Experimentation.
You want to gear your motor so you are getting to top speed around 3/4 way down the straight, but still have good punch out of corners.
All the while keeping temperatures of the motor after a 6min run around 60-80deg.C
Different motors or the same turn rating have different RPM and torque characteristics. And then playing with end bell timing will alter this as well (higher timing means more RPM - but more heat typically)
Common range for a modern 13.5 motor is 3.8-4.8 and circa 50deg total timing (be aware not all motors are at zero when showing zero on the can - R1 is like this for example, 30deg on the can is more like 60deg absolute)

The motor mount is different and there were more mounting options for the ARS system. The 2016 kit also came with ECS shafts in the kit. Other then that its all the same.

1. chassis of 16 has more motor mount holes as the motor mount plate in the 16 is longer to accommodate 2 more holes.
2. the 16 kit comes with ECS front driveshafts, none in the 15
3. top deck of the 16 has more space around the motor for easy access to the pinion gear
4. the rear blocks of the 16 has holes for ARS roll center adjustment
That's it I think...

Setup sheet
Hello, just a few questions about the setup sheet format. I was wondering what the roll center area between the eccentric inserts at the bottom of the page on the left was about. Also, for the wheelbase area on the top, are the squares to be filled out representing the general position of the arms (forward middle or back) or are they the size of spacers used in front (which would have the opposite wheelbase effect). Thx for clarifying.

You can use .5mm or 1mm inserts to change the roll centers in the direction indicated.
The wheelbase checkboxes indicate how many shims are in front of each arm. So stock settings would have a single (1) checked for both front and back. If you wanted to move the arms back, you'd have both of the 1 boxes checked. All the way forward would have just the 0 checked.

Does anyone make a 2mm graphite chassis for the car?
