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!
