Updateness

A burst of activity, and then I go silent again, huh? I really need to work on that.

Anyway, remember those brake shoes I made? The old ones weren’t the problem. Aw well, I still figured a better way to cut the new ones, doing that. The problem was the aluminum collars that the brake disks ride on. Each collar has two flat sides. The flats being how force from the disks is transferred to the collars and axles. As I said, the collars are aluminum. The disks are stainless steel, and it’s their edges that press on the collars.

Anybody seeing a problem here?

Yeah, so the collars had V-shaped grooves worn in them. The left side was bad enough, that the disk was getting stuck in it. I filed the sides of the grooves to shallower angles, so the disks could ride out of the valleys easier. Then, I swapped the collars between the left and right sides of the truck, since they wear on opposite sides of the flats. This has cured the problem, until I can get new ones ordered. Probably gonna do that, in a week or two. (parts for this thing are cheap, but those aren’t the only ones I’ve worn out.) This week, I just ordered a dual motor driver for a model tank I converted to RC years ago. I’m looking forward to driving that again, with a better control setup, than its current kludged together conversion.

Me and tracked vehicles….

I’m still happy with my new radio. I know it’s only been a couple of weeks so far, but there’s been no sign of the controls going south. And, I’m still driving it nearly every night. Braking in a set of new brake shoes means I’m adjusting the dual rate every two or three days. All the buttons being programmable means I can keep the dual rate control conveniently located. I’ve settled on the largest grip on it. I’ve never been a big dude, but most pistol grip RC transmitter handles have always felt a little small, to me. The largest grip just feels best, to my hand.

Wear and Tear

I feel like I should apologize, for turning this in to an RC car blog.

I was having some trouble with the Truck cat’s brakes binding on one side. Low speed crawling resulted in the left side track repeatedly locking up. I tracked it down to the brakes, that it uses to steer. My homemade Formica brake shoes had worn more than I thought they had. It’s hard to get a good look at the shoes, when they’re in place, but I noticed a notch worn into one of them. Once I had them out of the truck, I could see the full extent of the damage.

The New Hotness

Okay, the last couple of posts have been a little negative. I finally got my new radio system on Wednesday, It’s a DX4C from Spektrum. I’ve had a couple of days to play around with it, but the “new shine” hasn’t worn off yet. So, this should be a little more positive.

Tom Petty was Right

The waiting really is the hardest part.

 

My radio has been trying to leave Grove City, since Saturday morning. No kidding. The tracking shows it leaving the “FedEx location” in Grove City at a quarter after four in the morning. The next update isn’t until nearly a quarter till three on Monday.
