Jumper T-pro JP4in1 ELRS full tear-down review & Official 2pos arm button upgrade

-Jumper T-Pro: We have come a long way from the T-Lite but not that long, it's clearly an improvement with the bits the T-lite was missing and now we have a much better menu layout, battery setup, better shape that remains compact for carrying, available in multiple variants: JP4in1, ELRS internal 1000mW or ELRS external 500mW bundle, Crossfire bundle, or cheaper CC2500 option now available.
The two 18650 cells will last quite a while even lower capacity ones, you don't have to worry if you're a long range pilot, having the same battery setup as the T18 or TX16S, battery life will be enormous with this smaller radio.
You have all the features an options you could want from OpenTX or EdgeTX which are both supported, but only the internal ERLS variant comes with EdgeTX preinstalled and also an uSD card fitted.
The official 2 position Arm button upgrade is finally available but will require changing the back cover and everything on it, I'll have a short video with that when it arrives.
All in all it's an improvement over the T-lite, the two cells will provide plenty of battery life and power for an external RF module, very compact as it should be for this style of radio, an all you really need remote for on the move or your main one even, works fine with the IRC Ghost Lite module or external ELRS mini modules.

[@andrewbt87]

the ELRS version with an ELRS RX will have more range than the O3

[@JustInTime0525]

Is the arm button upgrade present on all new batches, or it needs to be installed separately?

[@andrewbt87]

you'll have to buy the back cover that has the 2 pos sw and change it on your remote
