You can flash this receiver over WiFi | HappyModel ExpressLRS 2.4 GHz

[@JoshuaBardwell]

People have reported that the screws holding the module into the happymodel case can tear out of the plastic from normal stress of inserting the pins. The case comes with a foam double-sided tape to hold the board down, which people report is useless and just pulls off. Some people use stronger 3M extreme mounting tape to hold the board down, in addition to the screws. If you do this, be aware the tape can rip components off a PCB, so don't go crazy using too much of it in case you ever need to remove the board.

[@leadfingers]

How to make the stock module box work consistently for 2.4ghz tx: cut down tx board mounting post by about half, install empty module box into radio, install Tx into module and radio pins, snug tx bolts, go send! Edit: I used this on the OG white nylon 3D printed case and it worked well.

[@Jaroneko]

The foam I got with mine isn't even thick enough to contact the board and the case at the same time...

[@BrandonBeans]

Roll up that foam tape and shove between pin header and module lid to hold the important part firmly in place. This is the accepted method of happymodel ES24TX assembly 😅

[@sebastiansombra]

You can try printing an alternative screwless cases like this one: www.thingiverse.com/thing:4880481

[@stephenmutch4034]

@@leadfingers Using the white module box (the one which does not have the ventilation fan top cover) I had to remove the plinth where the radio pins enter the case as well as cut the mounting lugs in half. Then use the screws to mount the board and throw away the pad. The pad is too thick and without the pad between the board and the back of the module ventilation and hence cooling is much better.

[@p.i.engineer398]

for the EP Rx, build & flash is a bit less steps. Power up, wait for fast flash, connect to wifi with your computer, hit - build and flash. It will build the firmware and flash it for you right inside of the configurator.

[@thedarkrs1]

Hey there Joshua, Just a tip, if you connect your PC to the RX/TX u are flashing, when u build, you can just click build and flash, and it will automatically build and flash the rx/tx. no need to open the website, no need to use your phone, saves a lot of steps.

[@sendorm]

Great review. I would like to suggest you to try edgetx with 500Hz. I am pretty sure you will be able to feel the difference. Flashing edgetx is the most straight thing ever. Just get the flasher and flash. It converts the eeprom automatically. All your models will still be there too. Just don't flash your sdcard. It just works.

[@WezleyVarty]

Just another FYI - 17:32 - Flip the RX over, and on the antenna side there's a silkscreen "RT5G", which is "rx, tx, 5v, GND" :) EDIT: only true for PP RX's - JB is correct, no silkscreen for EPs.

[@WezleyVarty]

Sorry - I'm actually wrong there. You have an EP, not a PP (chuckles). The PP's are the ones with the silkscreen.

[@jonnyphenomenon]

This is such a great tutorial video Joshua. I had to refer back to it again after getting a second TX module for my classroom radio. I've been a crossfire user for years, but I am an expresslrs convert now. The only things this video doesnt address is the complications one might encounter when they attempt to flash with methods OTHER than wifi. the wifi solution works flawlessly. Other options, not so much. Also, the latest version (as of today) of expresslrs firmware is version 2.0, (and configurator 1.3.2) and it has changed quite a bit since the last version. Regardless, all of the information in this video still applies.

[@RuderalisFPV]

Its hard figuring out which of your videos is the right one to watch. You have the one im looking for, but i find myself having to watch 5 or so until i find what im looking for, and that depends on how recent the firmware is anyways.

[@jamesceastep8874]

Joshua: I know you did not discuss the HappyModel EPW5 PWM receiver in this video, but I suspect you may know the answer to this question: The EPW5 Express LRS 3.4 ghz receiver has an extra PWM channel that fixed wing pilots will like & probably need to use. My problem as a newbie in transmitter setup is that I'm not sure how to make maximum use of channel 5, and I've been told that chanel 5 on this Rx can only handle two states (like enable on/off), but I think I read/viewed somewhere that its real purpose is to enable up to 5 flight controller modes using a switch (or set of switches on the TX16s) OR a slider potentiometer to select each of 5 different flight controller states. My question to you is, can this in fact be done, and could you show us how to set this up using the EPW5 & a transmitter with a slider potentiometer? Thanks! - Jim
