I have a DX7 and i pluged the nicd battery by mistake into channel 7 on the receiver. Did i burn somthin up in the receiver. I dont use the channel but hope i didnt hurt the receiver or any thing.

any body else ever do this????

Also i have a Align Gyro 500X and i dont know which way to put the servo wire, it will plug in both ways. will i mess somthin up if i just try it?

Any help

Thanks

You probably haven't hurt the RX by plugging the battery in there.

As for the gyro, one of the wires will be black. That's the ground or - wire. On the gain lead, that has only one wire, that's the signal, which goes at the opposite end to the ground.

In general, most of this stuff is pretty robust against being plugged in the wrong way... but don't tempt fate, double check before you do things. Black or brown wires are always negative, so you can tell by that.

I recently also pluged in the extra battery into the wrong slot on my DX7 reciever and that chanel stopped working. I got scarred because I couldn't get that chanel to no longer work. I unpluged some of the wires and then plugged in the extra battery in the battery slot, and wala, it worked again.. thank God....

So, you should probably be ok...

On all receivers the power is connected to all servo outputs and the battery input. Some receivers don't even have a seperate battery connection, making use of the power pins on a servo channel. Don't worry about it.

If you're putting this RX into an electric Heli then you'll not be using the RX battery anyway. The speed control takes power from the flight battery and feeds it to the RX via chan 3 (throttle).

Gyro wire. You should have two plugs on the gyro, one with 3 wires, one with a single wire. The 3 wire plug goes in the rudder chan (usually chan 4) and the single wire plug usualy goes in chan5. This one controls the gyro gain remotely.

So which way around does the plug go? Well servos (and gyros) require 3 things, a 0v (ground), +5v (sometimes +6v) and a control signal. The +5v power is the centre pin in the plug, so which ever way around you connect it you'll not put power in the wrong place. The outer two are therefore ground and signal. connecting a plug the wrong way around will simply short the servo (or gyro) signal input to 0v, or in simple terms, no signal. You'll not hurt it by doing this, it simply won't do anything.

The 0v (ground) wire is normaly black or brown (or the darkest colour). the signal wire is white or yellow. The plug with just one wire is an extra signal input to the gyro, so plug it in the same way as the other connections.

Thanks.... great info!

so when u plug the servo wire(only one) into the gyro, i tried both ways one work one way didnt. so im all good, i think?

Thanks again for the info.......someday i will fly!!!!!!!!!!!
