6-19824 Target Launcher Car at constant voltage?

From Dale H's blog, a way to reduce voltage using diodes or bridge rectifiers. Maybe Dale H will be along to answer any questions you might have. He has a lot of good info there on his blog.

Just noticed my link didn't make it, here it is again: Dale H's Blog - Reducing Voltage

Get a bunch of 3A diodes.  Make two chains of five diodes with all the bands facing the same way.  Put the two chains of diodes in parallel with the bands on one facing the opposite of the other.  This whole assembly goes in series with the center track pickup.  That whole assembly will drop the track voltage about 3-4 volts.  You can probably use 1A diodes, I just don't know for sure how much power that car takes.

If you do eBay, search "10 1N5406".  You can get 10 3A diodes for 99 cents shipped.  It takes a couple weeks from Asia but you can't beat the price. 

If you simple can't wait, Radio Shack has 3A diodes for $1 each.

I still prefer ERR MiniCommander installed inside the balloon car.  Your able to turn it on/off via remote and adjust the air flow for that just right amount to hold the balloon in place.

I've converted a couple of mine, and still have one I was going to let the LHS sell.

I have one I put TMCC in, works great that way.

I think the ERR Mini Commander idea is the way to go. Wasn't sure if they would work with this car. Anything tricky to be aware of when doing the installation? 

Not really, it's dirt simple as you just have a motor to turn on and off.
