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.

Rubberized fun for your little ones
Pattern Name: Animals
If your pet baby loves squeaky toys, then these are right for them. Value for the money. Soft rubber, durable squeaker, and they bounce like a ball. I should say a ball that ricochets off of anything it bounces off of. Loads of fun for the little dogos.

Essential Dog Toy in "Our World"
Pattern Name: Funny Faces
I have bought ~a dozen of these packs over the last 7 years. Began when our cocker was a puppy and (with puppy teeth) prone to destroying each squeaky toy he loved. Searched on something like "non-destructible (or maybe durable) small dog squeaky toys)" and these popped up. Now, they're Bark Park playtime essentials. SO many pups there love them (and we let the "stealers" keep them and tell their parents how to get them. Every day we have Bark Park squeaky egg symphonies (one mini Aussie plays 3 simultaneously--2 by mouth; another with his foot) and chases, as ALL the doggos love them. They last a long time and can be washed (I use a toothbrush and block the hole w. a finger).

perfect size
Pattern Name: Animals
these are the perfect " Goldilocks " size for our 3 month old frenchie! Not so big he cant bite them and squeak them and not to small where i worry they could slip & choke him. just a heads up the squeak is pretty loud lol they also are very soft both in texture and in terms of being able to squeeze. thy can bounce a bit which he loves too. the green one for some reason is thicker and harder for him to bite & squeak so he doesnt really play with that one. so far they are holding up to his puppy teeth but i suspect if you have a aggressive chewer they wouldnt do so good. very happy with the purchase. and as you can see in my video so is our little man lol

Indestructible for our 8 pound Mi-Ki
Pattern Name: Funny Faces
Our small dog loves these and he hasn't been able to chew them up. He loves their unpredictable bounce and chases them all day. He also likes to sleep surrounded by them.
