The Sailfly-X is a new quadcopter made by Happymodel that is due for imminent release. The objective of this preview is to run through the specifications published and comment on their suitability for this build and expected performance. A review will follow as soon as the first round of reviewer samples are available.

As you probably know, Happymodel's most successful launches have been based around the all in one crazybee board: the snapper7 (reviewed here), mobula7 (reviewed here), eachine trashcan (reviewed here) and the mobula7HD. The Sailfly-X is a departure from the ducted design in response to the massive performance gains shown by Kabab as above. Lets have a look at the specs below and I'll give you my thoughts and a conclusion based on the entire package.
That wraps up my review of the component specs. As a package it looks like the plan on retailing at $89 which represents really good value for money - that would only buy you the motors and flight controller right now even if they were in stock (which they are not!!). The overall build looks solid but my main complaint is too high motor kV and too low VTX power but in the scheme of things these are not major. The thing I am most pleased about is the light weight. This is VERY light for such a quad and is sure to perform in terms of flight. Of course, please take this preview with a pinch of salt, until I do my full review it is conjecture but does represent my best guess at this stage.
