2M bird is the only way to go. Given you could use the YS or OS motors, and that the servo requirements in our price range are the same given .90 sized or 2M, there is really no price savings. Plus, bigger flies better every time. One or our F3A guys who flies really, really well needed to fly a .90 sized plane for a while when he was reparing his Smaragd. There was no way he could compete against the same competitors flying their typical planes. The Focus pure and simple offeres the best, proven performance for the money. If a good used plane is not available locally as mentioned before, the Focus, YS160,YS140Sport, OS160, OS140RX, and digital servos, would give you top performance with a variety of cost options. If you are going to fly FAI, the YS160 or OS160 are the only two motor options that have the power to fly through any weather condition (IMHO).
