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.
