I got a ORCA speedo and 7.5 turn combo for my Cougar. The speedo let me down after 5 mins practice at TORCH the other day - possibly spiked it after breaking the servo..... However the motor is awesome!!
I have replaced it with one of these

From what I understand it is the same as a Speed Passion 2.0 GT but about half the price??!!! Maybe worth a look?
