RE: t bought FUNTANA S90
ahmet;
I have the F90 with a very powerfull Saito 100 in its nose. My F90 balanced out perfectly with no extra weight needed and the battery/ receiver right at the wing tube. I even have the heavier metal geared servos in the tail and wing and still weigh not more than 8lbs 2oz. It depends all on what kind of flying you intend to do. If you are in heave 3D stuff and are really good at it, than go with the YS 110. If you have more average pilotskills than go with the Saito 100. I fly mine hardly beyond 1/2 throttle. I hover my F90 also 1/2 throttle and can easily pull out of hairy situations. Just my two cents.
