fit because it’s too small. The size that does fit is uncommon and you pretty much have to buy the Cross RC unit.

So, this bracket is one solution. to the problem. This bracket will allow you to fit a micro servo (like the Power HD TR4 or jxServo micro) to operate both diff locks at once, no cutting required. So much easier! Just be sure to use a strong servo!

  • Installing servo.jpg;
  • Print Orientation.jpg;
  • Read Me.txt

How to Print

I printed in PLA+, though PLA, PETG and other rigid filaments should be fine. I’d suggest these settings:

– 0.4mm nozzle (or bigger)
– 0.24mm layer size (I used 0.3mm with my 0.6mm nozzle)
– 3 to 6 wall width (or wall or shell layers)
– 20% infill, cubic (10% minimum)
– Supports on base only, 7% angle. Only need to support the flat parts where the servo ‘wings’ mate to the bracket.

Installation

  • Print per the above settings.

  • Install servo into the bracket.

  • Place into the UT4 diff lock servo area.

  • Ensure you use the two extra triangular plastic mounts Cross RC supplies with the kit.

  • This bracket is designed to screw into those as well as the other end of the mount plate.

  • Continue with setup per manual for a single servo to do both diff locks at once.

Installation

Place into the Intimidator’s tray and add your plates. You’ll want to put 1.25kg plates on for the first couple, so that they clear the sides of the ‘box’ the bracket sits in. Subsequent plates will clear the borders.

Long Motor Cross Brace for FMS FCX10

Long Motor Cross Brace for FMS FCX10

What This Is

This is a one-piece cross-brace that’s designed to replace the stock piece in the FMS FCX10 K5 Blazer. It sits between the motor and the servo and provides chassis rigidity and receiver holes for the shock hoop screws.

Print this tray and install it using the hardware that came with the car. You’ll have more room for your longer motor with no loss in rigidity or strength. Win-win!

What’s Included

The zip file below contains:

  • RC-TNT Cross Brace for FMS FCX10.stl
  • Read Me.txt
Cross Brace for FMS FCX10 Top-Down

How to Print

I printed in PLA+, though PLA, PETG and other rigid filaments should be fine. I’d suggest these settings:

– 0.4mm nozzle (or bigger)
– 0.24mm layer size (I used 0.3mm with my 0.6mm nozzle)
– 4 to 6 wall width (or wall or shell layers)
– 60% infill, cubic (25% minimum)
– No supports, brim or other helpers. Just print it flat and you’re done.

Cross Brace for FMS FCX10 Underside

Installation

Simply remove the stock cross-brace that sits between the motor and the servo in your FMS FCX10. Install this one, with the deeper gap at the back. There’s a small arrow on the top surface that points to the front of the chassis.

Now you have 6mm more room for a 560 sized motor, or for whatever other crazy thing you’re trying to run in the car.
