:: Introduction

Thank you for purchasing this Team Associated product. This assembly manual contains instructions and tips for building and maintaining your new RC10TC7.2.
Please take a moment to read through this manual to help familiarize yourself with these steps. We are continually changing and improving our designs; therefore,
actual parts may appear slightly different than in the illustrations. New parts will be noted on supplementary sheets located in the appropriate parts bags.
Check each bag for these sheets before you start to build.

:: KIT Features

With the current touring car platforms reaching an even higher plateau of precision and performance, the Engineers behind the doors of Area-51 wasted no time
in ensuring the TC7.2 is up to the level. The RC10TC7.2-FT comes packed full of a host of new components and features necessary to keep you on top.

As the on-road market advances at an ever increasing rate, more is demanded from the chassis’ to accommodate the ultra-competitive racing classes. A successor
to the TC7.1, the TC7.2 maintains the proven suspension geometry, but adds the refinement to chassis balance and flex necessary for today’s racing class. The
centrally mounted IFM motor mount adds several mounting configurations to help fine tune chassis flex to the racing surface, and also has an integral mounting
position for an optional chassis pitch control system (PCS). The TC7.2 also carries an all new aluminum rear gear differential for the ultimate in precision and heat
dissipation, as well as an ultra-light front spool assembly. Along with a list of new features, the RC10TC7.2 FT gives you everything you need to keep you racing
at the highest level. All without sacrificing low part count or affordability. A well-refined racing chassis with success in its heritage, the RC10TC7.2 FT is another
“Champion by Design” from Team Associated!

• Battery charger (suited for, and particular to, one of the batteries mentioned) • Body Scissors (AE Part #1737)

• 2 channel surface transmitter, 2 channel receiver, and steering servo • 1:10th scale rubber (or foam) touring car tires, wheels and inserts

• Silicone Shock Fluid (Refer to catalog for complete listings) • CA Glue (AE Part# 1597)

• Silicone Diff Fluid (Refer to catalog for complete listings) • Thread Lock (AE Part #1596)

• Shock Shaft Pliers (AE Part #1675) • FT Dual Turnbuckle Wrench (AE#1114)

o A narrow 84mm wide to minimize chassis dragging at maximum chassis
roll angles
o Chassis incorporates mounting position for 1UP DTC
(Dynamic Toe Control) rear end option
o Chassis ballast mass mounting locations to fine tune mass balance

• PCS (Pitch Control System) option to further adjust chassis flex characteristics
o Motor mount and servo mount incorporate mounting positions for pitch
control brace option

• Fox “short” shocks with genuine Kashima Coating
o “Short” shock lowers overall center of mass allowing for more stability in
high grip conditions
o Ultra-smooth Kashima Hard Coating for minimal friction and extended
wear
o Hard coated shock shafts with polished finish
o Machined piston and bushing sets for the most precise build
o Updated bladder profile for consistent performance

• DCV drive shaft assemblies included for front drive
o DCV (dual CV) drive shafts are double-cardon joints, allowing free rotation
of drive shaft at extreme angles typical of the front drive due to addition of
steering angle to suspension arm angle
o The use of DCV’s results in smooth steering through larger corners by
eliminating the “chatter” typical of standard CV axles

• Ultra-light weight carbon composite suspension components
o Carbon composite material used for the best combination of strength at
minimized mass
o Optimized suspension arm length and shock mounting positions
o Pivot ball on inner hinge pin allows free pin movement at any toe or kickup
angle
o Insert system for precise adjustment of toe and inner pin width
o Independent arm mount design to allow maximum flex through entire
chassis length, resulting in better grip on all track conditions

• Aluminum rear CV bones
o 7075-T6 aluminum with hard coating for ultimate durability and decreased
wear
o Low rotational mass

• 26 precision ball bearings

With the shaft extended 25%, place bladder on
the top of the shock body, displacing the extra oil.
While maintaining pressure on the bladder against
the shock body, carefully lift one side of the bladder
to allow any extra oil to escape. Place stock cap on
top of bladder, and secure it by threading the
aluminum cap retainer onto the shock body.

Droop:

The standard settings of 6mm front and
5mm rear will work best in most cases.
Droop is measured just underneath the
outer hinge pin as shown in the photos
to the right.

On bumpy or low grip
surfaces, increase the droop (going to a
lower number on the droop gauge), this
will help increase traction and consistency.

Droop adjustments of 0.5mm to 1mm can
be very effective on the track!
