The NEXUS Flybarless (FBL) control unit has been designed from the ground up based on the Rotorflight 2.0 reference design. All aspects of the NEXUS have been planned and tested for optimum performance and compatibility, ensuring the best out-of-the-box Rotorflight experience on the market today. 

With its advanced STM32F722 MCU and the TDK ICM-42688-P 6-axis MEMS motion tracking device, which combines a 3-axis gyroscope and a 3-axis accelerometer, the NEXUS flight controller ensures precision control and flight. A large 128MB of onboard flash memory ensures you can log all your flights for fine-tuning and adjustment.

RadioMaster Plug'n'Play solder-free RP3-H ExpressLRS receivers feature a locking connector system to ensure a stable connection between the control unit and receiver. DSM and S.BUS ports are also available for use with your selected receiver type. The NEXUS also features multi-function ports for future expansion.

The NEXUS features a CNC machined aluminum case as standard, which looks great, protects the control unit, and dissipates heat for the F722 processor.

    I couldn’t put this book down!!
    Format: Paperback
    I couldn’t put this book down! My daughter & I stayed in a bed-n- breakfast in Lochcarran on our trip to Scotland right before the COVID pandemic. Not only is the story a fun cozy, whodunnit, but I could visualize the geography while reading. I love the Scottish Highlands & Dee describes them perfectly in this book. Can’t wait to read the next book..it should arrive today!!

    Good book
    Format: Audiobook
    Book was interesting but had a hard time with the Scottish accent. Plus I have hearing problems so that may have been part of the issue too.

    Pronunciation matters, and I can't finish this book.
    Format: Audiobook
    I listen almost exclusively to books set in Scotland & Ireland, so I'm very familiar with the accents and find them incredibly charming. That said, the name pronunciation really irritated me. The main character is Ally, but they are not pronouncing it to rhyme with Sally. It sounds more like they are separating it into two words- All E. After investing hours into the audiobook and trying to not let it bother me, they introduce an American character, Mamie, which should rhyme with "maybe", but NO- they call her Mommy! It is very confusing- I kept thinking a new character was introduced who was a parent. Nope. I give up. I don't think I can finish listening to this. I feel like I'm being pranked.

    Enjoyable Scottish-Flavored Cozy Mystery, Although Not a Hard Solve
    Format: Kindle
    Ally is a 60-something-year-old woman who upends her life in Edinburgh to move to tiny Locharran in the Scottish Highlands and open a B&B in the old malthouse located on the estate (like the rest of the town) of the Earl of Locharran, Hamish Sinclair. She has her first paying guests in an older, English couple, and an American, Wilbur Carrington, who is investigating his Scottish roots -- and possibly his being the rightful Earl of Locharran? Ally's cleaning lady finds Wilbur with a knife in his back outside the B&B. This is sure gonna' affect Ally's brand-new business! Of course, her kids back in Edinburgh are concerned for her safety as well. Along with the lecherous earl's attention to Ally, the murder at the local B&B makes Ally the intense focus of local gossip, so this spurs her into attempting to solve the murder herself, as the local gendarmes don't seem to be having much luck. So...whodunnit? As soon as more folks showed up on the scene, renting rooms for Ally, the identity of the murderer(s?) became more clear. I still enjoyed the descriptions of the scenery; the new lab puppy; and the townfolk, even though this "Scottish" mystery was obviously written for an American audience w/ many stereotypes thrown in. 4 stars.
