what throttle servo should I use for a 700 nitro?

What size servo is meant for the heli?
If the servo mount us pre-cut for a standard size servo, then any standard size servo will work.
I've seen some nitro heli that have a mini-servo mount pre-cut, then you can use any mini-servo.

You don't need a high speed servo or a high torque servo.
I use Align DS-425M mini servos on my Goblin 700BN and Goblin 570 Nitro conversion. But I had some old Custom Heli Parts adapters plates to fit a mini servo to a standard mount.
On my Protos Nitro 700, I use BK Servos DS-7001HV, bit that's only be cause I had one laying around.

I've used a bunch of different servos for the throttle. But you don't need anything special.
But, if you have a 2S LiPo for power, make sure you are using HV servos.

I’ve had a standard Hitec 425bb and now a hs digital and I can’t tell the difference
