Help!
Corona rp4s1 - how do I lock it to a different channel?

I have a Corona RP4S1 synthesized RX for 72 mHz. It has been locked to a certain channel (another person used it before me) and now I would like to re-lock it to my own channel. How do I do this? When I turn on my TX and connect the battery, the RX does nothing (light does not blink or come on at all). I have pressed the button but nothing happens. Please help.

I just figured out the problem. I had my ESC connected upside-down. I didn't notice that the receiver has an odd polarity layout in which the negatives are in the center, so the connectors are not connected the same way on the same side. Strange!

This is potentially misleading!

The Corona uses the universal connector convention of red (positive) wire on the middle pin. What he means can be understood if you look at the picture in the manual:

http://agert.homelinux.org/blog/imag...4S1-manual.pdf

When plugging in the connectors, the negative (black or brown) pins are adjacent to one another. Rather than being an "odd polarity layout" this is the way it's done on all or most of the 4-channel receivers that use a flat connector arrangement (Berg, Fly Dream, FrSky, Corona, etc.). It's clearly marked on the receiver.
