#4584: What this thing needs is BRAKES.

I discovered that I can't do donuts (as I had hoped) nor can I get it to spin. The tires get just enough bite that it will either climb a slope, or sit there and strip gears (gonna have to make sure the drivetrain is cinched down). The tires won't spin, which--on a decent slope--would let me crab it sideways.

I can do none of the maneuvers I had hoped I could. Of course, the snow is different than it was lo these many years ago when I first had the idea; back then the snow had a hard layer of ice on it, enough that it had a semi-glossy sheen; this is just snow that partly melted and refroze.

No, getting the hose out is beyond the scope of this project.

Even so, I spent about fifteen minutes outside--until my fingers went numb--running the thing around on the snow, and then on the driveway. On the driveway I was able to get a little air when I ran it over a clump of ice. There's a place where snow makes a quite natural ramp to the middle of one of the bushes, and I was able to get the thing to climb about halfway up before it started stripping gears again. (Something's gotta be loose in there; it never did that before. It would either go, or not go; it would not go GRKKKKKK.)

I'm really glad that the issues I was having were due to low batteries. I should have known better--the batteries had charged for perhaps an hour or so, when they typically need about twelve hours at the first charge, and although the 9V battery provides power for the transmitter it is not the sole power source, and if the C cells are out of juice of course the operation will become unpredictable.

It's just that I'm used to things being problematic: I decide to get my RC truck out, so I buy new batteries, and then the truck doesn't work. That scenario is all too typical.

Anyway, truck works; I may or may not take a video of it in action, but it's hard to do that when both your hands are occupied with hooning the truck around. Whatever video I take is not going to be very exciting, but if I take it, I'll YouTube it.

...maybe what I ought to do is take it over to Og's place sometime soon and hoon it in his back yard. That might make for some interesting video; they've got quite a slope over there. Of course in high gear the truck would not be able to climb back up, so I'd have to go retrieve it after each trip to the bottom of the hill.

High gear, low gear: the thing's got a dual-range transmission in it, selectable via a switch on the bottom that changes gears in the gearbox. It's zippy in high range but has no real torque available; in low range it can climb hills but it's not fast at all.

In either mode it scares the socks off the cat. Heh.
