Comparing a 20cc 50 sized gasser to a snarling hyper 50 nitro burning monster is like comparing a 90 nitro to a Predator gasser. There is really no way it can come close to the power to weight ratio of a high nitro burning machine. But that not the reason we fly gassers for ultimate power is it? I think our best hope is that it is comparable to the 90 sized gassers already in production. If the performance is much less than the gassers we use now it may be a pretty to look at dissapointment. I do hope I am wrong as I would love a 50 sized gasser too!

Setup is everything, All my heli's can fly far better than I can pilot them

I guess it is all relative to what one is looking for.

For example, my older TSK Gasser, that was very much the same as the Hirobo Eagle II gasser in performance, were both a lot heavier then my Predator Gasser and both came with the rather low-powered Tanaka 24 motor. It flew about like a 30 with the older OS 28FH or 32FH engines. I would not want to try even rather basic 3D flight with any of them. Sport aerobatics (loops, rolls, inverted and 540 stall turns would be about it)would be about their comfortable limit.

On the other hand, my relatively (for 90 size gassers) light Predator gasser with the G-231 engine and V1 muffler is a much superior performer in the 3D arena, not up to its' 90 nitro brother, but more like the 60 version withn a higher torqued engine.

So I would expect that maybe the Z-20 powered Gasser with 620 to 640mm blades would fly much like the heavier 50 nitros (e.g. Evo 50) did with the OS-46 or initial OS-50 (non-hyper) engines, which is still quite formidable. This would not be like the NX-50 with the Hyper or YS50, but still probably more capable then 80% of the flying community will ever become.

And of course all while costing only 10% as much for fuel as their nitro bretheren.

Could anyone post their experiences with aggressive 3D on a Predator gasser? Number of flights, capabilities, longevity of parts and videos would all be welcome.

It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.
