It's a great beginner's car, nothing more. I had one MANY years ago, in fact, only three weeks ago I stripped the chassis of anything useful and threw it in the bin, after it had been sitting for over 5 years. I once took it to the track to try to race it, that was funny. It was all over the place.

If you're looking at an upgrade in the near future, don't throw any more money at the TS4, just save it and get something like an HPI RS4 SS. The TS4N is outdated and unspectacular, whilst a solid basher with a good engine.

16% nitro is a good medium, I would suggest going up to 20%, but remember your engine will need retuning. As for colour, whatever floats your boat...
