Sanag B3 headphone review: Probably the cheapest noise reduction headphone recently
I have also used some low-end headphones and added noise reduction, but the actual effect is basically not felt. This time, a British brand Sanag, its B3 Bluetooth headset also uses active noise reduction, but the price of this headset is only about 500RMB.
Eachine Trashcan is better than the Mobula 7, right?
The Eachine Trashcan is a 75 mm ducted whoop that in almost every way is an upgrade to the incredibly popular Mobula 7. It has bigger motors (0803 to 0802) it uses an F4 flight controller instead of an F3, the VTX is switchable from 25 to 200 mW instead of being fixed at 25 mW and the Trashcan has the superior camera in the Caddx EOS2. So the Eachine Trashcan is clearly the better quad, right? Well…not so fast.
ZLRC Beast CSJ-X7 – A 4K drone under $150
The ZLRC Beast CSJ-X7 is most definitely an intriguing option. It is the first GPS drone with a 4K camera that we have seen to release for less than $200. This really could be a game changer. It boasts a handful of intelligent flight modes and an impressive flight time of 23 minutes.
Eachine E013 Plus – An awesome FPV quad
The Eachine E013 Plus is a brushed FPV microdrone. It features powerful 8520 motors, a 1000 TVL camera, and comes in a variety of ready to fly packages. This is an excellent low-cost option if you are looking to get into flying FPV. The E013 Plus even features a flip over after crash, aka turtle mode. That may not sound like a big deal but when you are learning to fly FPV it is an absolute time saver.
Happymodel Snapper 7 first look: Blast to fly
The Happymodel Snapper 7 is a 75 mm tiny whoop style drone. It is a blast to fly, mostly in part to its powerful 0802 19,000 KV brushless motors. It may not have the name recognition of the Mobula 7, Tinyhawk or Trashcan but it is definitely worth a look. If you are like me and you enjoy a good brushless whoop then you’ll want to take a look at the Snapper 7.
HBX68 review: Tinywhoop with 2S power
The HBX68 is a super light and small Tinywhoop that will fly on 2S power. It measures just 68 mm from the motor to motor and weighs in at 25.6 grams. If you want a small and lightweight quad for flying indoors then this definitely is worth taking a look at. It is smaller than the popular Tinyhawk, Trashcan and Mobula 7 but slightly larger than the typical 65 mm whoop. Has HB found the sweet spot? Let’s take a closer look.
iFlight CineBee 75HD – Cinewhoops is legit!
I love flying FPV and in particular, I prefer flying micros to full-size quads. They are smaller and draw less attention to them. I can fly around the park and people won’t give me the evil eye. Cinewhoops are my newest favorite flavor of a quad. I can do a lot of the same fun maneuvers but I can capture it all in high definition. The iFlight Cinebee 75HD is a 75 mm version and is a lot of fun to fly. Keep reading to learn more.
