As a side note, my 1990 F3 PGM-II harness uses a 600mah NiCad battery, but the servo motor listed in the 1990 HRC manual is the NSR KV3 part number; nothing special. Even the NF5 uses a battery, so for the reason Fontyyy has given, I would be loathed to try and use a capacitor, proven by the fact I've had one in the shed since my mate gave it to me way back in 1998!
I can see your point Si, but I would take the NiCad (or possibly 3XV) route over a capacitor or no battery at all.
