1/72 Gato 2.5" Sub Driver; Recommended Servos?

[wlambing]

I am engaged in building a 1/72 Gato. I had installed some servos that nicely fit the tray fore & aft, side to side. They're too frickin' tall!! I have used Futaba S3110 and S3114 units in the past (S3110s in my Type 23). Is there a recommended make and model of servo to cover the 4 functions this boat will use?? If you had a good running boat, what did you use?

TIA,

Bill

Thank You! I'll check the fit dimensionally and proceed from there. :)

Servos are ordered up. Meanwhile, I'm doing stuff to further progress. Throwing paint around, test fitting bits and pieces, researching sail mods, etc. When I get the new servos, what hole in each servo arm gets the pushrod? I will use bow planes, bow planes retract, stern planes, and of course, rudder. I ask as I know these small servos have dainty arms and I don't want to wreck them by experimenting, if the correct answer is known.

Take care, TIA,

Cut the servo horns back to retain only the three holes from the center -- you need to do this so the horn does not strike the inside of the cylinder during full-throw. Experiment with what gives at least a 30-degree throw of the control surface with full-through (end-points set at 100%-100%) of the servo. Fine tune at the transmitter -- the end-point adjustment, if you have that feature.

I've found the second hole from the center (dirty-boy... get your mind out of the gutter you nasty old Auxilleryman, you!) to be the most useful.

Ok! What is the preferred assignment of servos? From left to right, looking at the shaft coupling sticking out of the end-cap. I originally was gonna go bow planes, bow planes retract, rudder, stern planes. Now, I think; rudder, bow planes, BPR, stern planes. I'm also going with servo arms facing inboard all the way around.

Rudder, port; bow planes, center; stern planes, starboard.
