I ran the TG in my gas truck all last summer and I loved it. It is very smooth and easy to drive. It's not a screamer when it comes to power but it is very smooth. There were also a few other drivers that bought one and it seemed like all of a sudden they turned their game around and were turning some really great laps.
Unfortunately I was barely able to get any better run time out of it than my previous TR. Making 10 minute pit stops I was coming in on fumes. I do run mostly on rather large tracks so that might be part of it. The other reason I think I don't get any better run time is that since the motor is a little lower powered, I am harder on the throttle all the time.
