RE: Welcome to Club SAITO !
40 minutes to have a stone reliable engine, that's a trade off that's worth a million times the little bit of effort and time it takes.
It's kinda hard to describe flying beyond saying, "I went to the field and flew my Cherokee 40 and it flew great" or I flew my RCM 40 with a Saito .56 and a ProZinger 12x7, it will fly nearly 30 minutes on the 11 oz tank.
