Lightbulb Project Vette...

Okay, so I've been lurking around various RC boards for a while and have never seen anything like this attempted. It's more of a "can I do it" project than it is serious. But so far its going pretty good.

I have a New Bright 1:6 corvette...lol.

I'm attempting to hop it up to being at-least a vaguely worthy opponent for mostly just parking lot races/small tournaments.

...I'm also attempting to do this as cheaply as possible. Just because it's more interesting.

I'm mainly just wanting opinions on what to use, calling me crazy, ect.

onto the build...

So, I've ripped most of the stock equipment out (well the board went when I fried it due to a water accident.) It's been replaced with a cheapie dollar general RC toy board I stripped out of RC buggy.

I haven't gotten around to a speed controller as of yet, but I allready have an idea how to wire one up with radio shack parts. (Using throttle on time instead of throttle positioning, as these boards do not support that haha. will be "interesting" to drive)

I already have it assembled, I'm just adjusting things as I go.

Motor: http://www.johnsonelectric.com/media...&IdProduct=493

Batteries:
Engine: 2x 12v cordless drill batteries in series to over-voltage that motor to 24v.

Board/Relays + steering: 6x AA (Soon to be replaced with a lightweight NiCd I salvaged.

The motor is controlled via relay to save the board since the power would be much for any type of "size-able" transistor network.

Right now I'm working on the gearing. It came with extremely short gears, 3 deep with one double geared. So I wont bother figuring out the ratio of them. I'm eliminating the second (double) gear to have a strait 2 gear setup. The rear axil is solid (ie. locked) so power-sliding well will be an absolute must.


All opinions are welcomed I'll post pics if anyone wants me to. I doubt to many care so I won't bother right now.

P.S. I already "had" to eliminate reverse so I can use the reverse signal to operate a engine brake. I also might add "band-drum" brakes onto the axil. I haven't decided if it will be needed yet.

Wish me luck,
K7

[Edit]
After I get the gearbox modding done, I might go back to a 12v setup if 24v is heating the motor under that load. So far I'm not having any particular heat issues unless I stall it.

Alright, I'll take a few pics when I get it reassembled, the gears for the cheap steering mechanism blew out on me so I've been tearing it down.
