About

** Before proceed to read further about my UAV Drifter build first visit my my archive page on (2012) FPV-Drifter Ultralight first for some basic building tips because the one i explain here is just extension of archived tips.

uav drifter ultralight 43Its almost been 5 years since we had talk about Drifter Ultralight on FPV and throughout its lifespan it has garner lots of follower, fan based and most importantly epic amount of adventure in the skies flawlessly with videos of jaw dropping beautiful FPV flight not only from me but also from other enthusiast spawn all over the world, on Youtube and other online social media.  On my side now i own 3x Drifters Ultralights that runs with different flight roles.  Somewhere in mid 2015 my third Drifter Ultralight build seems to do the impossible unlike any other FPV setup in the past.  Infact it was no longer an FPV, its now a full fledge UAV specification.  So in this article we're talking about UAV specification on my 3rd ES Ultralight build (UAV Drifter Ultralight #3-V5).  Its the only Drifter that can fly uav drifter ultralight 48autonomously from the start till the end of the flight without any user/pilot input along the way.  Mission based flight feed into the plane and off it goes to explore the world autonomously or robotically at long range.   Considering the fact its only at 950mm wingspan wait till you hear it actually carry almost 3x more lipo battery capacity than original FPV specification or almost 5x more capacity than manufacturer stock/default specification which is something impossible to carry for small size plane but yes i prove it it can!...it carries monster size 5200mah 3s lipo battery rated 40C!   Despite being a UAV the Drifter come with a necessary companion the 3DR data radio telemetry ground station which needed as proxy between the aircraft and the ground pilot/crew as intermediately link between them to send in-flight live telemetry data to the user via handheld smartphone (Android) or computer for pilot/crew monitor the lane actual position/data and may send updated mission parameter to ES Drifter Ultralight.  Drifter lives on with new leash of life in UAV world.   Now lets read it all about it.

Building

When i acquired a third second hand 'crashed' kit from one of our local R/C flying member, it was dented, torn wings especially on aileron and almost smacked nose..which is why as you can see the front nose looks slightly blunt and shorter that original stock looks on min Drifter.  I bought it at cheap uav drifter ultralight 102price, give it some love by fixing it, rebuild it and gave it a second chance in life under a new ownership.  I installed APM Mini Pro flight controller as core flight system with intention to FPV it later on.  The hardware differences between this one and the old FPV specification Drifter was it fitted with APM Mini APM, MinimOSD, 3DR telemetry system, APM power module, mic-less Skyzone 5.8ghz 600mw rated video transmitter and a 1g 520TVL cmos camera embedded in the nose angled almost 20~25 degree downwards for live view piloting.  Second camera is mounted with RUNCAM V1 HD camera loaded a month later located between landing gear inserts for HD recordings.  3DR telemetry radio located on the end of the plane tail which give a good separation away from sensitive RF emission from BEC, ESC, Servos, VTX, motors and camera which might capped the data telemetry transmission uav drifter ultralight 107strength.  It doesn't have pan-tilt camera capability which is unnecessary for UAV type flight because i won't be around looking in realtime when its flying by itself, thus shave extra gram out from the plane.  On the plane itself some changes have been made to make it a UAV platform worthy: all the scale seat and pilot figure removed so that the front have more bigger space to place much bigger capacity and longer size lipo battery (5000~5200mah 3s 30~40c) and the main wing structure have been embedded with 3 rows of carbon rod as main spar to increase wing loading and rigidity.   The CG remain unchanged despite having bigger and heavier battery.  The landing gear both wheels struts end have been bridge together horizontally via thick zip ties to avoid it from bend and spreading sideways due to overloaded weight on front end during landing. Unfortunately 50% of the time it doesn't perform well on rough boingy terrain during landing causes the landing gear to bent and nose in and break the ziptie bridge. It only works well if it was a controlled landing (' controlled elevator up' landing) or on smooth concrete/tarmac runway. 

 

UAV building level difficulty/rating: Hard/Advance (2/10)
UAVequipment setup grade: Advanced
Building hours required: 48 hours
Skill required: Soldering/Foam cutting and ARDUINO programming for APM based hardware.
Critical issues during installation: Keeping the weight to most minimal.
Required additional mods/must do improvement: Beef up the motor mounting/solid reinforcement + re-glue all control hinges + landing gear + wing reinforcement.

