I have a dilemma that I have plenty of time to ponder over...
I am a Diehard believer in DA engines and their business practices and was considering the 100 for my new CHP 34% Extra. However, I live at 6500 feet and the DA doesn't like anything over 26 pounds "wet" for even semi-unlimited performance. My friend has the same plane with the DA and Hyde cannisters and the airplane came out nose heavy to the point that it took 2 2300 mah nimh's halfway down the tail to balance,and it was heavy overall (28 pounds).
My goal with this plane is 24 pounds, but it was seeming to be quite a chalange until I noticed that the BME was almost 2 pounds lighter than the DA and, reportedly, more powerful. Balance might still be a challange, but I am considering this engine.

My question is, does anyone have some comparisons between these engines? I plan on running stock mufflers, again for weight purposes, but RPM figure with cannisters are useful as well.
And while your at it, what planes are you guys putting these on and how was the balancing issue, if any???
