Since no one seems to have answered, Telem Ratio is how often ELRS sends telemetry updates to the radio. You can have your radio tell you to land when the voltage matches a condition you setup. There are a couple of videos on how to do that. It's useful if you lose your OSD for some reason. I tend to use 1:64 or 1:32, which means 1 packet in every 64 packets will be a telemetry packet, or on 32, 1 in every 32 packets, etc. Most people don't need any more than 1:64 or 1:32. If you are getting Telemetry Lost errors, you can try a lower value, but I sometimes fly out to half a km and don't have issues on 1:64. Secondly, when running ELRS, I use the maximum power available, but switch on dynamic. Most of the time you don't need to output at 500mW or 1W. Dynamic. as I understand it, monitors LQ and RSSI and adjusts power output to achieve the best signal quality. So if you are flying in a big open field and fly 2km away, it may never use any more than 25mW. But if you flew behind several big concrete buildings and the LQ dropped out it would adjust the power to keep the link up. There is a way to monitor and log it on the radio and many people have said when you are flying complex environments like bando's, the power output might jump up to the max you set for a second to keep the LQ from dropping out. I run my radio at max power for that reason, but it doesn't output max power constantly in dynamic mode, only when it needs it.

I was struggling with it for hours, thank you for the Video. Im using the Jumper T-pro V2 4in1 with the Elrs module and it worked.

I so needed this. Thank you. Mine did not power up from either the battery or the computer and making sure I had everything connected as you did helped me out.

Good video tutorial. Most appreciated. Happy Holidays and level wings.

Thanks man, I just got that module and wasn't sure if I needed to buy anything extra to hook it up

Gracias por el video, pense que me había llegado fallado el modulo ELRS

Best video. So clear! Thanks a lot

Thank you for this tutorial.

really help me thank you

Great video very helpful for me thanks, got youself a subscriber. lol

Thank you so much !!

Hi mate, great video!!! A quick question... have you experienced any power issues on the AION module connected via the default bay adapter of the v1 tlite?

Great video man very helpful. I was wondering about the blue lanyard ring you have on the radio, how would I go about getting my radio to have one like that? It's exactly what I have been looking for, looks like it replaces the light.

I only get the option to flash, no build and no build and flash. It also just doesnt work at all

your radio jumper T-Lite v1 or v2 ??? T-lite v1 output voltage be matched with the module ???

What sort of range are you getting with this? Would be nice to use my tlite with my larger 915mhz builds instead of lugging the tx16s around haha

Is there a internal ELRS module for the T-lite that can replace the internal module the T-lite shipped with?

Hi have just updated my jumper from 2.5.0 to 3.0.0 I did it via wifi, it says success but the screen on the jumper no longer powers up.Would you have any ideas? your help is much appreciated.

Does it work for tbs tango 2 pro? Is it compatible any module bay add on? 🍻

I see jumper AION requires voltage 5-8V, but jumper t-lite only has 1 battery (4V). Can the module working properly with only using 1 battery (under voltage) on 500mw?

I try to connect aion tx to adafter jumper t lite but aion tx not on. How to modify port on adafter jumper t lite for aion tx match?

Can l add module to jumper t lite v1? If I can add myodule, how can I add it? Please help me!!!

but on the screen it shows me "no handset" could someone explain why this happens

I think I messed something up!!! Mine keeps rebooting! I can’t get it to turn on! Please help me

hey man, after watching ur vid, i couldn't find the USB serial device, but rather the USB modem for some reasons, and I didn't see it on urs. can you show how to find that on mac
