EdgeTx has nothing to do with it, the max. transmit power is determined by two things, firstly the hw type, i.e. the type of specific tx module and the ELRS firmware loaded in it. So once again, just buy the Boxer ELRS TX internal module with its accessories and mount and connect it in the Pocket. It will work immediately. You can update ELRS later to get the latest version of ELRS.

Well the Speedybee v3 developed a fault when the sad card was installed so I swapped it out for a f405v4 with the 55amp Esc ( fancy heat sink)
I have flashed the Esc to bluejay and now has a fancy Dixy horn sound on startup, this was done as I was going to go with inav but decided to get another gps with a compass ( now inav doesn’t need one ) so for now I’m still playing with Betaflight.
I have removed the 100mw limit on my elrs and don’t think I will need anything more than the 250 I have at the moment.
I’m slowly starting to venture further away and I have reached the limit of my current fpv setup ( 2km)so it time to start planning on upgrades.
I was disappointed with the range of the current components (mismatched and not designed for the task at hand) so this time I am asking for a wee bit of advice!

I think I’m going to go with the foxteer 2.5w…. I already have two RHCP Speedybee clover which are 2.9 db gain so I think I will keep the one on the drone
I was using an old eachine screen that isn’t diversity which is probably 8-10 years old with another cloverleaf fitted and I feel that it is my weak link…… so it’s time for goggles….
Just need to decide on a set and pull the trigger.
Any recommendations? For a half decent set that doesn’t cost the earth? 
And is the 2.5w VTX a good buy? Or should I just go big and get the 5w version?
My goal is 5 miles out…..

So on the goggles you need a helical antenna. Probably with 5-7 turns. You can make one if you are adventurous or you can buy them, but they tend to be expensive. Secondly you probably want to look into a diversity video receiver, with dual helicals. If you get a set of EV800D, you could look at the PRO58, but it requires some DIY and soldering. Alternatively get a better set of goggles, Skyzone Cobra X maybe, it already does diversity, but hard to come by at the minute over here.

Sounds like you’re making progress, but are ready for some directional antennas. I never use Omni antennas on my goggles, they’re a waste of energy since my quad is never behind me.

I’ve been running DIY helicals for years, tried other antennas but always come back to these. They’re cheap too and easy to make, and have excellent performance.

I’ve flown over 4km using only a 25mW VTX. Here’s a DIY video I made years ago to show how cheap and easily they can be made.


If you browse my channel you’ll see years later I still use helicals on all my setups; HDZero, WalkSnail & most recently DJI setups.
At some point you’ll need some bigger batteries! Happy to answer questions, cheers!

GiantAntCowboy is right about the batteries. If you are going to be looking at the sort of range you are talking about, Li-ion is where it's at. If you want to make your own packs, a spot welder would be a wise DIY project or you can buy them from UMT, but given your engineering background you will find many tutorials on how to convert the PSU from a microwave into a spot welder. Pack size wise, if you are doing 5S or 6S, then maybe start with a 1P pack and as your range increases look into making 2P or maybe even 3P packs. As to 18650 or 21700, it depends. I watched, I think Ken Heron talking about it the other week and his preference was a 18650 (size and weight), but you can get both sizes from https://nubattery.co.uk/ for pretty cheap prices, so feel free to experiment. I think they both have different usage cases. I think 21700 could be better suited to a 6S1P pack with more capacity using say the Samsung 50S (5Ah, 35A continuous discharge, 390g) and 18650 for the 6S2P packs. But it's down to experimentation. Find what you like.

If not well all the FPV shops sell packs and I think CNHL do as well. Personally I would never buy a prebuilt pack. For me it's like the brakes on my motorbike, I don't want them to fail due to someone assembling them wrong, so i do them myself. I would rather build and test packs I made myself using known components and techniques.

Strangely, the pocket gets signal faster than my boxer. Stranger still, my T20 gets super-fast connection similar to TBS Tracer. I can plug the battery in, put the quad on the ground and have connection before I can put my goggs on. Boxer I am still waiting. Not long. but not fast.

What packet rate do you have setup on your Boxer module and what is the init packet rate on the receiver. If those two packet rates match the connection is fairly instant. Depending on which one has a different packet rate the receiver has to search up and down all the rates before binding. Thus takes a few seconds longer.
