Don't worry too much about the servo failing Peter. I have buried servos in numerous models over the years and I can remember only one failing. I tend to use the best and most reliable servos that I can afford . I have models with buried servos on airbrakes, rudders and on the elevator of my Dart. Seven or so years on they still operate without a problem.

Looks like Brian's got immunity from Murphy's Law... :D

Also...7 years? That's still brand new!

Like Brian, I usually just bury wing servos. I rationalise my laziness by the argument that if you do have to cut your way in to replace one, the resulting patch is normally no more visible than a hatch would have been anyway, so why disfigure the aircraft with all those hatches beforehand? It does pay to take a few photos of the installation before covering it up though, so you can work out where to make the incision when the servo fails 20 years later!

Whichever way you do it, Murphy's law dictates that the servo will be out of production by the time it fails so you'll probably have to replace two of them and hack the mounting about - hatch or no hatch.

There you go then.
I think I will definitely go for the buried servos & smooth finish option, keeping a sharp scalpel handy in case of a problem.

Lower sheeting now in place - with spoiler servo buried!
Balsa LE strip has since been fitted together with aileron hinge area sheet.
Next job will be to complete sanding of the sheeting around the aileron before cutting this free.

No more progress yet I’m afraid as I have been diverted by the SG38 , PIK20 rebuild and other projects.
Hope to get back onto it soon though.

Yes I know the problem, I have just started building a bass guitar for my son which is receiving the attention and enthusiastic priority of my wife. I think modeling is on the back burner for a couple of weeks

Just got back to the SF33 build, so have started on the LH wing.
The build is pretty much as for the 1st wing & I am currently notching the ribs for the aileron spars.
Once the upper hinge spar spar glue has set, it will be time to cut notches for the top aileron LE spar.
