Saito's are WONDERFUL!

The pilot's who own them need to learn a bit more about the engine though.

Saitos will run almost completely out of tune.

Because of that people will attempt to fly them usually far far too rich, and then complain about poor transition, idling problems, etc.

Unlike other engines they WILL run tuned so horribly... but once you have them set correctly, they sip fuel lightly, produce a lot of power for their weight and are extremely reliable.
