A Saito 125 will not be too heavy. I have run the YS 1.40 on mine. Several others have done so as well. I have seen one fly well with the bigger Saito. I would sugest you fit some ply doublers if you go beyond a 110.

Does any one know engine used in the vidoes? this looks like a kick ass bird that can be as mild or wild as you want depending on engine size installed. Great price now $200. am ordering one for this flying season. I have a 91FX but a Saito 125 might be the ticket if not too heavy. Thoughts anyone?
