Does anyone know the specs for these spectrum servos?

Z270
Z590

I just purchased the DX3.0 it it came with these servos. I plan to use them in 8th scale onroad but I feel they wont be able to handle it. Am I wrong?

I cant seem to find any info on these servos on the spectrum site.

Any help would be appreciated.

Same servo's as the JR servo's except grey. Check here for the spec's.

+1. If you value that Ground Based Missle, use better servos. The 590 will get by as a throttle/brake servo for a while. I was under the impression that 1/8 onroad needed strong steering servos. Like in the 150oz.-in. range or higher? I don't know, I don't own a 1/8 on-road.

JR Z270
49 oz/in(6.0v)
.19 second transit (6.0v)

JR Z590
85 oz/in(6.0v)
.15 second transit (6.0v)

The 590 would probably work for throttle.
