What voltage are you running in your nitro?
I think my XR8 ESC can go up to 7.4V so that might help me get the servo speed a little faster.
For E-buggy I would use the BH9032 and turn the voltage all the way up. I use a lipo, so it runs on 8.4v.
IMO, if you use a high speed servo in 1/8, the gears will strip out. I ran for Hitec for many years and once I switched to high torq, I never broke another servo gear. Before it happened every few months.
Adam Drake has been Hitec's #1 driver for the last 10 years and he used these:
HSB-9381TH Full Metal Case, Ultra Torque, Brushless, Titanium Gear Servo | HITEC RCD USA
Which is the same specs as the BH9037 I use. He used the HSB-9380TH before that and the HS-7950 before that which all have a speed of .17. I used a HS-7950 since 2012, so the BH9037 feels exactly the same except it doesn't get slower as the race goes on.
