Dynamite Machined Aluminum Futaba Servo Horn (Red)
I just received that Horn and it doesnt fit in the 25(futaba type) tooth servo, impossible to screw it on, it can't be the servo because i had other 25 tooth servo horn with other length and they fitted well. So i can do nothing with it, wasted money!
