Default Need a servo same size as the old JR MN48 mini

This servo has been discontinued long ago and I need one this size. it is in between a mini and full size. Was really an odd servo. E-flite used them in a lot of their stuff and I picked up a Diamante a couple months ago that needs them in the wing.

If anyone has 4 they could let go of or any idea of another one this size that would be awesome.

they are
length 1.3" or 33mm
width 0.58" or 14.7mm
Height 1.02" or 25.9mm

So far nothing I have found comes close to this size.

Thanks in advance

Unhappy

So no one has any ideas about servos? That's a bummer

Hobby King / RC Timer / Banggood give dimensions of the servos and I have found them to be accurate.

TBH - rarely do I find servos that fit factory slots and often I end up adding ply plate to match servo. Modern servos have increased power / speed but shrunk in size compared to the old days ... so using a modern servo of similar size is often a lot more powerful etc.

I have considered doing that but the wing of this plane is so thin it needs the shallow servo to fit in the pocket and it is not hidden so adding ply frame it up to fit something else may look less than stellar. the rudder and elevator are not as big of an issue as they have more access room to use different types

I'll stay on the hunt looking for a pair of those dimensions.

Thanks

What about the ultra thin servos designed for thin wings ?

So far the only ones I can find are full size and too big. This was a thin mini servo. not full size but not micro either. Really an odd size, it's no wonder they quit making them

Would this work? https://hobbyking.com/en_us/corona-d...15sec-22g.html

I realize it's a little larger in one dimension, but slightly smaller in the other two, including being thinner. Can you make room?

That one is too small to fit the opening without adding additional framing. I actually have some of them.
