Hello
I've just a bout finished building a Robbe U47 which has a engel piston tank fitted which means I needed to relocate the servo for the rear dive planes to the wet area of the hull.
I've noticed there are a couple of different Hitec Waterproof servos on the market one being a HS-5646WP which is digital programmable and one is a HS-646WP, can somebody please explain the digital programmable part and explain which servo would be better suited to the application. The servo will be controlled by a pitch controller to keep the sub steady whilst underway and the radio I'm using is a Hitec laser 6 with a HFD-08RO reciever.
Thanks
