2. BAG A ....................1-7 3. BAG B ....................8-11 Team Losi is continually changing and improving designs; therefore, the actual part may appear slightly different than the illustrated part. Illustrations of parts and assemblies may be slightly distorted to enhance pertinent details.
BAG A STOP! There are two, complete differential assemblies in the XXX-4 kit. The Front - plastic differential, shown in steps A-1 thru A-9 and The Rear - steel differential , shown in steps A-10 thru A-19. The XXX-4 kit was designed using the stock 42T drive pulleys in the front and rear of the car.

4. The tires should now be glued to the wheels. This can be done by using a fast-curing superglue or cyanoacrylate glue available at your local hobby shop. Allow the glue to dry thoroughly before continuing. Team Losi Tread Lock Tire Glue (A-7880 "Thick", A-7881 "Thin") is the best glue available for gluing R/C car tires.
BAG H Step H-1 Front Bumper Install Figure 69 1. Holding the car upside-down install the front bumper (59) by lining up the holes in the fork of the front bumper with the holes in the chassis (46). It should rest on the front diff cover (62). Secure the front bumper by threading two 4-40 x 1/4"...

Align the holes in the motor mount with the holes in the motor as indicated in Figure 71.
Page 35
BAG H (Continued) Step H-5 Battery Strap Install The battery strap can be mounted in one of two ways to accommodate different styles of batteries. If you will be running matched-type cells, or individual cells laid out side-by-side, the TL logo should be facing away from the top of the chassis as shown in Figure 73 "B".
BAG H (Continued) Step H-7 Gear Cover Installation Figure 75B Figure 75A 1. Locate the gear cover (191) and cut the bottom side of it along the trim line as shown in gray in Figure 75B. Drill three 1/8" mounting holes in the gear cover at the three locations marked with dimples.
BAG H (Continued) Step H-9 Wing Installation 1. Make two 3/16" diameter holes in the wing (192) where the dimples are located. 2. Align the holes in the rear wing with the wing mounts on the rear shock tower. 3. Secure the wing to the wing mounts by first placing a wing washer (67) over the mount ontop of the wing and then inserting a body clip (124) in each hole.
This also reflects on the "balance" we referred to earlier. Never make more than one change at a time. If the change you made works adversely or doesn't address your need return to the stock position and try something else. Team Losi's development team has put hundreds of hours on the XXX-4 to arrive at the set-up we put in the instruction manual.
Page 39
Front End: Shock Location: Leaning the shocks in (mounting them closer to the center of the tower) will give a smoother transition as you enter into turns and improve consistency but will yield less total steering and give a slower reaction. This might be helpful on high bite surfaces.

We are sure that you will find the XXX-4 Buggy to be the most versatile and easiest car to drive fast with great consistency. We at Team Losi hope this information helps you to enjoy your XXX-4 Buggy and racing as much as we do.
