Pumped-up 4-stroke engine technology.

It's the new pinnacle of performance for today's aerobats! The FS-70 Ultimate 4-stroke powerhouse promises smoother, more consistent muscle, thanks to an ingenious pump system that offers consistent fuel delivery, regardless of the plane's attitude. And amazingly, this “pumped-up” power comes from an engine that weighs less than the FS-70 II engine without a pump
