Yes, she does have some Firebird resembleses..
The smaller liberty-S can hold up to 92mm Turbine diameter.
The bigger Liberty-L certainly works with a 120 - 160 Turbine.
I think Keith is the most experienced Liberty-S guy who can tell you more on how she flies.
Like I said, i am waiting for mine to arrive.
As soon as she's in, I will update this thread with my build and flight experiences on this jet. (with YouTube videos to support it)
