I'd be more worried about the transmitter than the servos. I bought a Conquest 4 that is about the same age as the one you bought, mine being a 1986 purchase. The problem is that, back in 1991, the FCC changed the rules on how a transmitter could work and, unless your system was updated, it's probably illegal. Mine has what is known as a "wideband" transmission pattern, meaning the transmission pattern extends, IIRC, 80KHz above and below the frequency listed on the transmitter. When the FCC changed the rules, they required all transmitters to be retuned in order to extend only 40KHz above or below the listed frequency. If your system was upgraded to meet the new rules it should have a gold sticker on it, making it legal. If not, some if not most clubs probably won't let you use it
