I am runnning the new serpent 733 and have been looking at the HS-7940TG or the HS-7965MG. I will be running them with the M11X Airtronics radio. Which one of these 2 would be the best option, or is there a better servo Hitec servo that would better suit my needs. Also on the both of the write-ups for the servos on A main hobbies it states that the "features" are only programable with the HFP-20 or HFP-21 field programer. The M11X will not be able to program these servos? One last thing the HS-7940GT can run 7.4V, but how do you run your set-up if your reciever (airtronics) cannot handle that load. I know with previous servos it was easy just run the voltage regulator from the battery to the reciever. Thanks for your time

The 7940TH is going to be your best bet as it has titanium gears which are virtually unbreakable. Your M11x will be able to set upt the servo through its own programming, but the servo can be programmed by itself with out the use of the radio. Our programmers are mostly needed by airplane applications rather than surface. If your receiver cannot handle the high voltage set-up, there is a way you can by pass the power through the receiver and run the high voltage direct to the servo. Basically the only wire from the servo to the receiver will be the signal wire, and the power wires from the servo will go direct to the battery. It will take some wiring and a programmable BEC to accomplish this.
