Plug the MPDX-1 into one channel of any PCM G3, PCM 1024 or FM receiver, and get eight in return — that's SEVEN MORE channels that a pilot can use any way he wishes. Unlike other channel expanders, all seven of the channels added with Futaba's MPDX-1 unit are fully proportional, switch-selectable — and all feature endpoint adjustment (ATV) and fail-safe! Very easy to set up; comes preset for PCM 2048 resolution.
Also works well with Futaba's R148DP and R149DP receivers; or use two MPDX-1 units with an R5014DPS and gain 14 proportional channels!
An inexpensive way to get the channel capabilities of a second radio!
Note that this unit will only work with the 14MZ and FX40.

The MPDX-1 connects to the receiver output of a 14MHz or FX-40 System and expands the signal of one channel to 8 channels. Servo operation of 8 channels is possible with 1 channel. Linear operation. Servo operation speed of each channel can be set. Fail-Safe for each channel can be set.
14MZ/FX40 can accommodate up to 2 multi-proportional decoders. Channel expansion up to 28 channels is possible with the R5014DPS receiver.
Operating control setting, direction of operation change, and travel adjustments are possible for each multi-prop expanded channel.

A 4.8V or 6.0V battery and switch.
