RadioMaster ER8 2.4GHz ELRS 8-Channel PWM Receiver - Fixed Wing Optimized

Take control of your fixed-wing aircraft with the RadioMaster ER8, a feature-packed 8-channel PWM receiver built on the revolutionary ExpressLRS system! Specially designed for fixed-wing pilots, the ER8 offers the simplicity of direct servo connections combined with the incredible range, reliability, and low-latency performance of ELRS.

Stop messing with complex converters or flight controllers for basic setups. The ER8 provides 8 standard PWM output channels , making it ideal for gliders, sport planes, and any model requiring multiple direct servo controls. Experience the robust link quality that ExpressLRS (ELRS) is famous for, giving you confidence even at extended distances.

Beyond control, the ER8 delivers crucial flight information. It features built-in receiver voltage telemetry and flight battery voltage telemetry (up to 35V), automatically detecting the connected power source to send vital data back to your compatible ELRS transmitter. Know your battery status in real-time!

With its dual-antenna design and telemetry output power of up to 100mW (adjustable via LUA script), the ER8 ensures a strong signal connection both ways. The included high-sensitivity antennas maximize range potential. For future expansion, a 4-pin CRSF input port is available to add external telemetry sensors. Housed in a durable, one-piece molded shell, the ER8 is built to withstand the demands of regular flying.

If you're looking for a reliable, long-range 8-channel PWM receiver specifically tailored for fixed-wing aircraft using the ExpressLRS protocol , the RadioMaster ER8 is the perfect solution.

Quality Design
Color: Gray
Excellent frother/mixer Pros: - Quality feels premium. - Plenty of power to mix even with a drink packed with ice and peanut butter. Basically a mini handheld mixer. - Ease of use is great. I appreciated that this had a longer brother so I can mix drinks in taller cups. Also the grip is fantastic and it is easy very easy to change the speed with just one hand so you can hold the drink with the other. Longevity - So far it's been holding up and hasn't needed a battery replacement. Cons: None so far.

Highly recommend!
Color: Gray
Love this frother!!! Purchased to replace an Aerolatte that stopped working after a reasonable period of use. Right out of the box, it was charged and ready to go. I’ve been using it daily for about 5 weeks on the same charge it had on arrival and it’s still going strong. Love the variable speed and easy to work with one hand. And this baby can froth! It froths far better than our old Aerolatte. Also love the rechargeable feature so no more AA batteries wasted. This handy kitchen tool makes my morning coffee a true highlight. Highly recommend the Maestri milk frother!

Best Frother Ever!
Color: Black
Great little frother and very powerful after just one charge. I haven’t charged it since the first day and it is still going strong after 3 weeks. I use it daily for coffee froth, but have used it for mixing other things as well. It works great on mixing drink powders into water and for making salad dressing from scratch. It’s one of the best things I’ve purchased on Amazon for kitchen tools. My old frother ate through batteries and was 1/10th as powerful. This one really is amazing. Great quality heavy duty but still small machine. Extra attachment heads are also a bonus.

Very good frother that gets the job done extreamly well
Color: White
I hvae used this frother primarily for smoothies and coffees. Each time, it does a wonderful job. Deducted a star for the location of the speed control which is ontop of the device. It's akward to use one handed while attempting to control the speed, athough it's advertised as making it easier. It's not!

Good quality
Color: Black
Have used the frother 5 days in a row. It comes already charged. Fingers crossed no issues when I eventually have to charge it. I love everything about it. It’s worth a little bit of extra money as you can control the blending power from slow to fast. Easily held with both hands to coordinate. Today for a change I elected to just add a touch of bourbon caramel syrup to my oat milk -an excellent choice! They give you two attachments which is helpful. I’m not hard on my kitchen appliances but it’s good to know I have an immediate back up if needed. I rinse frother attachment out immediately in a cup of warm water and air dry on a towel. At this point, I highly recommend. My next adventure in the kitchen will be Matcha tea. I will use the bamboo whisk for the actual tea. If I decide to add oat milk to the top,(such as for a cold latte) I will use this frother.
