Well Im glad the thread helped out, thats what we are here for to help each other out and talk about the hobby.

While I do think the box is the way to go, there is another option.
ITs called the Yank Eliminator, these came out a couple of years ago and its basically a one way in a shaft that attaches to your electric drill.
You would remove the pull start and I guess leave the shaft exposed (not a good idea in my opinion) and just place the one way over the shaft and pull the button on the drill to start the motor. I have never used one but they are not that bad on price. $30 I think.

To be honest with ya you could probably make one of these things with an old one way bearing.

Anyhow, the Starter box is the best option in my opinion, they will last forever no matter what you do to them. I have had my ofna box for years and its still got the original motors and such still going strong. I did replace the rubber wheel at one point but thats about it.
Tower carries the Ofna boxes from around $60 or $70 (guess) and I would suggest getting a gel cell to go along with it. I think they actually have a package that has the cell, panel and all.

The gel cell is a 12v battery that will hold a charge for about a month. They are very easy to take care of...basically a 12volt is fully charged at around 13 or so volts, when it gets down to 12.5v just put it on the slow charger over night and you are good to go for quite some time.
You can also power a Glow heater off the 12v (need power panel) and your field charger.
I love my 12volt because I can charge my batteries on the way to run my cars or on the way to the field to fly.

The other option is to run 2 7.2volt battery packs which will cost you about $30 for 2 cheap ones. They usually wont last for a full days worth of racing unless your motor is perfectly tuned. If you have issues and end up hanging around on the box trying to start your car, you will drain them quick. Gel cell will fight you all day basically and still have some left.


Good luck
