Hi,
Does any one know what has to be done to a standard Futaba Servo 148 to give it more movement to use as a sail servo.?

your talking about [link=http://www.servocity.com/html/s148_standard_precision.html]this servo?[/link]

if so what size boat are you putting it on?

Hi Schmism,
Its 40" long is a Germany Optimist ?

Is far as I remember, it think it can be modified by removing/adjusting the potentiometer inside the servo BUT! I'm pretty sure that this servo does not have the strength to pull the sails on a 40" yacht. You're talking about a standard, 13-in-a-dozen cheap servo that comes standard in the box when you buy a new transmitter. There good for 1/10 scale cars, and small planes (trainers etc) and eventually as rudder servo in smaller boats. Anything else is way more than they can handle....

It might work at first sight, until you're actually sailing and there's a gust of wind, it could actually rip all the gears inside (remember, the standard 148 futaba servo is all plastic gears!)

Dazzler BE,
Yes I have since realised that the 148 will not be big enough so I have now gone to a 1/4 Scale Servo
which is way above what I need.
I have infact now been given the proceedure for the modification, so its just a case of doing it now.
Thanks for your help !

i didnt want to post that, that servo wasnt going to work so dont bother trying to modify it till i new what size boat you were putting it on... but you know that now

schmism,
I have already modified it as I want a 148 for single flaps on my Sunderland I'm building.
which needed more movement, so that all worked out OK
