My opinions...

1: S&W is not good quality fuel. I live near them and have bought and flown S&W alot simply becuase its the only fuel my LHS sells. I will say its kinda funner buying S&W becuase its interesting seeing 10 jugs of fuel and their all different shades of pink(this is no lie,I swear). The last batch my LHS got is not so bad,but previous batches looked like it was tapped from a drum that was never stirred....scary. No wonder everyone says the quality control there is not so good. Maybe its gotten better recently,but I'm not taking chances anymore and am mixing my own fuel now. I did get some nitro from them at a swap meet which was cheap.....I'd buy stuff like that from them.

2: I've owned one evolution engine,and after owning one and hearing many stories......I'll never buy another. Especially if thier saying you cant run any castor in them,lol. Guess they need some kind of excuse for them. Some guys have good luck with them,but many do not. They look cool,but have bad reputations...even worse then super tigres,and I like super tigres!
