…you’re on camera!

My first attempt at mounting my helmetcam to my RC truck didn’t work so well: it was velcro’d to the flexible body and shook around too much. This time I screwed together some 3/8″ dowels and other scrap wood to attach the camera to the frame, by spanning the front and rear body mounts.

 

 

The camera pokes a bit farther through the windshield now (so it records less of the hood) but it’s held on with elastic bands… so if it gets hit it can slide back into the body:

 

 

The video was better, but still very choppy. It’s never going to be perfectly smooth when the truck is flying across a lumpy lawn on little 5″ wheels. So I also washed the video though a VirtualDub plugin called “Deshaker“, then played with cropping and resizing the video to get this second demo clip:

Deshaker nudges the video frames in various directions to try to stabilize the image, but it leaves black bars around the edge to the scene (i.e. if it moves a scene a bit to the left to remove a shake, it backfills an empty black section on the right of the screen). So raw Deshaker processed video has black bars dancing around all 4 sides of the screen as it tries to stabilize the image, which is distracting. To get rid of the worst of it I cropped the 1280×720 video down to 1030×580 (so I lost a bit of my peripheral vision), then resampled the result back up to 1280×720 again. The resulting video is a bit less crisp… but a lot less shakey!

Shakeycam…

The truck body that came on my used Stampede RC truck doesn’t owe the world anything, and won’t be winning any beauty contests. Which is why I started to look at it… then at my ContourHD helmetcam… then at an Exacto knife. A plan was formed!

I cut a hole in the windshield and crazyglued the extra plastic to the roof to make it a bit stronger. Then punched 4 narrow slots in the lid and threaded some velco through. TaDa!

 

 

 

 

It was just starting to spit rain out and it was getting dark, but I just had to test it right away:

Body rattled a lot, and the helmetcam battery kept dying, but you get the idea. Perhaps next time with the body held on tighter… and when it’s sunny out… some creative editing may capture some good clips that aren’t vibrating so much you get a headache watching it. I want to get 2 RC cars together and film one chasing the other!

Followed me home…

This week I had broken my big green RC car (RC8) and was waiting for parts…. but I still had RC on my mind. Friday after work I was scrolling through some local forums and came across a great deal on a Traxxas Stampede VXL 2wd: one of the vehicles that was on my shortlist when I wanted to get back into the hobby. Yes… I already had one car… but it was a bit more for racing and less for “bashing”… and the price was right (the seller had recently sweetened the deal by adding all the electronics, making it Ready-To-Run)… and it was a 30min drive away… and it can never hurt to have an extra vehicle for when you plow the first one into a fence 🙂

So I picked it up Saturday morning:

 

 

It needed a little love: some new body mounts, front springs, and to put the off-road tires back on (it came on street foam tires). Then, because it was raining, I charged it up and took it down to our underground parking garage. I was looking forward to bombing around on something slower than the RC8… with a bit more clearance to get over curbs, and something I could wheelie without regret! 🙂

Well… I was partially right: it wheelies on demand… had more clearance… and it’s fun to drive with all the handling quirks that come along with a 2wd monster truck with a high center-of gravity.

But it’s not slower.

In fact… I think it’s faster. As in drive-on-the-highway-keeping-up-with-traffic fast!

I’d need a second driver to know for sure (race it against the RC8) but for now I’m going to drive the Stampede in “training mode”… meaning it limits itself electronically to 50% power. It’s still plenty fast, and handles more like I was expecting. And I definitely have to put the wheelie bar back on… in sport mode you can be rocketing along at 80% power… and if you floor it it will still power the front off the ground and flip itself on it’s back. Crazy!

(but fun! 🙂
