Default Good servo for 1/8 onroad??

Used to use Sanwa ERG-VZ, but it seems to be discontinued product. Looking for good servo's to my brand new MRX5-car. Any suggestions? Maybe I'm wrong but it looks likes that the new Sanwa servo's are not giving as good tech specs than the old ones (13kg/0.10sec). What would be the VZ replacement from the new ones?

Or would it still be wice to try to find a couple of VZ-servos and go with them?

I'm also amazed by the current Sanwa line of servo's.
They used to have servo's with speeds of around 0.06/0.07 seconds but now they all are around 0.10.
Even the supposed to be super fast SRG servo's are 0.10.
They claim the SRG technology makes them a lot faster but they don't give you any numbers on how much faster they are, plus I don't think this technology can make up for 0.03 seconds.

I'm currently looking at some Kopropo RSX servo's, super fast, a lot of power and you can connect them straight to a Lipo.
I only hope Kopropo will make a low profile version pretty soon.

Unless you want to pay top dollar for the very best, its actually hard to go wrong with this one.

If you are looking for indestructible, strong and cost effective than look no further than Hitec they have the new high voltage premium digital that can handle lipos without a regulator (you know everything is going to lipo)

Take a look at the
TH-7940 has a .06 speed on lipo
TH-7945 has a 300+ oz. in. of torque
Titanium gears !!

Although the new servos do not share the same specifications as the older ones but the overall response is actually quicker. That is if you are using the latest SRG servos with M11X & RX-451R. I would recommend SRG-BZ or SRG-CZ for steering and SRG-BR or SRG-CR for throttle. If you prefer Futaba, BLS-351 for steering and BLS-451 for throttle. The RSx from KOs and DS87xx from JRs are good but they charge a premium for their servos. I don't think you can go wrong with Sanwa SRG or Futaba BLS servos.

If you want to save a few bucks. SAVOX is a decent option.

The Savox SC-1258 is very snappy but it draws a bit more juice than the Futaba BLS servos.

I think the OP needs to give a price range first ,then people could give better input

Thanks for everybody. It's nice to see that I'm not alone thinking about these things...

The price range is somewhere in the VZ-SRG area. The RSX-level hurts a little bit too much. Second, you have to always remember that it's the total cost that counts. If something fails, (receiver, battery, throttle servo), I will loose the engine at the same time, in the worst case scenario...
