Don’t just put any servo in there. Most standard servos provided with a Tx/ Rx kit
are “basic” and simply won’t handle the task required there and the effort from the
water on our IOM rudder. Only 1 meter long but nevertheless the pressure on the rudder
is still substantial. Well worth spending few bobs on a good servo. I decided to
write this article since I lost control of my TS2 in medium conditions after the
U-shape connector from the rudder rod to my Futaba S9202 snap clean. I did some research
since and this is my findings. Below I have listed my short list of, in my view,
the best servos able to do the job on our IOM boat. Hope this will help you in deciding
which is the one for you.

Digital
The digital micro processor is 10 times faster than an analog servo.
The standing torque of a digital servo is 3 times that of its analog counterpart.
Programmable for failsafe.
But typically higher power consumption than analog hence requiring more powerful batteries
Brushless
At least FIVE TIMES longer-lasting than brushed servos.
30% faster response times.
Greater resistance to jolts and vibration.
Smoother operation.
Same power consumption as brushed digital servos.
Same compact case size as standard servos.
Exceptionally durable geartrain.
Smooth dual ball bearings and strong Samarium Cobalt magnets.
Ball bearing avail as option
A good starter
Enough torque for our IOM and good speed
Great reliable servo used in a lot of IOM
A good upgrade on the 9202
Huge torque & quick enough servo
Same as its analog brother but digital
