RE: Welcome to Club SAITO !
regardless of how much hp saito claims, just what will the 125 spin a 16x6 apc? accordingly to a thread w/m mcconville, he states the 16x6 won't provide 9k and spools up too slow (as i said before i saw a 120 turning almost 9300 and flew quite well), and the 16x4 is a better choice for 3d. i flew the a/c w/os 120/pump w/16x4w @9900. absolute dog, way too slow, and no verticle, at full speed, to verticle would drop out in maybe 50'. the saito 150 or 180 won't meet my filed's DB requirements. the only choice i had left for this a/c is the ys 110 w/16x6 apc.
