Using a TD-MX Receiver in a Basic 4 Channel Plane

[@michaelladd9899]

You put out great information that is clear and concise have you tried messing around with any of the inav stuff that looks interesting as well

[@all_rc]

Not yet .. but yeah, I do want to play with that. If I do, I'll definitely put up a video

I designed a junction board and had 20 of them made by JLCPCB for less than $5. It has 6 pairs of 3 pins which provide 2 connections for up to 6 channels. It measures 20.5mm x 18.5mm and connects to my receivers using one 3-pin lead (channel 1) and one 5-pin lead (the signal wires for channels 2-6. It allows me to place the receiver ahead of the battery and run only 8 wires under the battery tray instead of 18. The dual throttle connections allow me to power everything from a separate BEC, if desired. I made a prototype using perfboard and used it in a 70mm E-flite Viper..

Great timing for your video as I'm researching the TDMx for a 3 channel wing set up(2 servos and a ESC) . What's the simplest way to go about doing this with a X20S radio?

[@all_rc]

Are you asking how to setup the mix? If so build a new model with 1 ail, 1 elevator, no rudder and no flaps. Take both elevator and aileron rates and make the weights 50٪. On the aileron mix, change the Chanel count to 2. Make output 2 ch2. On the elevator mix, change the Chanel count to 2. Make output 2 ch1. Reverse channels as needed. This is how I setup my Mirage 2000 which is a delta edf.

​@@all_rc thanks for that. I was talking about wiring the TD Mx for 2 servos. Mine should be arriving in a few days, I think it'll all make sense once I have both the receiver and the TrasMaTech . I couldn't quite get the wiring set-up.

[@all_rc]

Just wire the Outputs from the tdmx to the top of the trasmatech board starting with ground, power (V) then ch1, ch2, ch3, ch4 . If you don't need sbus or s.port, you are done. You only need 2 servo connectors, not the 3 I used. Both the TD MX and the Trasmatech are clearly labeled. If you have any issues, feel free to email me at [e-mail] and I'll be happy to help

Hello, a simple question about the TDMX... How many channels does it deliver via SBUS OUT at most...? 16 channels or 24 channels? Thanks you very much for your answer.

[@all_rc]

That depends on the sbus device you plug into it. All mine that i have used are only capable of 16ch but if the device you are hooking up to the receiver is capable of 24, it should work. I believe you have to change the sbus type in the receiver options to 24ch in order for it to work.

Would it be safe to use in my dlg glider?

[@all_rc]

It would be perfectly safe. However, the reciever, although very thin is kinda fat. It might be a bit fat for your thin bodied dlg. I would check the dimensions of the receiver against the space allocated for your receiver. Also, i assume your dlg is carbon fiber so you would want the antennas outside the body. The receiver has 3 antennas. 2 traditional 2.4ghz antennas and one 900mhz antenna. The 900mhz is a bit bulky for a dlg, especially outside the body. Frsky does make stone very narrow receivers specifically for gliders. They aren't dual frequency like the TD-MX but they might be better suited for a dlg. I run the Frsky GR6 receiver in my dlg. Very small and lightweight with a built in vario. If you compete then i assume you don't can't have a vario but is nice to have when just flying the dlg for fun. It's only 2.4ghz but it works very well.

Cool but why not just buy td r6?

[@all_rc]

Yep. I mentioned that in the video. Tdr6 at the time of the video was just brand new. I was using that system before the tdr6 was out and only the tdr10 and the tdmx was available. I posted the video for those like me that had quite a few tdmx receivers. I was planning on using the tdmx for redundancy on my big planes but found that the tandem receivers were so solid I stopped using them that way.
