Hey Rcswamper
The RCGF 50cc engines are one and the same.... (all high performance)

.
The new 50cc engine model that have just been introduced are proving to have a higher power/thrust curve than the previous models. The factory is taking the "voice of the customer" seriously, listening, studying and then acting to what is needed. The result is a no nonsense, "take no prisoners" engine that does what the designers intended it to do - fly your aircraft smartly, reliably, with no drama, and lots of power to spare.
