Now why in the world would a YS need to be fixed every year? I don`t send any of my cheap engines to be fixed every year . As a matter of fact I had both Mag and TT for about 6 years and both still going strong. Whats up with that. Now I`m aware of the power of Ys engines. But why is it they have so much problems. Every person I know with one have problems. One day they are good the next they can`t stay runnng. $350 I don`t think so I`ll stick with $179 Thunder Tiger or $150 Mag. and fly all season and the next and the next.
