I plan to use an unregulated 2s lipo for rx and servos. I am using HV servos and a hitec Optima 9x rx. I will be using an unregulated 2s LiFe pack on my ignition. The only place I was ever planning to use a voltage regulator was going to be on my throttle servo but I ened up just getting another HV servo for throttle as well.
If you end up going a route where you need to tone down the votage for just one servo or something you can just put a cheap bec in line with the servo from the rx. valuehobby.com has one for $7.99. I will also be getting my packs there. The LiFe pack is pretty cheap too... like $8-$9.
