Three Things I've Changed My Mind About

I’ve been writing this site long enough now that I can go back and read things I believed a year and a half ago. Most of it holds up. Some of it doesn’t, and I’d rather say so out loud than quietly let the old opinion sit there looking authoritative.

Here are three things I was wrong about.

I Used to Keep the Truck Dry

For most of my first year I treated water like a hard boundary. Damp grass was fine. Anything with standing water in it, I drove around. I had a vague memory from the nitro days of everything I owned rusting, and I let that memory make the decision for me without ever checking whether it still applied.

It mostly doesn’t. A modern micro crawler is not a sealed submarine, but the parts that actually care about water are a short list, and they’re manageable. The electronics in an SCX24 or a TRX4M are the thing to think about, not the chassis. Once I understood which components needed attention and which ones genuinely do not care, the trails I’d been avoiding opened up. Creek beds are some of the best crawling terrain there is. Wet rock changes the grip problem completely and makes you a better driver because you can’t muscle through it.

I was not being careful. I was being superstitious, which is different. If you’re doing the same thing, the water and snow guide covers what actually needs protecting and what you can stop worrying about.

I Thought the Stock Radio Was Fine

This is the one I feel most strongly about now, because I told people the opposite for months. My position was that the included transmitter works, it makes the truck go, and spending money there instead of on the truck was beginner misallocation. Buy driving time, not gear.

What I missed is that the stock radio isn’t bad at making the truck go. It’s bad at making the truck go a little bit. The throttle curve on the entry-level units is coarse at the bottom, which is exactly where crawling lives. You’re not asking for half throttle. You’re asking for six percent, held steady, while a tire loads up against a rock face. A radio that can’t resolve that difference makes you feel like a worse driver than you are.

I spent a long time blaming my thumb for something the transmitter couldn’t do. When I finally swapped, the thing I noticed wasn’t power or range. It was that small inputs became real inputs. If you’ve plateaued and you can’t tell whether it’s you or the rig, the radio upgrade guide is the piece I’d read before buying another part for the truck itself.

I Called Brass a Cosmetic Upgrade

I lumped brass in with all the shiny aftermarket stuff I’ve complained about before. Machined parts, nice finish, sold on looks. I assumed the weight talk was marketing.

It isn’t, and the reason is scale. On a truck that weighs a couple of pounds, adding a few ounces low in the chassis is a big percentage change in where the center of gravity sits. That’s not a subtle tuning nudge, that’s a different vehicle on a side hill. My SCX24 stopped rolling over in places it used to roll over, and I didn’t change my driving at all.

What confused me is that brass looks like the parts that don’t work. It’s visible, it’s machined, it costs real money. But it’s doing something structural rather than decorative, and I sorted it into the wrong bin because of how it looked in a photo. The brass upgrade guide explains where the weight actually belongs, which matters more than how much of it you add.

What the Three Have in Common

I didn’t test any of these. I inherited an assumption, or I reasoned from something that sounded right, and then I repeated it confidently enough that it started to feel like experience. All three fell apart the first time I actually tried the thing.

That’s the part worth taking away, more than the specifics. This hobby is cheap to experiment in and the feedback is immediate. You can find out in an afternoon.

I’ll be wrong about something else by next year. I’ll tell you then.
