The Fullspeed Tiny Leader is a new sub-micro class quadcopter from FullSpeedRC.com that is ducted and competes in the now popular and increasingly competitive brushless whoop market. Full Speed is a now well known and respected producer of micro brushless quadcopters including the original Leader 120 (review here) and more recent Leader 2.5 (review here) and Leader 3 (review here). Below I will outline the published specs and what sets this apart from other brushless whoops - good, bad or indifferent. To clarify there are 2 current Full Speed Tiny Leader models: The TinyLeader Regular and TinyLeader HD with onboard HD recording. This review is for the TinyLeader regular
The Diatone 2019 GT R249+ is one of the newest series of micro quadctopers from Diatone that is built around the Mamba mini f4 stack.
The full range from smallest to largest includes:
As you can see there is a high degree of modularity - for all except the largest they share the same 1105 5500kV motors. All sizes feature a 3mm thich carbon baseplate except for the R239 which uses and injection moulded plastic chassis and prop-gaurds. All models share the same injection moulded lightweight canopy and mamba mini f4 stack.
I've chosen to review the R249+ since my experience with micro quadcopters has lead me to believe that this is the 'sweet' spot in terms of performance and staying small and discrete when flying.
