I just started using the system myself (2100KV motor) in an 8ight buggy. It is strong and ran very cool. Especially for the price you paid it is worth it. I learned the hard way if you read my other post about the system, you need to tune it down from the default setting. I had never run a buggy before or one of the Losi systems.

First run I just messed around in front of my house never hitting WOT. Second battery I went to an empty parking lot and let it rip, it blew the foams out of the Losi factory mounted tires. So it is a good strong system to say the least.

The software took a call to Losi to get installed, but once on it works well enough. I do like the Castle software better, it is a little better polished. However Losi so far has been prompt with the updates and they seem very serious about refining the system.

It does not seem as smooth as Castle, but that could be me needing to work with the ESC (and changing my center diff fluid) .

Over all I am happy I tried it, I think it is great that so many companies are producing 8th scale products, should be good for us in the long run.
