I have a 3PV with R304SB Rx and just replaced the stock analog servos on my OG Baja with digital ones. Savox SG-1210SGP-BE for throttle/brake and SG-0236MG for steering. I'm still using a 6v Rx batt for now

Can these be used with the T-FHSS high-speed mode, and should it be automatically selecting that (it isn't) or must I do it manually?
 
Hey,

T-FHSS dos not mean high speed, the "T" means Telemetry so you can use telemetry modules such as heat temp sensor/rpm counter, voltage etc the "FHSS" is basically a signal hopping feature which basically eliminates any kind of interference, one of the main reasons why most rc pilots prefer the Futaba systems over anything else.

In terms of speed, its usually down to the voltage, this receiver supports upto 8.4v and referred to as HV (High Voltage) meaning you can use lipo packs or packs upto 8.4v) as opposed to the standard 6v packs ...if you look at servo specs, you will usually see different groups of specs depending on voltage, 6v, 7.4v etc. the higher the voltage, the higher the specs such as the Speed of servo & Torque.

So in terms of your situation, yes you will be fine to use those servos with that rx, however you servos will not be working to there full potential due to the 6v battery being the bottle neck, if i was you, switch to 2s 7.4v lipo, i did this and the difference is huge in terms of speed/power for the servo which is around 15-20% increase from 6v to 7.4v.

Sorry I should have been clearer. The 3PV can be set to either T-FHSS or T-FHSS <high-speed> and the instructions are vague on what requirements one needs to meet to do the high-speed version. Primarily, I've gotten conflicting info on whether it can be any 333h digital servo or had to be a Futuba one.
