RE: Saito 100 Ti inline twin cyclinder-questions
I have a 200Ti. Except for size, the design looks to be about the same as the 100. I haven't seen a 100Ti run yet.
Power for the 200Ti is somewhere between a Saito 150 and 180. But it runs glass-smooth, has an incredibly low reliable idle and it sounds great. Break-in took a good bit of time.
I would guess that a 100Ti would probably fly a 60-size plane "scale". The plane would need to be carefully selected to make sure that the engine would fit in the cowl. And for obvious reasons a plane that tends to build tail-heavy would be better than one that builds nose-heavy.
