Hobbyking release today a PPM Signal Mixer version B for
their Head-Movement-Tracker Gyro. This will help people with entry level Futaba transmitter to use the HT. Basically, from what I understand from the description, it adds channels to the ppm stream generated by your transmitter. If your transmitter has 6 channels, it becomes an 8-channel TX (you need a 8 channel receiver to really use it, of course).
From the website:
PPM Signal Mixer is specifically designed for those who own low end Futaba transmitters (such as the 6EX), allowing you to also use the
head movement tracking system. And even can be used with JR
transmitters. (soon available)
This version B is designed for 6EX
transmitter which comes with 8 channels receiver.
Just connect the PPM signal mixer inbetween the Advance Head-Movement-Tracker Gyro and the Transmitter and PPM signal
mixer will map new channels special for X-GYRO 1000 via the transmitter.
Then it maps 2 channels, and put them after the transmitter channels,
now it’s 7 CH and 8 CH, that ‘s why you need a 8CH receiver. Connect the
servos to 7CH and 8CH.
Note: Only works with Futaba transmitters.
Voltage Supply: 8V-12V
