Wow! Wood screws? I will have to think about that one for a while. I would hate losing $2000.00 worth of equipment due to a horn being yanked out in mid flight. I even bought the steel horns with the idea that the steel would produce less friction than the nylon ones. (Not that the nylon ones are bad or anything), but Ill think it over. On another note, I have read several posts where the Saito 125 is being compared to the OS 120 but the posts refer to the fact that the lighter Saito would be of no gain since the lighter front end of the plane would require added weight, therefore eliminating any benefit from a lighter engine. What about the batteries? Can’t those be placed more to the front? Could they be placed on the firewall if necessary? And what about the difference in BHP between the Saito 125 vs. OS 120?
