RadioMaster ER5A V2 2.4GHz 5CH ExpressLRS PWM Receiver - Fly Further, Smarter

Ready to ditch sketchy signals and embrace the future of RC control? Meet the RadioMaster ER5A V2 , a 5-channel PWM receiver built on the game-changing ExpressLRS system . If you're hunting for a reliable ELRS PWM receiver with incredible range, lightning-fast response, and solid reliability for your RC aircraft, your search altitude just hit cruising level. This little marvel brings the power of ExpressLRS to your fixed-wing planes, gliders, or any model needing standard PWM servo outputs.

Forget range anxiety; the ER5A V2 boasts the legendary long-range performance ExpressLRS is known for. Plus, it features built-in telemetry for receiver voltage AND external battery voltage (up to 35V, detected automatically!), so you know exactly how your power system is doing without guesswork. Setup is a breeze with Wi-Fi updates and a straightforward WebUI configuration. Stop blaming lag - it's time for control that feels truly connected.

  • ExpressLRS Powerhouse: Built on the high-performance, open-source ELRS firmware for superior range, low latency, and reliability.
  • 5 PWM Channels: Standard servo outputs for straightforward aircraft setup (ailerons, elevator, throttle, rudder, gear/flaps).
  • Smart Telemetry: Automatically detects and reports receiver voltage (Rx V) and main battery/BEC voltage (Tx V) back to your compatible ELRS transmitter.
  • Rock-Solid Signal: Features a built-in TCXO (Temperature Compensated Crystal Oscillator) ensuring stable performance even when temperatures fluctuate. Less drift, more dependable flying!
  • Easy Updates & Config: Supports Wi-Fi firmware updates and WebUI configuration - no complex tools needed for basic setup.

Do not buy
Color: Green/Black
Do not buy. When I received the watch it did not work and the battery was dead. I bought a new battery and it killed that one as well after about a month.

Inexpensive doesn’t mean cheap.
Color: Black/Orange
After 10 months, zero complaints. Well, I got rid of the horrible NATO strap 🙄. That’s a personal preference. Easy to swap out to whatever you like. Keeps accurate time meaning it’s the same time. I’m not micro analyzing it and the seconds gained/lost. It has a confident look and feel and makes you feel good when wearing it. Sure it’s not high priced but it’s not cheap. Very comfortable, light and not unincumbered. If this is what you’re looking at, you’d be satisfied. Great looking, durable and simple watch. Full confidence.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.

Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.
