Great looking little boat, David. Hope it runs well for you.

Got some info about the type XXIII
Ran her today without the ADF, running low speed no problems, higher speeds works also, but the too late correcting factor is a issue, once she breaks the surface airpockets become a problem.
Static CG is right in the middle of the tower, added weight around 500 gram, rear and front diveplanes work together on the same channel, no depthkeeper present.

MG90s are very worthwhile upgrade over SG90 servos. The difference in price is small, but the MG90s has metal gears with a finer pitch, so they run smooth and are torquier. Same footprint as the SG90, so a straight swap.

As always, good struff from you side of the Ocean, Andy. Already have a box-full of those. Great minds think alike, pal. Jake had me put those Ironman mini's in his big 1/48 NAUTILUS and they seem to be up to the high loads presented by the propeller pitching mechanism.

Back to the Chinese Type 92 SSBN and Italian CB.

I do. An almost completed 1/96 STURGEON. But, I have many obligations (I'm teaching regularly now) to address so I want to clear those off the table first. Still 'legacy building'. The Type-23 has been banished to upstairs storage, and the cylinder has been post missioned and socked away in the shop 'ready service' pooka under the heavy-duty bench.

No rest for the wicked. :)

It’s a beautiful boat and it’s too bad it’s giving you fits for several years.

Assuming the 'bad' servos are cheap China servos. How many of those are you replacing?

It varies from source-to-source, about 10-15% failure rate upon initial receipt (I used to buy them in bulk), testing was dynamic with a stall-load. Failure after installation, not so much. Usual point-of-failure was the feed-back potentiometer, which was the case with this unit.
