RE: saito 180 to big for a funtana .90 ?
Finally someone else who appreciates the way to overpower a plane. Sounds awesome. Theres a website called the flying cirkus and there are tons of guys putting 180's in their F 90's. Myself personnaly opted for a YS 1.40 sport but thats because I am addicted to YS's. Beef up everything. CF gear is almost a must TNT as mentioned before there stock F90 gear is 2.5" higher than the stock gear given with the ARF. Use good servos nothing less than Karbonites and a must MG on the rudder. Lots of guys us MG all around I have the 5475 hitec digitals in mine except throttle and Rudder. Seal all hinge points. Plane should be a blast to fly with a powerhouse engine on it. Should weigh in about 10 # or so
