YC,
Often, lousy, under-sized, unreliable connections give the appearance of glitching due
to RF presence. This is especially true when common ground and power leads are shared.
You can eliminate much if not all of the inductive RF coupling between the transmitter
antenna and the long servo leads by a uniform, continuous twist the of the long servo
lead runs.
The addition of attenuation capacitors between the signal lead and ground can also
work, if the proper value is used. The potential "downside" of this technique is
altering the servo pulse rise time and fall time. Toroids can also be used if the
correct material for the toroid core is selected, but their size can cause problems
trying to fit them in servo pockets and other tight areas. Optical couple is not worth
the trouble and is not necessary.
If you don't want to hassle with the wiring issues, I have complete, "plug and play"
harnesses for the Pike, complete from the receiver to the wing servos, in stock.
John, thanks for the kind words. There will be a "little something" in your check at
the end of the month ;-)
Now I'm off to the shed to sharpen my skeg......hi ho, hi ho......
