ODRVM 4k action sports camera

The latest actions sports camera ODRVM 4k talks.  We took it out to compare with the Git2 camera.  Here are some sampling of footages filmed at Disney.  These ultra vivid cameras are becoming very affordable these days. ■ by dronemission.com

User Segment
Camera Enthusiast, Budget $69 (May 2017 source: Amazon)

Our Notes

The ODRVM comes with in a very nice case with accessories, a user guide in 4 languages.  It comes with a remote controller, a great way to start/stop a recording from the distance or when the camera is placed in a location not easily reachable.

Lets take a look at the camera.  On the front we have the power and mode button.  The shutter/recording button is on the top with a LED indicator.  By placing the LED indicator on the top, helps to prevent a blinking reflection while filming closeups and through a window.  The back contains the 2″ LCD screen for framing shots. Battery compartment is at the bottom. Right side has the button that allows you to scroll up and down button, a speaker and the WiFi on and off button.  On the left side has a micro USB, micro HDMI output, microphone, and a micro SD slot.

It is slightly bigger than a GoPro 3, but is actually lighter, weighing just 63 grams.

The details are sharp, colors are vibrant.  The ODVRM has an excellent wide dynamic range, even when a subject is backlit by the sun, you can usually see their face.   The saturation is good without looking over-done.

The white balance on the camera adds colors to balance the light source, for example on a overcast day, the image can look bluish if left unadjusted. This auto white balance control in your camera sees the cool color temperature and adds some red to warm the colors, as a result you may see a tint of red.

The  menu system is straight forward, simple to use and intuitive.  The settings selected are displayed on the screen which is absolutely useful to view before you begin filming.

Voice prompt can be useful in some situations, it prompts you when your battery is low and each time you start and stop recording.  You may find yourself turning it off after a while, unless you plan to edit out every voice prompt on the recorded videos.

The field of view options are 170, 140, 110 and 70.  Anti-shaking and gyroscope is available as a option.

odvrm-fov

A feature we like is the auto time-lapse, a mood feature to capture moments in time.

The maximum photo size is 20m and UHD 4K video at 24 fps or more popular at 1080p 60 fps or 720p at 120 fps.

Filming at 4k is sharp, but not as smooth, and that seem to the same problem with the Git2.

Eachine VR D2 Pro Focus Adjustable

Just over 3 years ago, we had a challenge finding an affordable pair of goggles for FPV, let alone a DVR.  Eachine VR D2 Pro Upgraded Goggle delivers an All-In-One (AIO) solution with built-in diopter correction lens, a DVR, dual diversity receivers, with RSSI, includes a tripod mount and best of all within budget   ■ dronemission.com

User Segment
FPV Piloting, Off the shelves.   Budget [$] (PRICE CHECK: $89.99 ■ May 2017 Arthur’s Pick)

What To Expect

This is what I have been waiting for, corrective lenses for people who wear glasses, nearsighted, this helps just a little, I wouldn’t say it is compatible for everyone, but I can now read the osd without glasses having been using -2.0 diopter on all my other goggles.  I have the lens slide all the way to the front.  There is a slider on the left and right, and you just adjust it to best fit your eyes.

The menu system is broken down into 5 sections.

What I like about the upgraded functions are the On Screen Display (OSD) and Recieved Signal Strength Indicator (RSSI).   The voltage of the goggle battery and frequency selection is shown; it is not recorded, but overlays on your screen. It is suggested that we calibrate the RSSI before each flight. The A&B signal strength helps me identify the direction of a lost aircraft to some accuracy, as you can hold the goggle against your chest and rotate around, and then foolow the direction with the strongest signal.

It accepts upto 64 gb of memory storage and records at 16000 kbps Bitrate at 29.97 fps.

