RE: Micro Receiver
The Electron 6 is a full range Rx that is an excellent performer. I think I have eleven or twelve of them in a wide variety of aircraft.
If yours is a negative shift version then it will work with your Futaba and in my opinion it will work better than some old standby Futaba offerings.
Heed the Hitec crystals only in a Hitec Rx. This is sop for any brand and Should never be deviated from. It may work for you however you just made yourself the test pilot, good luck and performance/range reductions are hard for the end user to detect. Crystals are ordered from manufacturers custom cut to the electrical characteristics of their product and no they are not always cut the same.
The Electron 6 comes with two tiny rubber bands in a packet that are to be slipped over the crystal per the drawing, do not omit these.
