:: Tuning Tips (cont.)
Rear Hub Spacing:
You have 3 options for rear hub spacing, FORWARD, MIDDLE, & BACK. The kit setting is FORWARD, which provides
the most rear traction and will be used most often. For improved handling in bumps or rhythm sections, try moving the
hubs to MIDDLE or BACK. This can also make the car handle better in 180 turns.
Rear Anti-Roll Bar:
The #9780 B44 anti-roll bar kit (A.K.A. swaybar) allows you to add roll resistance to the rear end with minimal effect on
handling over bumps and jumps. The anit-roll bar is very helpful when trying to tune the suspension. The black bar is the
softest (.047” wire) and the silver (.055” wire) is the standard. It is popular to run a rear anti-roll bar in 4wd to help the
car square up more out of turns.
Rear Arm Hole:
The inner hole in the arm tends to work the best over the bumps and jump sections. Changing to the outer hole in the
rear arm will tend to make the rear end feel more “locked in” and less responsive. Making this change to the outer hole
requires you to remove the downtravel limiters from the rear shocks.
Setup Sheets:
Most often, the best way to get your car handling right is to go to our website www.rc10.com and click on the links
to Setup Sheets, then RC10B44.2 setups. Our team of professional drivers help develop these setups at National
events. Also, most drivers have a “base” setup that they use as a starting point for every event. Try running some of our
base setups OR look for track conditions and tires that are similar to your local track and mimic that setup. Remember,
each adjustment has a purpose, so copy everything from the setup sheet and then make adjustments based on the
recommendations in this manual.
Battery Placement:
The B44.2 battery cradle allows for quick battery spacing adjustment to fine tune the front to back weight distribution
as needed. A simple rule of thumb to follow is, if your car pushes through the corner, shift the battery back & if it
oversteers in the corner, move the battery forward.
Ackerman:
“Ackerman” refers to the relative angle difference between the front wheels as they are turned to steer the car.
More ackerman means that there is a greater difference in angle between the wheels, and the less ackerman you have
the closer the wheels steer parallel to each other. The ackerman on the B44.2 can be adjusted by moving the steering
rack ballstud forwards or back on the steering rack.
The steering ballstud in the back position on the rack (More Ackerman) will make the car more forgiving to drive,
particularly in looser conditions.
The steering ballstud in the forward position on the rack (Less Ackerman) will make the car twitchier around center but
will have more steering mid to corner exit.
Rear Ride Height:
The rear ride height setting you should use most often is 20 mm (the rear arms appear level when looking from the
rear). Check the ride height by lifting up the entire car about 8-12 inches off the bench and drop it. After the suspension
“settles” into place, raise or lower the shock collars as necessary until there is 20 mm gap from the bottom of the
chassis to the ground. Note: Check the ride height gap at the rear end of the carbon fiber chassis, not at the rear
chassis plate which is raised for more ground clearance. The chassis should look level from the side.
