Hey I just got my Razor, The bell crank was sloppy so i got heavy duty horns for more throw and i opted to get hevy duty clevis's for the area around the evelvator. It works awesome. Oh, Yeah what the heck is up with the small ailerons. Im using a O.S 70 with a perry pump to power it. Another thing invest in a prcision servo for the elevator with a long arm for even more throw! Happy Flying
