Servo Torque required?

[Basstronics]

Is there any way to know how much servo torque is required? Or is it just an educated guess?

I have a 12.5" BBY Micro Patriot that needs a stronger servo.

I have a 15" micro Hydro with the same issue.

Need more torque. Im unsure what either servo is torque wise. The Micro hydro has decent torque. The one I put into the MP I can turn easily...

Would 21 oz-in be enough?

I do not know what you have in there at the moment but I can strongly suggest one of these

I use one in my 26" rigger and 26" Canard with a lot of success
My small 13" cat has one but has not got wet yet.

My new rescue boat has two but neither are used for steering

I have two of these and they are great http://www.hobbycity.com/hobbycity/s...kg/19g/0.12sec

I ended up going with two of these:

I do alot of shopping at Hobby King, but I want it faster and not to pay $15 shipping...

So it worked out in the end.

21 Oz-In servo's. Best of all the exact size I need!
