Awesomatix A12 Gearing Considerations for Stock 17.5 and GT12 21.5 Racing

The innovative Awesomatix A12 platform, with the inline design and inner and outer chassis frames, introduces some new constraints to traditional 1/12th scale racers -- gear selection.  The A12 has already proven itself in both Super Stock 13.5 and Modified 1/12th scale racing, but until recently it hasn't been even tested with slower / higher wind motor combos.  

Just like many of you, we race 1/12th scale too, so we know that people will be surprised about the need for different sized spur gears.  So read up and learn about our new 1/12th platform!!

Design Considerations

The “No tweak pod” concept offers a smaller range of motor fore and aft adjustment than we traditionally find within a 1/12th scale car.  The pod offers two axle positions, and these positions offer different quantities of "gear count".  Between the prototype A12 and the production A12 the amount of gear choices has been greatly increased.  

All of the following calculations are based upon a 36mm diameter 540 motor.  Motors with a smaller diameter, like the Team Scream Low Rider series can support even a wider range of gears.
  • Short wheelbase: 112T to 120T of gear count
  • Long wheelbase: 112T to 125T of gear count (aka, +5 teeth)

What is Gear Count?

Simply put - the sum of 64 pitch spur + pinion teeth should be in the range of

  • 112 to 120 for short wheelbase
  • 112 to 125 for long wheelbase

Simple Gear Charts

The following is a simple roll-out calculation based upon a 40.0mm rear tire size.  This tire size is often a great starting point for spec racing, but is by no means the smallest tire that can be run on the platform.  

Our roll-out targets for motors were:
  • 17.5 - 95mm
  • 21.5 - 102mm
The areas shared in the salmon color signify gear that is supported when running a long rear wheelbase in the A12.

We decided to make a small run of 63mm spur gears for one reason only.  It would allow the gearing math to IDENTICALLY match the 72/56 gearing that is recommended in Can-Am RC Series 1/12th Stock.  Running a 63/49 is identical to 72/56.

We just did all of the hard work for you.... Thanks us with an order!

Awesomatix A12 1/12th Scale Electronic On-Road Car

Awesomatix, known for their advanced and revolutionary design of 10 th scale RC electric touring cars, is excited to enter a new class, 12 th scale RC electric on-road, with the A12 pan car.  

A low center of gravity is a critical element in racing performance for any class, and this is further exemplified by the A12 pan car on an entirely new level. Much like the Awesomatix A800MMX touring car, the A12 far surpasses all existing 12 th scales by providing a much lower center of gravity.

A 12th Scale the Awesomatix Way

The Awesomatix A12 features a completely new design compared to any previous 12th scale car on the market.  The A12 does not have a standard lower deck / chassis and lower pod plate, but rather is composed of two parts that work in tandem and are connected with ball joints. The outer frame of these two suspension components contributes to the spring action of the car as it functions like a large spring.  The inner frame contains the front end, servo, receiver, esc and battery.  A hydraulic damper is built between these two parts of the frame, providing easily adjustable dampening and rear axle movement. The end result is a suspension and pivot movement that is similar to conventional 12th scale cars but has proven to be far more durable and tweak free.
Additionally, the alloy side braces on the outer spring frame offer several possibilities to play with rate of the “rear suspension” by simply moving and adjusting a set screw. The stiffness of the chassis can be adjusted very quickly for a variety of track conditions.
The A12 follows the Awesomatix tradition of innovation by using specially designed hydraulic rotary dampeners instead of traditional oil piston shocks.  The A12 rear rotary damper unit is very compact in size and mounted at the lowest possible point on the chassis. Inside of the damper case are two rotary damper “vanes” that work independently to ensure smooth and efficient dampening, which can be adjusted by different viscosity silicon oil. This carefully designed damper provides the required ratio between both the longitudinal and side dampening needed to excel on any track condition. This rear damper is easily removable, too, as just two screws allow for the “quick release” of the entire unit. 

Front End Design

The 7075 T6 aluminum front hubs on the A12 have created a highly adjustable front end design. This kingpin design enables the use of different viscosity oil, grease, and o-rings within the front hubs along with traditional coil-over springs to ensure optimal performance on any racing surface.
Setting the front end camber is quite simple and is done by turning the kingpin post. Predetermined holes in the front carbon suspension plate line up with predrilled holes in the kingpin post which together determine camber angle.  This allows camber to be changed in 0.25 degree increments, from 0.75 to 1.75 degrees.
The A12s stiff front bumper design matches the shape of the front carbon suspension plate and is cut at an angle to match the front-end shape of most commonly used body shells. Unlike most 12th scale kit bumpers, no hand fitment is required and the bumper’s stiffness helps prevent damage in the case of a crash.   

The Inner Frame 

The design concept of the car supports an inline battery and centralized electronics placement. The servo is mounted to the front end cross plate. Multiple sizes and shapes of servos can be used, up until a maximum dimension of 35mm x 30mm x 15mm.  The ESC, receiver, servo and transponder are located in front of the battery.  The rear rotary dampener is positioned under the battery at the back of the Inner Frame. The inner frame connects to the outer frame with 2 ball joints at the front end that allow it to pivot, and small hooks on each side of the damper vane connect it to the rear pod assembly to provide the ideal dampening level.

The carbon side wings offer two possibilities for both side spring placement and rear body posts position.  The side spring positions offered on the car allow for variable side roll stiffness depending on the conditions.  Depending on the body shell used and its mounting position, the narrow or wider holes may be more suitable to ensure no deformation of the body shell at high speeds. 

Rear end design

Another Awesomatix innovation is an ultra-lightweight spring steel-alloy composite spool axle which uses a center nut to quickly change the spur gear. The total weight of this fully-metal spool unit is less than the most competitors’ carbon spools but with far greater total strength and torsional rigidity. 
The very light, solid circular aluminum rear beam provides exceptional rigidity and a tweak-free operation for the rear pod. This rear beam can be set in a short or long wheelbase position, and shims used under this beam set the desired ride height.

Currency Markets Drive October 1st 2020 AwesomatixUSA Price Increases

The USD dollar has devalued by about 11% as compared to the Euro over the last 9 months (Euro-Dollar moved from 1.11 to 1.19 in the last 3 months).  The weakness in USD vs Euro is forcing a price change for AwesomatixUSA as we must pay Awesomatix in Euro.

Price change going into effect on October 1 2020 for all Awesomatix Car Kits and Parts.  Since we haven't performed a site wide repricing since 2017 certain parts will fluctuate in price up or down by 4 USD.  The most impactful changes will be the price increases to the newest car kits:

  • A800MMX and A800MMX increase from 689.00 USD to 756.50 USD (+67.50 USD)
  • A12 increase from 375.00 USD to 397.00 USD (+22.00 USD)

With the upcoming price change, there is no better time than now to pick up a new A800MMX or A12 series kit.  Kit back orders will be accepted at the current low prices until the October 1st price change...