APM parameters lists:

Here's the list of parameters used by UAV DRIFTER ULTRALIGHT #3 (Version 5) build. All the parameters are based on Arduplane V3.4 firmware. Some lines of parameter have been removed because parameters setting such as compass, acc and gyro sensors are very much based on "locality" factor setting which you need to do calibrate it by yourself. So copy the below parameter manually.

*Note:

  1. Assume you use the same hardware a setup as this build
  2. Different radio transmitter mode/setup requires different radio channel calibration range/PWM signal and flight mode.
  3. This parameter optimal for full flying weight approximately 850gram. Different weight, CG, motor combo power, or different servo performance/throw requires extra tuning.

UAV flight characteristic and performance

If you've been following FPV Drifter development and its epic adventures since 2011 and onwards it is no doubt that this platform is a superb FPV platform not only for scale like cockpit FPVuav drifter ultralight 49 flight but also general multipurpose flying.   It handles well  in many sort of condition, dry hot weather, cold wet clouds, over the clouds, long range and etc.   As an FPV plane it has shown its stars high flown above the clouds.  So what about in UAV autonomous  flight configuration will it fly as good as manually driven FPV setup?  Well it fly almost the same flight handling as previous FPV setup but with only one differences; its cruise speed increase up to 53km/h where the stick is at 53~54% throttle travel to keep it afloat and moving forward because the extra weight it carried.   Despite flying heavy loaded nose heavy battery it is still unexplained yet mind boggling why it can flew with nose up 3 degree as indicated on 3DR telemetry screen (still tail heavy).....hmmm... but hey it flies! that matters the most. The APM did calibrated to stay flat before its maiden flight.  I've been running numerous mission flight both short and long distance and very satisfied with the fact in can handle rough and windy condition despite being overweight plus i do notice it also far stable than bigger version of UAV build which soon i will reveal this new big UAV on next chapter.  As being flown automatically (pilotless) via waypoint and autonomous mission flight the APM MINI PRO flight controller loaded with Arduplane 3.4 firmware handled very well thanks to months of tuning and much research over the internet.  When doing Aerial mapping and 3d maping mission where it needed to fly in grid formation and do tight turning to proceed to another waypoint or sometimes zig zag like movement the drifter very well during sharp cornering in manners of "bank and yank" turning without rudder assistance..no indication of stall despite turning such a tight radius almost 20~30 radius...very good indeed. However it does take longer runway to take-off  and landing due to its weight at 850 gram as oppose to normal 680gram in FPV form.

Safety issueuav drifter ultralight 23

So far no problem, just like its old sibling which flew more than 5 years its still the most floaty plane despite being small in size compare to the ratio distance it travelled.  It handled sharp cornering turn very wall to the point most normal plane will stall with such weight.  Its still the champion airframe for more than 5 years of historical long and high altitude flyer.  In UAV configuration its already proven to fly without an issues as shown in many UAV flight videos made by this plane.   Seeing is believing. 

 

 

Pros and Cons

The most contrast differences between FPV Drifter and  UAV Drifter is the weight depending what size battery it is used.
* Some Pro and Cons have been mentioned in previous FPV-Drifter Ultralight article (Click Here).

Pros:

  1. No need full control/ relax on control since plane flying automatically based on user's pre-loaded mission/waypoint.uav drifter ultralight 61
  2. Long range low altitude flight.
  3. Less FPV hardware setup used mainly for take-off and landing monitoring.

Cons:

  1. Slightly heavier at 850gram instead of average 650gram on FPV due to battery weight on UAV setup thus required extra throttle/thrust on various flight maneuvers..
  2. Need longer take-off and landing site due to increase battery weight requirement.
  3. Extra reinforcement work on the main wings spar and main landing gear.
  4. Longer learning curve to setup autonomous system and extra programming knowledge in ARDUINO code for APM hardware.

Current status & flight history

UAV Drifter #3-V5, even though born slightly 3 years younger than its FPV version of its siblings still it have accumulate 'rapid' amount of flight time and uav drifter ultralight 6more active doing long range flight in wide circuit flight path to cover bigger area than FPV version.  Its the plane i most preferred to use when i want explore uncharted area or places unreachable where it deem impossible for FPV platform to achieved.    For example: for an FPV Drifter to go further distance FPV pilot has to climb manually at higher altitude to get better video/radio connection to the pilot on the ground for it to travel further distance, but for a UAV autonomous flight on Drifter this is unnecessary as it to be flown autonomous and independent from radio or video control from the ground pilot, flew low altitude without any problem regardless distance as it is independent from any source of human contorl...robotic flight 100%.  Only both FPV and UAV plane stamina/endurance are determined by its battery capacity consumed.  Not only it capable to fly far but also does other task such as scientific aerial mapping, 3D maping and other cool things as shown in the attached video in this page.   Thus having UAV platform mean, pilot can relaxed from control and walk away from the site until the plane return back half hour later from the mission.  FPV pilot more likely getting tanned under the sun (just like what happened to me now) than UAV pilot seating in the living room watching TV or sleeping while waiting for its return by sending signal of its arrival via PC/Smartphone radio link.

