Great crawler servoReview by nicholas

I have this servo in my Capra. It is linked with the hobbystar servo arm. It’s been 6 months and this is a very good servo. I put it through the paces jamming tires between rocks, maneuvering with just the torque of the servo. Very under rated as all hobbystar electronics are. (Posted on 3/12/2021)
Great servo for MT'sReview by olds97_lss

I've been running 2 of these servos for about a year. One in my e-revo 2.0 and one in my outcast 6S. They have tons of power and are plenty fast at 6V. I run mine off max6 esc's at 7.2V so they are even stronger/faster. They center well and seem to work well in general.

I was lucky enough to get one of them on sale for $35 shipped. The other I bought after my savox 1210 died ($80 servo after a year) in my outcast and I needed a good replacement.

I have a comparison video of it here when I installed one in my revo:

I show it on 6V and 7.2V in the truck. (Posted on 3/1/2021)

Purchased this servo for my axial wraith and I’ve got to say it’s awesome. If you want a really nice servo for your rock crawler look no further. (Posted on 11/7/2020)

Would this be a direct fit into the V4 Kraton 6s? If so, will it accept the stock mounting hardware/horn?
A:
Yes, this servo should be a direct fit without issue.

Would this work well in a 1/8 arrma kraton?
A:
This should work very well in your Kraton and provide nearly twice the torque as the stock unit.

how would this servo be for an 1/8 scale e buggy? thanks
A:
It definitely has enough torque, but may fall short of the speed you want to see out of an 1/8 scale buggy servo. Here is a link to what I would recommend for an 1/8 buggy.
