How dose shock position, placement or angle affect deflection / flex, body roll and stability characteristics, is their an optimal shock position and or angle to maximise crawling performance?
My roommates saw me watching a video with RC trucks driving and everything is normal. My roommates see escalated defining of variables and equilibrium of forces condition as I measure my TRX4's flex just to tell them that the included springs from the factory are the proper rate...
Your shock absorber calibration calculation is good from a mathematical point of view if and only if the shock absorbers had no friction. Which is not the case, especially on the lightest crawlers (under 3 kg) for which the friction of the joints is important compared to the force of the spring. On mine (2.5 kg), I fitted traxxas GTS 0.22 springs (Ref 8042 - yellow) to have 50% SAG. With your calculation I would have used 0.30 (too stiff)
You are right. My calculations ignore friction, especially static friction (stiction). However, if you get a suspension system with little stiction, and consider slow movements only (to ignore dynamic viscous effects), they should be a good estimation for a good spring rate.
Thanks for sharing your know how 👍

This was crazy to watch but was very helpful to know the stock shocks that come on the trx 4 are the right balance. Thanks for the video!
Thanks for watching! And for your positive comment, with which I fully agree.
# 120 !! 👍😁 - I am "brushing-up" on the whole shock set-up process, thank you !!
😉
This is some next level nerd stuff! I love it!

Great interesting video, thanks my friend!)🤩💥💯👍👏
Many thanks!!
For Most of Rc lover what they actually do is trial and error
