If people who have owned both say so then I guess the Saito may use more fuel than the OS 160. However I have owned an OS 90fx and several saito 91s and the saitos used less fuel and were much more fun to fly. The oil mess was about the same. However I would still prefer the sound and rapid, high torque throttle response that you get from a 4 cycle than the spool time of the 2 cycle. I am sure many will disagree with me but thats my opinion. And I vote with my wallet.
