RE: 1/4 servo
What type boat are you trying to turn? There are several standard size servos that produce considerable torque - the Futaba S-9202 on a 5-cell pack delivers 99 oz.in. Any Futaba servo will plug into your receiver. A standard Futaba S-3104 1/4 Scale servo delivers 132 oz.in. on a 4 cell pack and sells for $28.00 from Tower Hobbies.

RE: 1/4 servo
Today's servos are smaller and more powerful than they were just a few years ago. One with 100 oz. in. of torque should turn that rudder with no sweat. I've turned .21 outboards with standard servos and that's a lot of weight to swing.
That rudder is awfully close to the prop. Are you having any issues yet with it being so close?
The turn fins should be a little further out also as it looks like someone used 2 left side turn fins on it.

RE: 1/4 servo
i did use the same turn fins but i offset one to compensate.what clues would tell me the rudder is too close.this is my first boat and i am open to any suggestions.at first the boat didnt want to turn left.then i put the control rod towards the inside of the rudder horn(i guess thats what you call that)and i dont think the servo had the guts to push it under power.i think a bigger servo would involve changing the radio box.im not real excited about that route but if a stronger standard servo and relocation of the hardware would help thats a comparably easy fix.i have got this thing so it really screams in a straight line.im no gps or physics major but in my uneducated guess its pushing 50.id really like to be able to turn it.the chase boat is getting a work out

That's a much better shot! The rudder distance from the strut looks OK in that shot, the other one made it look closer.
Back to where we were. You'll find that your radio box might be a little tight to squeeze a 1/4 scale servo into but a high-torque standard sized servo would be a bolt-in most of the time plus a lot lighter.
This site has been a pain lately for uploading pictures as even mine already in my gallery aren't showing up on my 'puter. I just uploaded one shot on another thread and had to get it from another site just to post it! It could be this slow dial-up that I'm still using. I really need to upgrade!

RE: 1/4 servo
I don't know what you're presently for a radio system so right now that's the last of your problems.
I don't have my Futaba catalog handy right now but I've been using Hitec servos in most of my boats and I have almost every brand of radio system. Most will give dimensions so you can look at what you have and compare a heavier one torque-wise to see how it will fit in there.

I use it for all my cars/boats. Many functions and it is a high Quality Futaba FM radio.
