MOTORS AND GEARING
YourDouble-X'CR'carincludes an 84 tooth, 48 pitch spur gear. The overallinternal gearboxratio is2.19:1. The externalpinion
gear
will determineyourgearratio.
To figure out thefinal driveratiofirst divide the spur gear size by the pinion gear size. Say you
areusinga20tooth piniongear, you woulddivide 84 (spurgearsize) by 20 (piniongearsize). Forexample: 4.2 is yourexternal drive
ratio. Nowmultiplythe internal
drive ratio (2.19) by the externaldriveratio (4.2). Forexample:Thistells you that using a 20 tooth
pinionanda 84tooth
spur gear, the final driveratiois9.198: 1.

Step 14. Attach
the steering brace wi th two 4-40 x 3/8"
cap head screws (6)
through steering brace (39) and into
chassis (11).
e IMPORTANT NOTE: Tighten the two 4-40screws all
the wayandthen back them off 1/8 of a turn .Thiswill keep the
postson the chassisfrom "taking a set• if they shouldtwist at
all.
fillf you shouldeverneed to remove the small bushings,
the easiest way to get them out is to slightly thread a 4-40
screwintothemandpull them out.

*Note: If you do not have your servo at this time, skip to
BagC
and continueassembly. It is recommendedthattheservo
be installed at this time since much of the front end is built
around the servo and minor disassembly will be required to
install it later.
e IMPORTANTNOTE: lfthe servomountinginstructions
arenotfollowedcarefully,
your servo may be damaged!
Step 16. Using a file or a Dremel tool, trim the two lower
ears off of your servo(notincluded) as shown in figure 16. Be
very careful
to trim the correct ears! If the wrong ears are
trimmed,
your servo will not be able to be mounted unless
the servo case
is replaced.
e IMPORTANT NOTE: It is not recommended that you
usecutters or a hobby knife to remove the servo ears. Some
cases are made of very brittle material and damage to your
servo case may result.
