Changing toe in or toe out will affect how your rc car or truck corners.
Plus, it also affects your straight line driving ability.
Toe in or out refers to the horizontal angle of your tires. If leading edge of your rc tires are pointing in, when you look down at them from above, this is toe in.
If they happen to be pointing out this is toe out. Toe most generally affects both your turn-in ability on corners and straight line driving.
If you have the toe angle set properly straight line driving and cornering will be much easier. Learning how to set the toe angle on your rc car or truck will help you get the most out of your suspension.
You must have the toe set the same on both sides of your rc vehicle or your handling will be very unpredictable.
If you do have the toe angles set differently it can cause your car or truck to veer off unexpectedly, it will be difficult to get it to corner with any kind of rhythm, plus it will be impossible to drive it in a straight line.
So, understanding toe angles and how to set the toe angle on your car or truck is very important.
What toe in or toe out should your car or truck be set at?
On-road and off-road vehicles react differently to toe angle, plus track conditions also play a big part to what toe angle is the best.
Front toe in will generally result in increased stability on the straight aways, but it will increase drag.
Toe out on the front improves cornering ability, but can make your vehicle twitchy on the straights.
On the rear the only vehicles that use or consider toe-out are rock crawlers, this helps the crawler's rear end swing around corners and turns.
Rear toe in on all other vehicles helps to counteract over steer, improve off power steering and increase traction.
As a general rule of thumb, one to two degrees of toe in or toe out is all that you will want.
To adjust toe angle on the front of your car or truck will either be done by adjusting the turnbuckles or tie rod ends.
Adjusting rear toe angle is a little more complicated, because most all are fixed. With the rear being fixed it will require you change wheel hub carriers or bulk heads.
There are always a few exceptions, a few vehicles do use turnbuckles in the rear to adjust toe angle.
I am sure you are now wondering how do I check or measure the toe angle on my vehicle.
There are many different tools available to you to accomplish this task. Hudy and Team Integy both build setup stations for many different size vehicles that will make measuring and setting toe easy.
These setup stations and gauges can be expensive, so if you are on a tight budget there is away to build your own toe angle gauge.
To build your own toe angle gauge, you will need a piece of construction paper that is bigger than your rc truck or car. Plus you will need a ruler, pencil and protractor. I do hope that you remember a little from your Geometry class.
To start off place your rc truck or car on the construction paper, as straight as possible. Now you will need to draw a line that is perpendicular (right angle or 90°) to the leading edge of your paper along side your tires the length of the vehicle. Do this on both sides of your car or truck.
This may take practice and patience.
It is very important that these lines be both perpendicular to the leading edge of you paper and that they are parallel. Also, these lines need to be at the same distance to the tire. Now line up your protractor with a tire and read the angle relative to your straight line. That angle is your toe angle, either in or out. Now work you away around you car or truck checking each tire.
It is essential that you fronts and rears be at the same angle from side to side.
Once you have you toe angles set, this is one part of your vehicle's setup that crucial for better handling.
Once you master this way of checking and setting toe angle it will become easier, so you can check your toe on a regular basis.
Every once in a while check your toe angles to make sure nothing has been knocked out of whack or dent.
