Wet servos?

[Lucam]

Hi,
I've got a foamie RC airplane model and I wish to add pontoons for convert it into a seaplane.
I would like to add a marine rudder, operate by a submicro servo; for simplicity (the pontoons will be removable) I'm thinking to put the servo on one of the two pontoons. One option is to put all servo INSIDE the float structure, letting just control wire to become wet in wather, but it looks pretty complicated; the other solution is to let the servo arm out the float, but in this way of course it will get wet during take off and landing.

I'm sure you boat enthusiasts knows a lot about wet servos, :D and could tell me if it will be so tremendous if a servo get wet... Fresh wather, by the way!

Thanks a lot for any answer.

It is only as traumatic as you make it. ;)

Wow, It Helps A Lot! :d

A Foam airplane won't need a servo to turn the plane, It's rudder will do the job. On a larger plane, some do hook up linkage to a water rudder but you won't need it. How's this for less hassle?

Cable operation from the rudder servo (inside the fuse) would be best for several reasons.
1) No additional electrics needed.
2) Anything added to floats (internal or external) only adds weight.
3) Any type of additional servo setup on or in a float will still have the possibility of taking on water. (A float filled with water don't "float" so good.) (As a side note, unless you add the same amount of weight to the other float, things can get a bit spooky.)
