Hey Condor the original byron P-51's actually used standard servos from way back then a lot of todays equipment is great but a lot of overkill. In my new BYRON P-51 I will be usung all FUTABA 3305 servos for the elevator, in fact I' am changing it to a center rod for the elev. so it does not show, also 3305's for the airleons and flaps and rudder then 3004s for the throttle and tank drops. The retract servo is still up in the air . I might use a 3004 for the retract if I use the up valve, but I still use the old original byron (ACE) 7 second servo and dual spool valve in my old P-51 and I never have had any problems with it, not bad for over 13yrs. I still have both valves so I' am still undecided. You can use any servos you want, if you feel confortable with the digital or higher end analog servos you can use them also. My old one has the old FUTABA quater scale servos for the flaps and airleons and elevator and standard servos for the rest except the retract. The FUTABA 3305 servos have plenty of torque to handle the BYRON P-51 with dual ball bearings and netal gears. This is just my opinion. Oh I also saw a sale on the 3305's some where it might pay to check it out and they will not break the bank.
