6.5 kg Servo for 2WD Buggy. Enough?

[skom25]

Hi,

As in Topic. Is 6.5 kg enough for 2WD Buggy? I will run it only on asphalt.

Yes.

More than enough. For reference, I use basic Futaba S128/148/3003 servos in almost all my buggies, stadium trucks, and 2WD monster trucks. They're all right around 3 or 4 kg-cm, and they steer just fine. 6.5 is plenty. Overkill, really.

The original question has been answered, but it raises another - why are servos so powerful these days? Obviously some of the claims will be false, but brands like Futaba and Sanwa should be pretty accurate.

I run the Savox 1258TG in my offroad racers because they're fast, super durable and relatively cheap. But they also have 14kg torque and I havent had an answer as to why thats necessary.

Like @markbt73 says, a s3003 works fine in a Monster Beetle

I am afraid that there is only one answer: everything which is bigger and more powerful is better. It ia hard to invent something new, so it seems this is only way to release new products.

This thread is from July, but...

Yeah, some of the specs out there are a bit optimistic,  but the minimum spec I look for in a servo these days, is metal gears, as I then don't need to use the sloppy tamiya servo saver, being from the bygone weak plastic geared servo era.

This was a vid I did, as the Novafox servo I fitted (alturn race servo) has similar,  if not slightly better specs, than the brushless futaba servo in the Schumacher KF2...🤔
