RC Beginner Series – Adjusting Camber and Toe

Team Associated
With modern day hobby grade RC’s, there are so many adjustments that can be made to effect the handling and performance of the vehicle. Adjusting Camber and Toe are important adjustments to effect how your RC performs on the straights and the turns.

What is Camber?

Camber angle is the measure in degrees of the difference between the wheels vertical alignment perpendicular to the surface.  Most vehicles will have a perfect or zero degree camber.  Most off road vehicles will benefit from a negative camber degree resulting in a slightly wider width on the track surface which will benefit in the turns and reduce roll-overs.

Adjusting Camber?

Adjusting Camber is an easy process on most RC’s and is very easy to complete in just a few steps.  You’ll need a couple of items to make the process go easy:

You’ll want your RC in a full ready to run state, including the battery and body. (My photos show body off for better viewing)

1. Drop your vehicle from about one foot onto your hard flat work surface, setting the RC into it’s suspension.

2. Check the camber degree by moving the gauge toward the tire making sure you have contact with the bottom and top of the tire with the gauge.

3. Determine which way you need to dial the turnbuckle to obtain your desired camber degree.  Typically moving the wrench toward the front of the vehicle will lengthen the camber turnbuckle adding positive camber and turning toward the rear of the vehicle will shorten the turnbuckle adding negative camber.

4. Repeat steps 1-3 until you get the perfect degree for your vehicle.

5. Check your camber degree before each run and if you damage your RC.

Pro-Tip:  Rotate the tire 180 degrees and check the opposite side just incase you have a bent wheel or bent stub axle.

What is Toe?

Toe represents the angle derived from pointing the tires inward or outward from a top-down view – and in this case the front steering tires.  Most RC vehicles benefit with a perfect parallel position of both front tires causing the least amount of friction on the track.  Some off road vehicles can benefit from a Toe-out angle to have a bit more aggressive steering allowing the inside tire to turn quicker into the turn.

Adjusting Toe

Adjusting Toe is an easy process on most RC’s and is very easy to complete in just a few steps.  You’ll need a couple of items to make the process go easy:  A hard and flat work surface and a turnbuckle wrench that fits your RC.  You’ll want your RC in a full ready to run state, including the battery and body. (My photos show body off for better viewing) There’s not a gauge or caliper to really measure the toe angle.  You can take measurements with a tape measure on the front and rear of the tires though.  You will want both steering turnbuckles to be the exact size and adjust both turnbuckles in equal amounts.

1. Drop your vehicle from about one foot onto your hard flat work surface, setting the RC into it’s suspension.

2.  Turn each steering turnbuckle in equal amounts to the desired toe angle.  Typically moving the wrench toward the front of the vehicle will lengthen the turnbuckle adding toe-in and moving the turnbuckle wrench toward the rear of the vehicle will shorten it adding toe-out.

3. Repeat steps 1 and 2 until you reach the desired toe angle.

How did your RC do with the Camber and Toe check?  Did you see better results while driving once you adjust those items?
