Default Best servo 1/10 TC

Simply, I want the best servo for my 1/10 electric touring car.

I have set on an Ko Propo.

There are the RSx one10 Response and the BSx2 one10 Response.

The RSx have a coreless motor and the BSx a brushless.

The BSx cost more than the RSx.

Is it worth going for the BSx?

If you can afford it, yes.

Brushless motors are better full stop.

i really like the Sanwa SGR-BLS and SGR-BLS v2. this was my go-to servo until Awesomatix released their own servo!

Thanks for the answers.

The BSx2 one10 Response is quite new and I have read that some have problems with it.

Really wanting a brushless servo, counting out the RSx One 10, I bought the "old" well tested Futaba BLS551 instead.

The BLS551 is now replaces with a newer version (571 or something I guess), which is capable of running HV, but as I do not run HV in my touring car, the BLS551 will do fine.

I've got a 551. It's plenty fast/strong in a TC and takes a beating. Really good bit of gear.

Sadly superseded and the replacement 571 doesn't appear to do anything better apart from handling 7.4+V as you mentioned. I think it is a little cheaper though, so I guess that's a small win.

As far as I can determine, this is pointless in electric TC with current battery tech, we can't guarantee full 7.4V for a whole run (due to both peak draw and voltage drop), so performance of the servo would fluctuate.

Yes, agree. Wonder if you could power the reciever directly from the +/- on the esc and have some small capacitor/regulator in between to provide a (more or less) stable voltage.

On mylaps I can see that my receiver receives a constant voltage of 5,8V from the esc, and even though this is not even 6V, it is constant through out the entire run.

I've been really impressed with the Xpert 3401 low profile servos, so far. I have a lee martin edition and a full aluminum case version. They have some of the best specs and aren't very expensive. Fast, strong and precise, without drawing a ton of power.

I moved from ko to the sanwa bls v2 to allow the SHR functionality of the Exzes Z I bought. It's stunning, I've never had such a smooth and precise servo. Still have a soft spot for KO but can't see myselft changing this combo.
