Which 2 outlets are free in the CP Pro receiver? Is it 5 & 6? Trouble is, I was replacing my fried 3 in 1 when the phone rang. Having a senior moment. I couldn't remember where the bottom most connector was plugged in (I removed it to get it out of the way of the 3 in 1 wires) Is it in the (ascending order) ch5, ch6, or the B channel plug?

Even a good pic of the assembled receiver will do...

not sure myself, but you really can't hurt anything unless you plug it in backwards, just plug it in and test.

I think Battery is left open, matter of fact I'm pretty sure of it. This is the easy way to change Transmitter modes.
but anyways, yeah just do one at a time, plug in motor and push throttle stick, does it go? Great move to the next cable. Does it move, nope ok move to another channel.

Luckily for you there's only 6 channels Should go pretty quick.

I'm worried about frying something else? Do you have a CP Pro you can look at
?

Did you try E-flite's website for the manual?

Also you won't fry anything, promise. Just don't plug in the battery connector.

All of the channels can be in use, they all do the same stuff, power/ground/signal. Like I said unless you plug in the signal to the power you should be fine.

Channel 5 though I think is for the gyro. That's the turny device on the upper right side by the idle switch. Which you get if you install an external gyro.

I checked out my manual, and in the section for the gyro/brushless mot. upgrades, it shows the B ch without a plug in it....it works now.

Yep that's what I thought, I have a DX7 and the AR6100 so I couldn't quite remember been a month or so but I knew in the BL or Gyro section it had a picture.

channel 5 and the B or battery channel are the empty ones =)
