High Great Mark 4k Wifi Fpv Rc Drone

Loftier Great are a Chinese drone manufacturer that has spent years producing white-label drones for companies such as ZeroTech (Hesper) and Mota (Lily Next-Gen), at present they have just started to transport their first oversupply-funded drone to backers via Kickstarter.

Despite show-casing at the CES 2017 show over 12 months ago, the Loftier Bully 'Marking' drone has only completed its Kickstarter entrada and shipping procedure has commented, however backers of the campaign are frustrated at the slow speed and lack of communication from the manufacturer.

Raising simply over £250,000 ($300,000) in just 45 days via 1,193 backers, the campaign completed officially in July only drones are arriving with customers very slowly and many are being charged an unexpected import tax/duty on arrival.

This small and highly capable drone retailed for $239 via the entrada perk arrangement, nevertheless the product model has already appeared for under $200 via online stores such every bit GearBest, this has clearly upset backers.

With no GPS and downward facing optical flow sensors, ane might wonder how this drone is capable of stabilizing its position, simply the impressive Qualcomm Snapdragon incorporates VIO (Visual Inertial Odometry) which via a 45 degree downward facing camera allows the drone to 'learn' its surroundings visually.

This system does however have limitations, specifically that the VIO photographic camera must exist able to see patterns and objects of reference, without which it tin can struggle to concur position outdoors.

Put simply, if the VIO camera tin can only see the nuts textured green grass of a field, it is unlikely that the drone will maintain its position, therefore the drone must be flown at a higher altitude and then that other elements are visible for VIO cess.

Some backers are frustrated that these limitations were not made clear during the entrada, as but with prior experience of drone technology could these technical restrictions be known by backers.

The Mark features a compact 4K camera sensor which delivers crisp quality footage and photos, disappointingly it can simply offering stabilized video at 1080p due to the cropping, panning and scanning required by EIS (Electronic Image Stabilisation), but the result is still positive.

In addition, the pocket-size onboard battery offers a long flight time and the indoor flying capabilities are impressive equally per our review below.

Where to buy…

The Mark drone is available via Amazon or straight via GearBest where it is currently retailing at the lowest price.

The positives…

❍ Fairly low-cost for 4K video, great photos and good flight time
❍ Portable, folding and lightweight design
❍ Very impressive VIO technology although primarily for indoor
❍ Really captures 4K, it doesn't downscale the files saved
❍ Decent flight time over 15+ minutes
❍ Indoor route-retention is very impressive (but useful?)

The negatives…

❍ No GPS/GLONASS capability
❍ Cannot fly in night and struggles in air current
❍ No transmission or controllable tilt on the camera
❍ EIS only available at 1080p, 4K is unstabilised
❍ Risky to fly outdoors incase VIO fails, no reliable RTH
❍ No USB charging port for batteries, requires transformer
