Hi All

What receivers will work with a Turnight 9x TX?. Full range models. The standard RX has that "heavy" aerial that has broken on me in a not so heavy arrival.

I replaced it with a standard aerial but no joy.

Can't tell if there is other damage to the RX. No physical damage. After soldering I ensured that the new aerial was not shorted.

I pulled apart the damaged aerial and it is a piece of brass tubing with a plug in one end soldered to the aerial. This is IMHO forms an open circuit stub. ie wave guide theory. Any comments?

My first question is my main concern and I would like to know what other folks are using in the way of receivers with the 9x tx

Thanks for any input.

Cheers jq

I only use the turnigy 8 channel ones from hobbyking. Had some problems with the 6 channel so just stuck with what works. If I order something from HK then I'll usually add a couple of them as they are usually around $9 each.

I and many others use these 6channel Rx's. Cheap and tiny. No problems. I have them in two airplanes.

also note that they have ppm out which even many expensive rx lack. the 3ch were my favorite but price has doubled and if i need 4ch the 6ch is next best thing.

Those were the ones I had a problem with. I use them in my smaller planes/foamies and seem to be ok. Just don't trust them after two different model crashes.

What does this mean? PPM out?

ppm stands for pulse position modulation and is a combined version of the servo and esc signals that only need 1 pin instead of many. not so much for planes but very useful for multicopters and uavs where bulky cables are a problem.

I know PPM as a signal enoding within the transmitter that is used ot transmit the information to the receiver. Are you saying you are tapping into the PPM stream for something new? Otherwise, plugging a servo into the receiver gives you access to the PPM stream for servo commands. Pretty much all receivers do that.

servos cannot use ppm. they need pwm which requires a separate pin for each signal. ppm is a combined version of the servo and esc signals that only need 1 pin instead of many. usually an mcu is what connects to ppm. google is your friend.

good tip: slide a drinking straw over the aerial and hot glue it to the receiver. this prevents it from ripping off in a crash.

Why ask? If there was an update it would have been posted and you would have read it. Nothing posted means no update. Pretty simple really.
