I’m not a crawler guy but this information is very good and mostly applicable to buggies as well. One thing to note is the servo horn length: you can use a shorter one to increase the final steering torque and improve steering precision. Because the rotating horn projects an even smaller linear movement toward the ends of the throw, you have even more torque and less risk of burning up the servo when the steering knuckles get close to those hard stops. The downside to a shorter servo horn is reduced steering speed. If you were reducing the speed in the transmitter settings already, this is hardly a negative.
I’m happy that some people are seeing the crossover and I hope to expand outside crawlers where applicable. You make some great points. I actually made a SHORT on that topic but not sure that people can find both shorts and fulls equally. Thanks for sharing.
Video idea: how to calculate gear ratios. Differential gear specs list the teeth count, portal gears specs list a ratio and or teeth count, and transmission specs give you a percentage of overdrive. I’m trying to normalize everything to a ratio, then calculate what my overdrive will be. But I don’t think the numbers are coming out right.
Most RTR's out of the box have the steering figured out nicely. It starts to get weird when you have an aftermarket axle from one company, a servo mount from a different company, then a servo arm from a 3rd company. That's when you need to be aware an apply what's in the video.
Came for the incredible lesson and incredible hair
Soo close to your FIRST 1k subscribers! Keep up these good videos and you will do great!
Thanks for the encouragement! I have a lot more videos planned and I’m happy people are finding them.

Fantastic steering info!
That means a lot coming from you! Thank you kindly.
Great details on trim/sub-trim, thank you!
You bet!
You are killing it with these videos
Much appreciated.
I learn alot from your videos thnk you fornmaking these
My pleasure!
Really enjoy your videos, lots of good info simply put
I appreciate that!
Very helpful...lots of things I never considered ....thanks a lot 👌🤘
Glad to hear that!
You sir would be so good for an RC company
Really appreciate these videos you make. The way you explain the topics based on the rc crawler world is excellent. Thank you
You’re welcome! Thanks for the kind words and checking out the channel.
It’s all in the details
Facts.
Great video once again!
Thank you!

Excellent suggestion. I’m on it.
Pretty interesting
Any time I mess with Trim/Sub-Trim I double check my EPAs
Never hurts!
What RC crawler company is best at steering geometry?
