Super cool! Thanks for sharing. I've always thought it would be cool to develop some type of zip line for a camera on the league races. It would make for some cool highlight videos.
Well done.

Video Taping Wheel Movement

Very cool idea indeed. On that track (3 lane) you could make a frame on two cars or maybe 4 connected together via the frame and mount cameras on front, top, rear, sides, where ever you wanted really...and have multiple synchronized views of the interactions of wheels, car, axle and rails. Would be tricky trying to get it to go the same speed as your car though...let alone getting it aligned to allow it to match the speed of the car.
Also it looks like you may have some toe in on the left rear wheel (as viewed from video) it migrates in to the body at the start and might be what is driving the steer the wrong way (the light drift probably helps expose this). Not sure though as it looks like your hand may have kicked the rear of the car to the right at release...so some other factors might be at play there. The wheel then migrates back out, but I think it may have been pushing on the rail at the start, but can't tell since the camera couldn't capture that interaction early on. I think once the car is up to speed it then keeps that left rear out because it is up to speed and not going slow. Even after the wheel migrates back out it seems the DFW stays on the rail for a bit before being forced to steer the other way. I suspect alignment issues.
Well done on the video experiment though. I wish I had more time to play with this hobby. Kids in sports just don't mix well with hobbies.

I would LOVE to see this same shot done with a car that's done well in the league races, to contrast and compare the wheel motion close up.
Kinser, can you send Wayne one of your BASX cars to test with? /images/boards/smilies/wink.gif /images/boards/smilies/wink.gif /images/boards/smilies/wink.gif

You're right!
Kinser, please send TWO Basx cars, so we can use one to mount the camera on... /images/boards/smilies/wink.gif

I would bet most pros run way tighter wheel gaps so the migration wouldn't be so obvious. But it'd still be a cool video!

It's a moot point. The camera is intended to see what the car is doing while running. Gathering time data is another issue.BulldogRacing said:
By the way, I really liked Skippy's idea about a zipline for the camera. /images/boards/smilies/thumb.gif
Now I'm trying to justify buying a Mobius camera to myself......I see they offer a shielded version.......hmmmm.
A while back, I dropped a hint on an ongoing project;

I don't think I ever followed up with a full report, but that hole in the car was for a 1/4x20 mount for a keychain cam. Let me look for the video, upload it and link it in in a later edit.

Here's the video;
Later v2.0 included more weight to allow the care to overcome it's poor aerodynamics to keep up with the other cars being filmed. I'll have to look for photo's of the car with cam mounted.

Pretty cool! Do you have any specs on the camera that you used? Also, did it seem to me that you were able to change the angle that the camera filmed?
I used what is commonly known as an "808 Keychain Cam". I'm pretty sure mine is a #26.

Mine came with a holder that was equipped with a standard 1/4"-20 mounting stud that allowed me to bolt it to the car and rotate it on the screw as needed.

Oh, very cool indeed. Now I have to stop myself from ordering one to play with...too many toys available today...too many toys...
That seems like an awesome tuning tool. It adds a whole other aspect of tuning that it seems everyone will need to master to be competitive in the future.
The wheel gap in the video is large, but, is it helpful to have it large so he can see what the wheels are doing? Will the wheels act/migrate differently with a larger gap as opposed to a tighter gap?
