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.
Looks familiar? Our favorite lightweight FPV camera 808 or Mobius faces another match, the new EKOO S090. We will do a side by side comparison and load it up on a plane and take it for a flight. It cost less than a Mobius and has a time lapse function, photos with delays between images range from 0.25 to 60 sec. Loop recording the usual, useful for security cameras. Like the Mobius, the Power button has a delay to prevent premature activation while handling.
There are 3 versions of lenses: H 140 degrees, V 102 degrees, D 170 degrees…
TAROT OSD mini TL300L perfect for 250/300 quadcopter size, allows you to configure directly on your monitor/goggle. It is intended for a racing quad, but can be used on any FPV models. it uses barometer to determine the height and and GPS module for position.
INSIDE LOOK:
OSD video overlay system has the following features: VTx Voltage, Eng Voltage, Flight Time, Flight Speed, Flight Height (altitude), Home Direction, Home Distance, Total Voyage (duration), Lifting Speed (vertical), Longtitude Latitude (GPS), Satellite Number (Count), Azimuth (location of the plane in the sky from the perspective of the base station). HOME OK is set when 6 satellites count are met…
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…
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… Continue reading Understanding propellers directions on multicopters
Synopsis: I have been compiling a list of terminology and abbreviations over the years, some going back a long time ago when I was kid in the 70s. This list keeps getting longer each year, with new buzz words in the RC Drone arena. Hope this helps and thanks to many who contributed over the years.

Flying a Navy EDF Fighter Jet. Synopsis: It is a normal progression at some stage if you are still into this hobby, to begin exploring EDF Jets. So we began our journey to look for a reasonably priced EDF, at least 64mm, moderate speed 60 mph that uses our existing 2200 mAh 3S LiPo we use for our FPV Planes and Quadcopters 350. The F9F Panther met the perfect fit for just under $85 shipped or you can locally pick it up for $70.
Specification
•Wingspan: 27 in (685 mm)
•Length:730 mm (28.7 in)
•Flying Weight: 1.2 lb (552 g)
•EPO foam construction
•64mm EDF
•Motor System: 4300KV outrunner brushless motor
•Speed Control: 30A ESC
•Servo: 9g micro servo (3pcs)
•One 3S 11.1V 1500mAh-2200mAh LiPo at least 20C
Features
•Quick assembly PNP
•Designed landing plates
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…
The Parkzone Ultra Micro P-51D is based on a Realistic 334th Fighter Squadron trim scheme with 4-bladed prop running off a 8.5mm brushed motor. It uses a DSM2/DSMX receiver with Artificial Stabilization 3 aXis (AS3X, giving you smooth flight performance and yet full control authority over your plane.
Specification
Wingspan: 16.2 in.
Overall Length: 14.1 in
Flying Weight: 1.5 oz (43 g)
CG: 1.38 in (35mm) behind the leading edge at wing root
Recommended Battery: 3.7Votes 1S 150-180 milliampere hour LiPo
Feature: The AS3X turns on when throttle is raised and handles turbulence, moderate winds well, allowing you to perform aerobatics comfortably…

I tend to just yaw (rudder) for a quadcopter to turn, even though I find myself always using the aileron stick to reduce a skid and create the effect of a turning plane when filming for fun. If you are spending your money on a camera gimbal, than you will probably be keeping your quadcopter as level as possible on all turns.
As for planes, they tend to bank over during a turn, so this changes how you actually use your sticks. The easiest way to understand turns is to visual the elevator as becoming more vertical (so it acts more like a rudder) and the rudder becomes more horizontal (so it acts more like an elevator) during a turn. The results of turns for most RC planes, the rudder really isn’t useful as a rudder except when you’re entering the turn (i.e. plane hasn’t banked over yet) or exiting the turn (i.e. plane is almost back to level). Some trainers actually recommend applying opposite rudder during the turn to keep the nose up for a smoother turn, since the rudder is acting more like an elevator. However in most cases, during the turn the elevator makes a perfectly good rudder and you can therefore just fly with ailerons and elevator with minimum throttle. Hope you got all that, as that was a early lesson I had before taking my first fixed wing flight…
