Default hs 81 vs dymond d200

I have a dymond 40 size tigermoth. I had dymond d 200 servos in the wing and 1 of them went bad and I noticed that the hs 81 has the same torque specs as the d200.
I'm wondering if it would be ok as I hate to have to buy a mini servo.
The dymond is a tad bit bigger.
the tigermoth only has 2 ailerons but I have a st 45 on her.
In the past the d200 seemed to work fine.
I can't run standard servo's due to the small wing pocket

I had both types of servos in some electric planes. The HS81 does not deliver the centring I need. The D200 falls short in resolution and gear strength. Guess. I don't use them anymore.

The Hitec HS-85BB is about the same size as the HS81, but is a better servo. It does cost about Five Dollars more than a HS-81, but is well worth it.

It still offers the same disappointing Dead Band Width of 8usec. I would get the HS-5085MG if it has to be Hitec.
