XLPower’s Nimbus 550 is the latest generation 550 class helicopter, utilizing proven design techniques found on the Specter 700 series. The result is a good looking, lightweight, and robust airframe with plenty of options available to customize the appearance and flight style.
One of the most notable qualities of the Nimbus 550, and proven on the Specter 700 V2, is the use of a large diameter tail boom (27mm for the Nimbus 550) without the need for boom supports. Not only does a large tail diameter tail boom increase tail performance, but also has a super sleek look.
The tail servo and tail control rod are mounted in the upper frame raising the vertical CG to improve flight characteristics.
The core of the airframe is a single piece 7075 aluminum bearing block assembly and servo mount providing rigidity to the frame and drivetrain. The main shaft is supported with large double row angular contact bearings increasing durability and bearing life to ensure long-term operation.
The cyclic servos are arranged in a 120-degree layout for optimal control geometry and motion over the entire control range.
Two kit versions are available based off the pilot’s servo choice: a mini cyclic servo or standard size cyclic mounting bracket.
Mini cyclic servos can reduce cost and are lighter weight, while the standard size servo option includes a third main shaft bearing block to support more powerful and robust servos.
Both kits use a standard size tail rotor servo and the cyclic servo size mounting assembly is interchangeable with a minimal number of parts. All these components are mounted on high quality 2.5mm thick carbon fiber upper frames and lighter 2mm lower frame plates for unmatched frame strength and crash resiliency.
Similar to the Specter 700 V2, the Nimbus 550 battery tray system is able to be loaded into the helicopter from the front or the rear, enabling the optional quick-connect system in which the model to be powered up/down instantly without removing the canopy. The battery tray accepts all standard configurations all the way up to 12s power systems!
Designed to accept the most powerful power systems, the main gear hub consists of two one-way bearings providing reliability for the most extreme power combinations. A rigid motor mount is fixed directly to the frame’s main support structure, reducing flex under load. An optional second motor shaft support bearing is available for further rigidity.
Every detail has been tested and proven to give pilots the best performance and functionality, such as sacrificial blade grip arms designed to bend or break in a crash, one-piece tail box to simplify the build process and replacement of tail shaft bearings, a damped tail rotor system that stays smooth even at high RPM, plus a low and wide landing gear increasing ground stability; reducing the likelihood of tip-overs in autorotation and hard landings.
With an average flying weight of ~2.9Kg (outfitted with a 5200mAh 6s LiPo) the Nimbus 550 will meet all demands with agile, responsive, and a confidence building feel… flight after flight.

Cute, soft, quiet and durable
This stuffy is HUGE! I was expecting it to be half this size. We're happy to have a stuffy that does *NOT* have a squeaker. We're finding it to be very sturdy. My 4 month old puppy is a terrier mix and she loves to attack and shake stuffies and you can't tell this thing has been abused at all. Looks the same a 2 weeks later as it did new. It's one of her favorites and we love it because its quiet. Should last a long time.
This is an update 4 months after purchase. The red squirrel continues to be a favorite with my puppy. With other plush toys, she tears them apart in 10 minutes. This one, somehow, has lasted months. Over time, she has pulled off the tail, the ears, and two of the legs, but the body is still intact. Amazing!

My dog freakin’ LOVES this
Favorite toy of my dog. He’s a heavy chewer - and yes, he’s chewed the tail off and one of the ears - but he carries it around all the time - plays with it all the time - even sleeps with it. And it has held up for months. I’m getting another one just to have as a backup as I don’t think he can live without it. Also love that the eyes are embroidered and not plastic so he won’t accidentally swallow them. Best toy ever.

Finally!
I search constantly for toys without a squeaker and never seem to find one. My curious pup loves ripping them out so I stay away from them. But finally one that he loves but has no interest in tearing apart because it has no squeaker!! Win!

Squeakerless
It is very life like. Held up well but is starting to show some wear after 6 months. I attempting to repair a couple of holes that have shown up. The sqeakerless is nice but would love a noiseless squeaker. I would give 5 stars if I can patch the holes.
