Designed specifically for use with our Nexus Helicopter Flybarless control unit and compatible with all CRSF/S.BUS enabled flight controllers the RP3-H ExpressLRS receiver comes with a built-in TCXO and an integrated housing design that makes the receiver tougher and ready to mount in modern helicopter frames. With the RP3-H receiver, you can get reliable, stable, and accurate signal reception, which enhances your flight experience and allows for superior performance even in demanding environments. The RP3-H also features an Ext-V telemetry input for compatibility with older ESCs that do not provide battery voltage telemetry via the control unit.

The RP3-H receiver uses the Skyworks SKY66112 power amplifier to increase telemetry performance, the PA provides up to 100mw of telemetry power, and antenna switching for antenna diversity. It is developed around the ESP8285 MCU and SX1281IMLTRT RF Chip, offering Lora and FLRC 2.4GHz RF links that provide incredible range and low latency. With Wifi built-in, firmware updates can be done on your craft without the need to remove the receiver.

TCXO (temperature compensated crystal oscillator)

The TCXO ensures high stability and accuracy in frequency control, compensating for temperature variations. This results in consistent and reliable signal reception, even in extreme temperature conditions. It also reduces frequency drift over time, providing long-term frequency stability and preventing signal degradation. Click here to learn more about the TCXO.

A special thanks to the Rotorflight development team who without their hardwork and dedication this project would not have been possible. Learn more about Rotorflight HERE.

Just works for us!
Size: Size 1, Unit Count: 44
Had to transfer from Huggies and Pura because our son kept leaking through those, despite trying all the tips and tricks. Needless to say we’re really pleased with these! They’re WAY more absorbent. Only downside is that it’s not designed for sensitive skin, but diaper rash cream always does the trick for our little guy

Outstanding, top of the line diaper!
Size: Size 1, Unit Count: 252
We normally use Huggies Little Movers with our 3.5 year old (nothing against them, they're also great diapers) but recently decided to give Swaddlers a try, and will not be going back. This is a top-of-the-line diaper and excels in all ways. We use a size 7 though could *probably* get away with a size 6, and use about 4-5 diapers a day on average (not including his overnight diaper) depending on how much he's had to drink and how often he poops -usually once a day, but could be as many as 3 times, especially if he doesn't go one day. The first thing you notice about these diapers is how soft they are. I mean, they just feel like they would be comfortable on a child, and since they're in them practically 24/7, that's important. The diaper is mostly white, and the overall designs are more muted than a lot of other diapers, with "Shilo and Friends" -an elephant and duck - on the front and back. I personally wouldn't mind something bolder, I don't think my child cares or even notices. There is a wetness indicator that goes down the length of the diaper, front and back. Nice to have I suppose for a caregiver who maybe doesn't change a lot of diapers, but at this age and stage, it's easy to know and tell. Like all Pampers diapers, they are scented. I happen to love the gentle powder-like scent, but it's a turn-off to some who describe it as too strong, and of course, if your child is sensitive to that, you may want to avoid Pampers diapers. Inside, the top sheet liner keeps his skin dry, even when he wets heavily -which is usually - and does a good job of keeping poop from sticking to his bottom. The "blowout barrier" in the back also helps contain any messes. In terms of absorbency, I'm pretty amazed at how much they can hold. Being a little older, he tends to stay drier for longer periods and then pee a larger amount at one time, but the diaper almost always holds it in, and leaks are rare. The one thing I wish that Pampers did do was have wider tapes, like Huggies, at least on the larger sizes, where kids are more active. It hasn't been a problem, so I don't really have a reason for saying that, other than that it seems like it would help with fit, but it certainly won't keep me from buying or using them in the future.

History of Egypt
Format: Kindle
Egypt has played a vital role throughout history. This book traces and evaluates the history of Egypt from ancient times until the modern period. During ancient times, the Pharaohs created a strong Egypt. During the Ottoman times, Egypt played a significant role as a regional power. Both French and British played a vital role in Egyptian politics. The Suez canal put Egypt, an important player in world commerce. The Nasser regime entered Egypt into cold world politics. The USA managed under Sadat to place Egypt at the American camp. Eventually, Egypt was the first Arab country to sign a peace treaty with Israel after various brutal wars. Egyptian culture dominated western civilization throughout the centuries. The reader will enjoy this book.