Autonomous flight feature:

So what does this UAV- ES Drifter Ultralight do which makes it more special than ordinary FPV drones?  We'll there lots of things this plane can do to make pilot life easier, means you almost don't need to touch your radio controller to make the plane move or do the work...everything is robotics written all over the plane.  But to keep the words simple below are the list of thing that this plane does...what i listed is something that was already tested but i just tap 50% of its current potential.  I will discover the remaining 50% soon:

  1. uav drifter ultralight 47Autonomous flight/ Waypoint flight:  Yes, no hands flight.  It flew by itself.  I can also do auto take-off and landing too.
  2. Follow me:  You seen it before....something you saw on my multicopter project video but i don't use it much.
  3. Touch to fly:  I you have a gamepad you can use to fly it instead of using your aircraft radio controller else just point on your smart devices touch screen to command your flight.
  4. Grid flight for aerial or 3D mapping (Geospatial) flight:  I think you saw 2x samples i made on my Youtube channel.
  5. ROI inspection flight (Region Of Interest):  Just point that area you want to explore or do aerial inspection with gimbal camera and the plane do its magical works capture the ground object in all angle.
  6. Servo trigger type mission:  Something that trigger servo movement like dropping payload or activate camera, suitable for parcel delivery services on drones where it can land drop the package or touch 'n' go drop something that Google, Amazon and DHL drone are experimenting at the time of my writings.
  7. ....yet to discover..to be continue... Open source are cool!

uav drifter ultralight 52To make all this automation possible a ground computing device needed to communicate 2 ways and send command to the plane.  These are:

  • Ground telemetry data USB module (3DR radio data telemetry):  Radio receiver/transmitter used to connect to smart devices such as smartphone or notebook.via USB.  Usually this module mounted over camera tripod for good radio height dispersion.
  • Smartphone (Android), tablet or notebook:  Needed 3DR/APM Mission planner (Tower or Droid Planner for Android phones/tablet) software as user interface to link/interact with the UAV aircraft model  via Radio telemetry USB port
  • (*Optional) A gamepad or joystick devices: To connect to computing devices for extra manual control if needed instead of using aircraft model radio controller.

To sum up everything above, the pilot does nothing just sit down, relax and watch the show.  Almost the same thing what military grade drone do i guess.

uav drifter ultralight 20After flying FPV for many years standing almost stationary under the hot sun at the same time moving my whole body and arm around to obtain clear video signal by panning the video/radio antenna is pretty tiring task to accomplish.  Now i'm getting too old for that, sloppy and really doesn't have much stamina to stand around manually flying my plane while keeping eye where i'm going.  With the new UAV setup on my Drifter,  its a whole new way to more easier approach to discover the world from above via automation and robotic approach to flying.  Just setup the waypoint via my tablet, smartphone or on my PC, upload the mission, launch the plane and it will fly auto/autonomously till the end of its mission/waypoint flight without pilot intervention....i can sit back. relax and do other things while awaiting for its return. I can watch it live or view pre-recorded on board HD videos, i uav drifter ultralight 28can program the plane to do cool things like aerial mapping, 3d scan the terrains, follow me flight and other cool automated things possible by air. Planes activity can be monitor either via standard FPV style or via telemetry data wirelessly send to my portable smart devices such as my phone.   Life is good!  Ever since i have my Drifter Ultralight converted to UAV automation i manage to completely explore 95% my local places, beaches, country side and many other places deem impossible on FPV was now possible as UAV setup with almost zero "0' effort at the site.  The flights was flown perfectly stable and took many great HD footage of grounds details too thanks to great all weather onboard stabilization system.  But don't get me wrong i still do love flying FPV because cloud flying still fun thing to do when my mood comes in, UAV system play in different field so best to have both type of ES Drifter Ultralight on various occasion.  Fortunately if you checked my Drifter inventory there is a second Drifter that were built to have both of these cool feature into one.
