I would prefer not to have to add a second voltage regulator as I have to use one for the MPI Servo reversing Y for the flaps. They JR are also $60 a pop, where the Hitecs are $28.
The Hitec HS75's are great servos. Will last years. Will work with the newer higher voltage battery systems...etc... I have several.. I've used one in every retract application I've done. You can't go wrong.
I'm not familiar with the JR 791 servos you're replacing.. but do be aware(you probably are already).. the HS75's are full 180degree rotation.
I'm curious about the regulator you're running for an MPI servo reversing Y for your flaps. I have an Expert brand(Horizon Hobbies) reversing-Y in 2 of my planes, using LiFe batteries, and have zero problem.
Good luck with it.
