Steering angle of the Transmitter
 

Hi Rc-Racers,

this may be an odd question, but i would like to know, which max steering angle do the usual Radios have?
My Sanwa MX-V has maybe 45 degree range of motion from center to left(or right) or even less.
In my opinion a bigger range would be more precise/accurate!

What do you think? Which range of motion has your Transmitter?

More travel = less speed.....

I don't usually turn my steering full lock to lock even in my tiny track I have in the basement so not sure. I run a 4PKS-R.

Might want to adjust your servo horn size too if the range is not enough for your steering needs and use some expo to compensate. Also use a fast and torquey steering digital servo.

With a wheel that turns farther you are going to have to turn the wheel farther to get the same throw. It takes time to transition the wheel back and forth. Think like in a 1:1 f1 car. they have really fast racks. With a slower rack you would be more precise, but not as quick as it takes a long time to transition the wheel.

If you want to be more precise through the travel of the wheel lower the dual rate. This lowers your max throw, but raises your input output ratio of the wheel to the wheels of the car. So for example it may be 1:1 but with reduced dual rate it may be 1: .75. This is usually fine as you never use full throw in most situations. Most high end radios have options to lower your throw anyways.

Messing around with expo is ok, but also has reprocussions at high levels of steering throw making the car react much faster than at lower throw. Adding expo should be a action done sparingly.

I agree with all explanations of the posts so far, but i think there is some potential there...
In my opinion, the maximum moving speed of my hand/arm rotation is far higher than what i need on the track with the given ratio of steering angle of the car vs. transmitter wheel angle. Just watch even the pro drivers, they dont use soooo fast turning on the transmitter.
So i conclude, that given a smaller ratio of steering angle of the car vs. transmitter wheel angle and the same max car steering angle by having more "throw"/max angle on the transmitter could (maybe) lead to a better drivability even for lets say experienced driver...

The is an app for my smartphone (smart protractor or something). If i hold my phone like a transmitter steering wheel, and rotate it to the max comfortable angle, i get results as follows:
left angle (from center) : about 50 degree
and roughly the same to the right
So the whole arm rotation (transmitter steering angle) i feel comfortable with is about 90-100 degree. Typical transmitters maybe get to the half of that value.

I didnt had the chance till now to grab a good transmitter like m12 for example, but i simply would like to know the rough value of center to left max angle or whole angle.
And the last Question, is there a Radio, where you can adjust that? Propably no...

sorry for the english, it isn´t my mother language... (german)
sorry, too for the long post
Greets, Phil

my radiopost has 60 degress. so 30 each side..

My ko propo radios have the adjustments on the radios menus to do so and also the radios wheel has a adjustment 2 screws you screw in or out so you can make the wheels throw lock to lock left and right less or more.

This is why I love ko propo radios they do almost anything.

WOW thanks for that post, thats what i was looking for.
@reptile: Which exact radio do you have?

Hi I have these 2 EX1 UR and helios and the newer one bellow also and they all have the adjustable steering wheel throw.
