Have you had a chance to test these servos? I'm interested in their linearity. I recently installed some JR 3711HV servos on elevators and found they didn't track that well after setting the sub trim and end points. This can be mixed out but it would be nice to get servos that tracked. I also have heard from a knowledgeable source that there is an inherent latency using this technology. Not sure why that would be.
I havent received these servos yet to test. They should be here in about two weeks.
The one I did see was very fast to center, but as far as how it trims after setting the end points has yet to be seen.
The HV brushless servo I tested trimmed fine after setting center. You can see it in the video.
I guess I should have set some end points too........
These are a standard size servo so not sure if they will fit in the stab of your plane, unless it a giant scale.
Here is the link to the mini...but it's not brushless.
But these are one of the better HV mini they make:
