X25-1 Space Explorer Flying Car
This Christmas a popular gift was the X-25 which can race around on the ground and take to the air when throttled up. While in the air engage the 3D Eversion System and perform stunts and flips with ease. The auto return function lets you recall the drone back to its take-off point.
While the x25 is made by SongYang, there is also a Syma X9 version out there that looks exactly the same. Syma does make really good helicopters, so that is another consideration.
JJRC H5C Mini Quadcopter
We have test piloted large scale commercial multirotors over the last 2 years and have not tested a new mini quad since our video Hubsan H107D that attracted 401,623 viewers . A lot have changed very quickly, a greater selection, more competitors have entered the market since then. So last week, a friend from GearBest.com sent us a JJRC H5C, a mini quad, a 6-axis, at 23 cm, just the size of a Tali H500 propeller, to show how mini / micro quads have progress today.
FIRST IMPRESSION is the mini quad is really light, and it floats quietly in the air. It was actually so surprisingly light. This is of course the direct outcome of the brushed motor used, old school but it fits the purpose of achieving better flight time and cost of production. The frame has a texture that felt like a recycled egg carton, but made of a strong thin plastic molding. It carries the 3.7V 500mAh rechargeable LiPo battery for 6 minutes of flight time. We tried putting a smaller Ladybird or H107D LiPo, and it worked perfectly fine…
Understanding propellers directions on multicopters
If you find your multi-copter flipping on take-off or just don’t seem to take off, the first thing to check is your propellers or motors. If your propellers are spinning on the wrong direction, the thrust might just be pushing your copter down instead of lifting it up. If you have the propellers in the same orientation next to each other, it may just topple your copter. Propeller are usually marked with the spin direction and they should match the diagram illustrated below…
Walkera QR X350 Pro
Year 2014, time to look for a low cost, quick to assemble quadcopter, to be modified with FPV gear, something to travel with, overseas. So we purchased the Walkera QR X350 which can be assembled in 2 minutes, with no tools on hand. Today, our SAR teams were informed of another exciting version of the 350 size, the QR X350 Pro that uses Mission Planner. Lets see how hardy this drone is, as we take it for a stress test in every way… yeah.. in extreme ways..
First Impressions: I must say the X350 Pro flies very well, pre-tuned. It Loiters perfectly out of the box. sure enough, it did every standard thing with the Mission Planner. The only thing, out of the box, without any modification I am not able to add telemetry module or osd, however others have managed to solder them on…
Hubsan H107D FPV X4 Quadcopter
Synopsis: Occasionally we have the opportunity to test out some of the new entry level quads in our lab. So this month we have something special, the smallest First Person View (FPV) ready-to-fly quadcopter made by Hubsan, a contender to the popular Ladybird. It is quite amazing how Hubsan is able to pack everything, including a camera and video transmitter into a quad, smaller than a Ladybird, with 6-axis gyro flight controller. The package even comes with a radio transmitter, video receiver and a blight large LCD screen, ready for beginners to start flying first person view and filming. This may be one of the best seller of all time, this model enters the market at the right time and right place.
Hubsan X4 H107D actually comes with one of the more impressive printed Instruction Manual I have seen for a while, it actually explains everything you need to know in great detail and well written…
