what is the relavent information

relevant information would depend greatly on what the use is going to be.

of the two, the 2nd one appears to have more available torque.

For a scale rig I would say torue is the one to look for, go after the 6v ratings.
For modern chassis like SCX and TRX-4 etc I would not recomend less than 15kg, same with a heavy ish chassis.

For a CC01 a 6.5kg + servo would work fine.

And like Heartless said it depends on the chassis and useage.

heartless 04-01-2020 08:31 PM

35 a piece? or 35 for two?

either way, not a terrible price

18 each for 35kg coreless for the truck on the right

Big tires may be needing a 35kg servo.
But most of the servos rated at that is nowhere that stong.

But other than that you may need a external BEC as your now powerful servo rob the power needed for your esc and receiver.

I'm running a 25kg servo in my Hot Rod without a bec.
Working fine, but I really need to install a BEC.

When your servo dies, it's already to late to fix it.
A BEC make sure the servo is getting the power need so it won't run hot.
Hot circuit board in servos is a killer for them.
