Hi FormerCA...
I have a ZDZ80 was in my 26.75 lb Edge 540T... flew it well... and would pull out of a hover slowly...
I am moving it to a Lanier Laser 200 closer to 22 lbs...
I also just got a BME 110 Extreme... it really is an unbelievably small engine weighing less than 5 lbs with ignition AND mufflers... I also have a DA-100 both of these have homes, but no time to get it done... I'm gonna put the DA in the Edge and the BME in a Wild Hare Extra...
For a smaller, lighter plane like the H9 Extra, I'd sayt he 80 would rock it... but if you wanted carzy power, the 110 Extreme would offer it without any additional weight...
We'll have to see if the 110 can last ling with all the weight reduction...

uhoh, that sucks-leaking fuel-
Hell, I might go with a twin-i'm just now in the process of gearing up so the engine choice is up for grabs.