Makerfire Micro FPV Racing Drone

Makerfire Micro FPV Racing Drone is the latest entry into ducted fan micro racers joining the Tiny Whoop™ race. For the value and money, this quadcopter comes Ready To Fly or also available Crazepony the Bind-N-Fly version with DSM receiver.  We received a BNF version from GearBest to test against a Devo 10 Deviation with DSM protocol and the results are good.  ■ dronemission.com

Market Segment
Beginners, Indoors, Park Flyers, Ready To Fly, Off the shelves,  Budget [$] (PRICE CHECK: $64PNP ■ Mar 2017 Sara’s Pick)

Analysis

Micro quadcopters have come a long way, with Jesse Perkins mounting a small FPV camera and video transmitter, showcasing some amazing indoor racing and calling it the Tiny Whoop™. Several manufacturers have since began to introduce their version of affordable ducted fan quadcopters and Makerfire Micro is noted to be a good entry in this category of indoor racing.  The tall propeller guards allows the micro quadcopter to bounce off the wall without damaging the fans (propellers), surviving most crashes.

It is also beneficial to note that when paired with the popular opensource F3 flight controller, manufacturers are able to lower the cost of production.  With a F3 flight controller, pilots can get several flight modes available instantly.

In Rate/Manual/Expert, this mode is the most challenging flight mode which uses the gyroscopes from the flight controller while the accelerometer is disabled .  It allows the best control of the quadcopter, allowing pilots to do some amazing hairpin turns and aerobatics. This will however require some experience and not intended for beginners.

In Angle/Stability mode, the accelerometer is activated. This enables the quadcopter to self-level. If you don’t put in any input, the quadcopter will remain level. This is the mode that is used on the budget entry level quadcopters. It is however a great way for all pilots to practice control and orientation by flying in a number 8 pattern

In Horizon mode, this is a mix between Rate mode and Angle mode. It gives a pilot the best of both modes to perform flips and rolls and yet self-levels when the pilot centers the sticks but with Rate mode at it’s endpoint.

In the early days of racing drone, an inexperienced pilot would suffer a flip of death (FOD), but to the rescue, came “Air Mode”.  In Air mode, pilots will be flying at all throttle levels, so if you chop the throttle, the stability corrections still come into play, even at minimum throttle, allowing the pilot to perform some amazing maneuvers at low throttle rates.

You will have to assign Air Mode as you would to a switch when setting up flight modes within Betaflight.  The suggested best practices to test Air mode are:

  • Arm motors (motors start spinning idling as an option)
  • Enable AirMode with switch (check to ensure no idling windup on ground)
  • Lift off and fly around (motors will never stop in flight even at lowest throttle and self levels)
  • Just prior to landing, disable Air Mode by switch (as a safety)
  • Land and disarm motors

The benefit of using ducted fans is they are fully protected and prevent the fans from causing any damage to walls, as well it is safe enough to be caught by hand!

One of the best kept secret of a Walkera transmitter is the ability to support multiple protocols with opensource Deviation. So if a pilot is flying a selection of models, such as Walkera, Blade, Eflite, Hubsan x4, Parkzone Micro Warbirds, Spektrum planes, you can turn an affordable Devo transmitter into a power house that supports these protocols.  With a Walkera 12E 12 channel radio transmitter selling at $85 versus a Spektrum JRP12 at $1249, you can see the cost benefit of marketing a Walkera Devo 10 or 12E for micro racing drones.

Pilots can easily spend 5 minutes on each flight, setting up and flying. The actual flight may last 3-4minutes. On a Mode 2 radio transmitter, throttle stick is on the left.

Binding the Makerfire Micro to a new radio transmitter can be a challenge, you will likely need two pairs of hands to hold down the bind button, at the same time power on.  However, you only have to do this once.

Once you have your radio bound to the Makerfire Micro, you will want to run some tests within Betaflight Goggle Chrome App.  You will need a USB cable to connect your quadcopter to a computer.  Make sure your throttle is within range, and the receiver is responding in the right direction for all stick movements.

To begin your first flight, power on your radio transmitter first, make sure your throttle stick is at the lowest point. Check to make sure all your switches are up (position 0). Connect your battery to your copter, lay the copter flat on a hard surface immediately.

Move your left throttle stick down to the lowest point and to the right, to unlock (arm) the motors.   The copter is now live.  To lock (disarm), move your left throttle stick down to the lowest point and to the left.  You can change your setup to switches with Betaflight.

Flight Characteristics

The Makerfire is easy to fly on Horizon mode and can be switched to Angle mode or Rate mode.   It accelerates at a high speed, so setting up dual rates is a good idea.  Low rates at 70 scale on 30 exponential is a good start.  It survived all of our indoor and outdoor crashes, which makes this quadcopter a hardy little thing.

