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.

Good book, mediocre edition
Format: Paperback
This review pertains to the quality of this edition's editing and construction, rather than the content of the book itself. Rest assured that the text itself remains a valuable piece of introductory theory.
The book is fairly well constructed, with paper and a binding that is sturdy enough for general use. However, my copy had several manufacturing errors including folded over pages being stuck into the binding. In addition, there are several misspelled words throughout the text and some obvious typos (missing letters, incorrect capitalization and punctuation) that did not majorly impact the readability of the text, but were, nevertheless, annoying.
Considering the low price of this edition the manufacturing errors are hardly a big deal, but I would have preferred the text itself to have been treated with more care and respect while being prepared for printing.

thoughts on Xi Jinping
Format: Kindle
This book was highly organized and very easy to comprehend. I have formed a much better understanding of Xi Jinping and where he is taking China. Although I feel he has been thoughtful and successful in some areas such as improving China economically, I don’t feel his autocratic approach will succeed in the long run when more Chinese people will demand to be heard. Just as Mao thought didn’t outlast Mao, Xi thought will not outlast Xi.

The Book I Meant to Write
Format: Kindle
While doing my master’s degree in international relations, I completed a master’s thesis on Xi Jinping Thought (which, like the authors, I shortened to Xi Thought). I considered writing a book on the subject since there wasn’t a lot in English, but I no longer feel the need. This book fills every gap that was present. Well written and informative, it is the quintessential English source in Xi Thought.
The authors put Xi’s political thought in a consultative Leninist paradigm and define that context clearly. Each chapter elucidates a little more and puts Xi thought front and center in China’s current transformation. I consider it a must read.

Great read and most importantly very topical
Format: Audiobook
The writers use published work of Xi and Chinese government official statements to describe the true nature of this most important Chinese leader who will have profound impact on the total world.Like it or not it is essential for all of us to really what he is preparing his nation for the vision he has.Americans are naive and totally ignorant.

Pure anti-China propaganda
Format: Audiobook
From the first few sentences they get the name of the ruling party of China wrong and it only gets worse from there. This is purely a work of western propaganda and in no way academic or objective. I've studied China for many years. You will find nothing of value from this book.
All of their achievements are minimized or disregarded entirely. You will also notice that very little data is presented if any at all.
