Massimo Ursicino sells a six function Sidus F1C timer with RCDT as a standard feature.
Functions are operated by a single servo which is stepped to release levers. The levers are mounted in a neat Seelig-style NC machined face plate which also incorporates a ball race to take the loads imposed by them, which otherwise could damage the servo. The latter, like all RC servos, is designed for loads applied radially to the output disk. However, the forces applied by the levers act parallel to the shaft and so could potentially damage the servo if they were applied to it, hence the load carrying bearing in the faceplate.
This timer has a special pocket-sized control unit which doubles as the RCDT transmitter and uses an optical (IR) link for programming the timer.
Initial versions of this timer used 2S Li-poly batteries for both timer and control box and were supplied with a cell-balancing charger. Current versions use single cell Li-poly batteries for both units and are supplied with a simple two wire charger. The timer now incorporates a DC-DC converter with 5v regulated output to run the servo at optimum torque and speed.
There are a choice of available faceplates depending on whether you want one or two lines running forward from the timer. As an alternative he can supply a drop-in replacement for the Verbitsky/Babenko mechanical timer. This uses the existing levers on those models.
