If you were flying back in the mid to late 70's then this is the radio that you "Lusted" after. I know I did Features like servo reversing so you didn't have to open up your servo and switch the outside wires to both the pot and motor. Dual rates and a slow roll button. Retract servo end points. That, and 2 meters, one for battery voltage, one for RF. Yup that was state of the art back then. And for just $749 you could have one too. Proline open gimbles, nice, but no ball bearings.
Luckily whoever stored this one removed the batteries. I powered it up and it still works. Legal frequency too. Servos certainly seem slugush compared to todays servos.
