Vintage Kyosho servo specs

[BattleTrak]

I have some old Kyosho servos that I am lining up for restorations. KS-88a, KS-88b, KS-91 & KS-100 (late 80’s-early 90’s) ..and can’t find specs for them. Checked the servodatabase, the Pulsar manual, Kyosho catalogs.. I DID find specs for the “KS-88” in the Pulsar Pro 2000 feature in the August 1987 issue of RCCA, but that’s it. Any other info would be appreciated!

I found this

Actually already figured out what this servo is but figured I'd add to Google's database so the next guy that searches the internet gets better info on it than I did.

Googling based on the KS-91 model number vaguely suggests this is a Kyosho servo but no specs or official reference can be found anywhere for a Kyosho KS-91 servo.

After opening the servo up I know why...the branding on the chip and serial numbers on all the parts reveal this "Kyosho" KS-91 is a re-branded Hitec HS-300.

I have a complete Pulsar setup.... Way back when, I got the Duratrax BB conversions for the servos....
