Fast vs slow servo? Short arm vs long

[chapinb]

If you have a slow servo with big torque, you can make up some speed with a longer arm. With a faster servo, you can gain torque with a shorter arm. My question related to what one is better? Im leaning towards the weaker/faster servo with a shorter arm. Logic? I don't use all the throw in my xbe currently. With a short arm, I can utilize more throw while still keeping the torque up. Thoughts?


Im looking at the Spektrum 9020 and 9010 specifically.


S9010 has 771 oz/in of torque at a speed of .14 sec/60 deg at 8.4 volts.


S9020 has 1050 oz/in of torque at a speed of .20 sec/60 deg at 8.4 volts.

I don't think you need more with 771 oz of torque. You are already well over what is general used.

Probably true. But isn't overkill more fun?

Still, the question remains. If it's easier, use the savox 235 and 236 as examples. The 235 on 6v is a little under powered, very quick for a 1/5. With a short throw arm, would it be any better than a 236 with a longer arm? The 236 wouldn't have the benefits on full range of motion. Or is that a benefit at all?
