It has previously been claimed that problems with the JS engines occur around the gallon mark. I have put 2 gallons trough my fully modded JS, and it has been nothing but good times. Very easy to tune, performance is great and really enjoy the faces turning pale on my fellow rc drivers when the see the performance and hear the price. If it stays this way you have a returning customer for years to come.

For the record I'm what best can be described as an enthusiatic amateur and not sponsered by anyone besides my paycheck . I just believe that when you get a killer product it's a good thing to spread the word.
