The slight down side with the Megapoints system is that it controls 12 servos, ok if you have a lot of turnouts on one board but thats unlikely in O gauge. So you end up with either wasted channels or a lot of long inter-board connections for the servos which can sometimes be problematic with noise pickup causing the servos to twitch. I keep asking Dave to bring out a 4 channel version but it falls on deaf ears.
