Improving servo transit time?

[Subarubrat]

I am using a vintage 2ch R/c system made by Cox in a vintage Cox plane for the purpose of having a pretty much original set up. I have a cox 182 built with full house including flaps and brakes and it is a blast but I wanted to go a little retro with this Centurion. The main problem is that the transit time is just so slow that it really impacts the quality of flying. I am looking for any input on how to decrease the time it takes for the servo to match stick input. I did get an improvement by increasing the pack by one cell but of course one cell is a reasonable increase but also the maximum that is reasonable. There was once an article from the early 80's that was posted online that included basics such as voltage increase, re-winding the motor and some more advanced methods. Of course nobody needs those tricks today. Anyone have any suggestions other than voltage and rewinding the motor with fewer turns?

IIRC those servos where made by sanwa (airtronics) and had the cheapest looking motors i've ever seen in a servo....sort of a flat open framed motor soldered directly to the PCB

only way i can imagine to quicken them is by swapping the motor to something more modern. much easier just to give in and use a modern servo

I'll second that. If you want "retro" performance, keep the retro gear. You will have retro performance, which unfortunately only lasted a few flights...

People will say the same thing about our gear 20~30 years from now. The gear then did work and worked well. I am only trying to improve on one shortcoming. I am looking at some coreless mtors out of some servos I have laying around as a possibility.

if you can find something that'll fit in the case then great, but that might be hard because of the motor's shape

why not just use a modern micro and the top of the old servo case to hide it??

You might be able to replace the electronics with FET based controllers.

Coreless motors do not like impacts, due to their fragile windings, they can be destroyed on crashes...
