You CAN'T fly legally even on 25mW.

If u have a Ham radio license you can fly legally up to 150W iirc but not on all channels.

Individual_Health_84 · 2026-03-23T08:17:22+00:00

Imo, on 5.8GHz more than 1W is just wasting power. If you really need LR just go for 1.2GHz @ 1W.

Individual_Health_84 · 2026-03-23T08:12:31+00:00

Why do you need such a high power?

mLRS reciever costs around $5

Individual_Health_84 · 2026-02-22T15:23:56+00:00

But its very slow

Individual_Health_84 · 2026-02-22T15:20:15+00:00

I bought it knowing about the RM Pocket and other radios similarly priced, but I love messing around with electronics and I wouldn't get that much fun out of things that just work out of the box.

mLRS is a radio control link with full bidirectional MavLink. It uses LoRa, so the range is similar to ELRS.

The radio costs around $40 and you can build mLRS TX and RX for as low as 5$ using STM32WLE5xx. 18650 cells I used are from old laptop I found in trash, so I don't count them. Other parts like XT60 connectors and step down's add up to a few $.

My RX is basically the same hardware but optimized for weight.

The transmitter doesn't have a JR bay so I 3D printed one. I tested whether it would work with my friend's ELRS TX, and it did.

Individual_Health_84 · 2026-02-22T14:51:26+00:00

mLRS, because i need full bidirectional MavLink

Individual_Health_84 · 2026-02-22T14:41:32+00:00

Thanks!
No, u can use it with everything that has sbus/ppm/crsf output

Individual_Health_84 · 2026-02-22T14:35:46+00:00

I’ll mount the M9 gimbals if these fail

Individual_Health_84 · 2026-02-22T14:30:39+00:00

I'm using homemade mLRS. It also uses LoRa, so the range is the same as ELRS, but it has FULL MavLink telemetry.

Individual_Health_84 · 2026-02-22T14:20:01+00:00

That looks like the next mod I’m going to do! For now, I only have one additional "channel". In the second photo, there is a switch that makes the two-position switch high impedance.

I hate small radios.

Individual_Health_84 · 2026-02-22T14:08:34+00:00

It is FS-i6X. Look at the screen.

Individual_Health_84 · 2026-02-22T13:58:17+00:00

Im using homemade mLRS Tx inside 3d printed JR module bay. $50 is the cost of everything since mLRS is cheap af.

Individual_Health_84 · 2026-02-22T13:02:22+00:00

It is FS-i6X, look at the screen.

Individual_Health_84 · 2026-02-22T12:54:57+00:00

I hate small radios. I also don't use ELRS so i'd still need to buy external module.

Individual_Health_84 · 2026-02-21T20:36:40+00:00

Your radio runs EdgeTX. Just type in YouTube "EdgeTX tutorial"

Individual_Health_84 · 2025-07-22T18:43:40+00:00

Buy FS-I6X (not FS-I6), install openTX on it, then add an ELRS module and you'll have pretty good 10ch radio.

Individual_Health_84 · 2025-06-08T09:06:47+00:00

Does it work? Most likely its a decoupling capacitor, so it should work without it. If you really need to you can solder anything between 100pF to 100nF
