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.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing.
He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.

My dog loves it!
Style: Ball, Size: Medium (Pack of 1)
This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.

Our first babies favorite and longest lasting ball yet and he is fixing to be 7.
Style: Ball, Size: Medium (Pack of 2), Style: Ball, Size: Medium (Pack of 2)
Toughest ball we have found yet. Our doberman loves Chuckit! Balls especially the crunch one. He spreads all the balls and toys we have bought but these lasted the longest. The crunch and the glow in the dark are usually his pick but he has several different choices.

My Doxie’s Absolute Favorite Fetch Toy – Who Knew Baby Balls Could Be So Paw-some?
I bought these colorful baby balls as a simple toy for my little one, but my furry bay claimed them as his own from day one! These small, bouncy balls are perfect for little dogs – they’re lightweight and easy to grip in his mouth, keeping him entertained for hours. No squeakers or stuffing to destroy, just pure, durable fun. If your pup loves a good game of fetch or just batting things around, these “baby” balls are a steal. Highly recommend!
