Team Losi has supplied all necessary Allen wrenches and a special wrench that is needed for assembly and adjustments. The following
common tools will also be required: Needle nose pliers, regular pliers, hobby knife, scissors or other body cutting/trimming tools, and a
soldering iron may be necessary for radio installation. 3/16", 1/4", 11/32", and 3/8" nut drivers are optional.
A suggested radio layout is provided in this manual. Your high performance R/C center should be consulted regarding specific questions
pertaining to radio/electrical equipment.
When in question, use the hardware identification guide in each step. For screws, the prefix number designates the screw size and number of
threads per inch (i.e., 4-40 is #4 screw with 40 threads per inch). The second number or fraction designates the length of the screw. For Cap
Head and Button Head Screws, this number refers to the length of the threaded portion of the screw. For Flat Head Screws, this number refers
to the overall length of the screw. Bearings and bushings are referenced by the inside diameter x outside diameter. Shafts and pins are referred
to by diameter x length. Washers are described by inside diameter or the screw size that will pass through the inside diameter. E-clips are sized
by the shaft diameter that they attach to.
The XXX-T MF2 includes an 86-tooth, 48-pitch Kevlar spur gear. The overall internal drive ratio of the transmission is 2.56:1. The pinion gear
that is used will determine the final drive ratio. To calculate the final drive ratio, first divide the spur gear size by the pinion gear size. For
example, if you are using a 18-tooth pinion gear, you would divide 86 (spur gear size) by 18 (pinion gear size) 86/18=4.78. This tells you that
4.78 is the external drive ratio. Next, multiply the internal drive ratio (2.56) by the external drive ratio (in this case 4.78). 2.56 x 4.78 = 12.23.
This means that by using a 18-tooth pinion gear with a 86-tooth spur gear, the final drive ratio is 12.23:1.
Consult your high-performance shop for recommendations to suit your racing style and class. The chart below lists some of the more
common motor types and a recommended initial gearing for that motor. Ratios can be adjusted depending on various track layouts, tire sizes,
and battery types.