Eachine Micro Skyhunter 780mm FPV RC Airplane

Skyhunter, has been an all-time favorite plane for lots of long-range FPV pilots. Eachine doing it’s match, takes on the micro version, at 780 mm, 3 channels, plug and play.  Take a break from the racing drones, here comes a racing plane.   If you are looking for a budget, simple hand launch RC FPV plane with some speed, you may be in luck.  ■ by Leo @dronemission.com

User Segment
Keen Beginners, Park Flyers, Plug and Fly, Budget $59 BNF (source: Dec 2016 Banggood)

What To Expect

The Micro Skyhunter FPV is one of the coolest miniature version of the Skyhunters released under the label of Eachine.  I have here the FPV version with 40 channels and 800 tvl camera which you can just slip on or remove anytime.

The Skyhunter comes in this small box just under 1 1/2 feet, very well pack, box in a box and individually wrap.  All electronics are pre-assembled,  plug and play, so you can begin flying on the same day.  It comes with a few cabon fiber spars, the main spar and re-enfocement along the wings.  You can see the signature look of a skyhunter with two veritical stablize.  I like how everything is pre-installed, 5 grams servo, servo linkages are all ready using JR connectors.  Included is a Hobbywing 20 amps electronic speed controller(ESC) with a XT 60 plug.

There is plenty of room, you have three separate compartments, one section for your receiver and flight controller if you are using one, and a two in one canopy held on by magnets for the battery and a convenient camera fpv bay.   The wings are held together with two bolts.

The camera is pretty good, other than the 25 mw range limitation, we have no complaints. You can of course always use a different video transmitter.  There are some crack lines, along the joints, but nothing too serious, I just add a little tape along it and tape along the leading edges, wing tips and base for additional protection and to prevent wear and tear.

eachine-micro-skyhunter-unbox.jpgMotor is powerful for this size plane, 2300 kv 2204.

The camera comes with a holder plate, very nice, and you simply secure it on the camera bay when in use.  I just tape the plates down for easy removal.

Decals are included, but I like my usual red/blue white colors.

Overall, this plane has everything you need, easy to assemble as all the electronic are installed.  It uses XT 60 which means LiPo batteries are easily available in the market.  The bigger question is, are you up for a 3 channel plane, if you are, this is definitely a keeper within budget.

Flight Characteristics

Tracks very well, but not a great glider.  We are currently completing a few more flights before reporting back.  Standby.

XK X300 Quadcopter

XK X300 quadcopter. XK Innovations has made several great budget quadcopters, so this is a welcome innovation to include an optical flow sensor in their latest XK budget quadcopter.  An optical flow sensor is a vision sensor capable of measuring optical flow or visual motion and producing a measurement based on an image sensor chip connected to a processor programmed to run an algorithm.

xk-x300-optical-sensor.jpgMarket Segment
Beginners, Park Flyers, Ready To Fly, Off the shelves, Budget [$] (PRICE CHECK:  Jan 2017 Sara’s Pick at Gearbest)

What To Expect we took this budget quadcopter for several flight tests. If quadcopter piloting is new to a user, the auto take-off is a nice introduction for beginners.   The optical flow sensor performed flawlessly, providing a good position hold. With the help of the barometric sensor, the quadcopter tracks pretty well flying straight, low while holding it’s altitude.

It seemed sluggish at times during flight with the brushed motors with the default 60% low rates. Brushed motors are one of the simplest types of motors that uses an armature, a commutator, brushes, an axle and a field magnet.  The advantage of using brushed motors is the low cost of production, they are replaceable, but the speed and torque is moderately flat. At higher speeds, brush friction increases, thus lowers the speed range due to mechanical limitations on the brushes.  Sand can easily get into the brushes which can affect it’s overall performance.

The yaw turn is fast, so completing a coordinated turn with the aileron stick will provide a better bank turn. The descent is slow and controlled by the barometric sensor.  On the positive side, it is not going to drop if the throttle stick is lowered too fast. The x8 radio transmitter includes an auto-flip function. The auto-flips could be improved, as it requires the user to release the stick to a halt or it will keep flipping while losing altitude.

Users can easily spend 20 minutes on each flight, setting up and flying. The actual flight may last 15 minutes or less.  ■  dronemission.com
