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)

Does this require a bec in a stock trx4 sport on 3s?

Hi,
No, this will not require a BEC for operation.

Would this be a direct fit into the V4 Kraton 6s? If so, will it accept the stock mounting hardware/horn?

Yes, this servo should be a direct fit without issue.

Would this work well in a 1/8 arrma kraton?

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

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.
