True. I have an FG-11 and it is a very good running, great sounding engine that sips fuel. Can fly for an hour on 12 ounces of gas. I have a DLE30 on a P-47 and am not liking the low end on it, and the DLE 20 I have in a 4*120 has been giving me fits over the past couple years. One day runs great, a week later runs like crap. All my Saitos have been good running engines, and they fall under that, you get what you pay for category.
So this is why I am considering the more expensive FG-40's for this one.
