Steering drifting off center over a few weeks and your first instinct is to blame the servo or linkage. Half the time it's neither, it's trim and endpoints creeping from normal use. Here's how to actually reset them: https://senditslow.com/guides/transmitter-setup-basics/ #RCCrawling #RCUpgrades

Added brass wheel weights behind the wheel faces on the SCX24. Cheap, ugly, nobody sees them once the wheel's on. They add unsprung mass right at the corner, which is exactly where it matters for keeping a tire planted on an off camber ledge. Small part, real difference. #SCX24 #RCUpgrades

Put machined aluminum shock caps on the SCX10 instead of the plastic stockers. Ride felt the same day one. What changed is no more oil film around the shock body after a hard session, since the plastic caps were weeping first. Boring but it works. #SCX10 #RCUpgrades

What's an upgrade that took way longer to install than you thought going in? Mine was an SCX24 servo swap. Twenty minutes of wrenching, forty five of unplugging the wrong connector twice. What ate your afternoon for no reason? #RCCrawling #RCUpgrades

I regret this upgrade: a winch on my SCX24. Looked fantastic. Used it in anger twice, both times badly, and the rest of the year it's just nose weight on a truck that already tips forward too easily. What's your regret? #SCX24 #RCUpgrades

Injora soft compound 1.0 tires on my SCX24. Same diameter as stock, just softer rubber. They grip edges the stock tires skated off, and since the size didn't change there was no gearing or steering tradeoff to absorb. #SCX24 #RCUpgrades

SCX10 brass axle housings drop the center of gravity and add weight right where it helps traction, not just where it looks good.

Ever install an upgrade then quietly put the stock part back on? Did that with a servo saver spring, hated the feel, swapped it back a week later.

SCX24 stock center driveshaft is plastic and flexes under torque on 3S. Aluminum is cheap and it's usually the first thing that fails once you push real power.

TRX4M brass portal knuckles put weight right where it helps, down at the wheels, not just heavier everywhere. Small swap, noticeable difference on uneven ground.

SCX10 stock links are fixed plastic, why your geometry is stuck where Axial decided. Adjustable aluminum links aren't flashy but let you actually dial it in.
