Do know that they can be much heavier than other drivetrains depending on their features, so they aren't suitable for some games.
We went from concept to working prototype in about 3 weeks during build season this year. We didn't do any prototyping or design on that type of drive train before build season started. Do your research and don't be afraid to ask for help. Our drive train wasn't perfect but it did very well and we had to perform very little maintenance on it all season.

Also as noted about it's called Tex Coast Drive now.

There are trade offs in every train and depending on the features you put in it can be lighter or heavier.
