I a have a Classic Flash and originally I had a Jet Central Rabbit rated at 19 Lbs, it flew great with that Turbine, when it came time to send in the motor for its 25 hour service interval I decided to bolt in my Jet Central Cheetah, all I can say is WOW, at 31 Lbs this thing is a rocket ship. I usually fly around at less than half throttle. The landing characteristics changed also because of the residual thrust.
I would not hesitate to put the Rabbit back in when I need the Cheetah for another project.
So what I am trying to say is pick a turbine that you feel will fit your long term flying goals, a larger thrust motor that is compact will not be a disadvantage as far as weight and fuel consumption because you probably would not be flying around at full throttle. Then is is good if you need it for a larger airframe, if you have no plans to go bigger then the New Rabbit 100 would be perfect at 22 Lbs of thrust.
Good luck, no matter what you get you will like the Flash!
Yep, I agree. I have a Classic that originally had my Rabbit 100 in it, flew great, nice and light, easy to land, actually had to drag it in with some power on. Put my Cheetah in it to use the Rabbit elsewhere. Gained 11oz's overall in weight with the additional 2oz's upfront to balance, about 70km/hr faster...mind you the Rabbit 100/ flash would still do 290KM/hr but, feels heavier, more of a straightline speed plane now if that's what you're looking for.
I actually prefer it with the Rabbit 100 and may put it back in over the winter. It's lighter, more agile has lots of speed. It still has unlimited vertical if you go into it with some speed. The only thing it won't do is go unlimited vertical, fully loaded from takeoff. So, for the way I like to fly it, 22lbs is perfect.
