Castor is my good friend that I do not welcome everywhere, though.
I built my Lil' Spee-Dee with its aileron servo sitting on the top of the wing center, where the 010 Tee Dee will spit a good stream of castor that, if enters the servo near its output shaft stem, will sooner or later kill the electronics inside, or stick the plastic gears together.

I cut the bottom corner of a plastic bottle originally containing textile rinser fluid , and fixed it with the servo arm screw such that its skirt hangs down below the servo output shaft housing. Streamlining the servo area a bit, it will hopefully divert castor laden exhaust gases from the vulnerable electronics, too..
Admittedly not comparable to the invention of dynamo, the repurposing idea may still help others protecting a servo placed right in the trail of oily exhaust streams.

Good idea Andreas, thanks.

I use silicone oiled o-rings for water proofing servo shafts. This also may be helpful.

Thanks, Levent, I assume you pull the O-ring on the shaft and push it down the stem to contact the housing, then add the servo arm on top?

Yes Andras, exactly.

I think that is a very good solution, András. After about a half dozen flights, ought to see how effective. It will at least stop the larger drops, and with the wind of flight diluting the Castor mist, what ever manages to bypass the shield, after a season of flights will be easy to clean up. Very Happy

Thanks Greorge, I wish I could finally maiden the Lil Spee-Dee and test it, but freezing weather so far has kept us in my man-cave...

Nice, Innovative solution Andras!!!…., Looks like it will deflect the spent oil up and over….Mostly been in my cave too due the cold and damp weather…… That’s OK though…. Getting some things ready to fly for better days!!

Thank you, Robert...I am just adding this and other decorations to a ptoyotype plane  I have no idea how will perform...I am reading modeling handbooks now when temperatures keep me inside, just to add some science to my instinctive builfing and flying..

"Admittedly not comparable to the invention of dynamo."

I don't know Andras......pretty close. Smile

But, servos have gotten so darn cheap (for the cheap ones that is) they are almost throw aways. My last order from China for five wasn't much more than a six pack of Pespi, and usually shipping is either $1.25 or free.

Yes Bob I know, but having a servo kaput mid-air will have more costly aftermath than just servo replacement, hence my concern

How true. Losing one of your beautiful creations to a five dollar servo makes no sense.

What a neat fix! Simple and looks like it'll do the job. Reminds me of a servo problem I had many moons ago.. I remember back in my younger days flying in the winter with my radio in a box lined with a old wool sweater to keep my hands from freezing, and then finding the next problem.. having the servo grease get so cold it got sluggish..I think I bought stronger servos or some such..sorry for the derail.

Thanks, Mich, yes, castor thickening inside a servo is one of my concerns, too..I also had some short-circuited somehow by the goo slowly accumulating and settling inside. I am not sure about the electric conductivity of castor, but it was enough to destroy its electronics.

This small bird of mine could have accommodated the aileron servo inside the fuselage by causing congestion there, let alone the more complex aileron pushrod mechanism and friction as a consequence.

The external pushrod system combined with the fishing line hinges I learnt from Robert resulted in an almost frictionless aileron and elevator activation, that helps elongate the charging interval and hence, increase the number of flights the 150mAh onboard battery caters for withot recharging.
