- Practice FPV precision landings/touch & go's flying a RC EDF (electric ducted fan) jet in traffic pattern using full scale training methods with the aid of a head tracker and a reflector sight. Head tracking FPV allows the RC pilot to fly from the immersive perspective inside the cockpit to look around as if he were inside a full scale plane cockpit. Reflector sight gives pilot a precise attitude reference against the horizon and good approximation of flight path at medium speed or higher. An excellent tool for landing approach and flare.
Additionally, runway geometry (the trapezoidal shape) was used to determine whether one is too high, too low or on glide slope during final approach to landing: • Gauge FPV Landing Glid...

The Goggles and Air Unit can be substituted with your current equipment of course.
Still fantastic ! Every time!
thank you for simple pattern not maneuvers. I do not like maneuvers. it was a great video.simple and enjoyable.❤❤❤❤❤
do an HSD f16 105mm efd fpv, would be the ultimate thrill, you gus are the best
Beautiful!
Great job thx
Excellent work
enjoyed your video. thank you!1
You’ve come a LONG way. Nice landings.
Thanks cheers!
@@motionsic Hello check your email because i writed 2 times without any reply.
Bravo~
Great Job. nice flight. love your touch n go
Thank you, cheers!
I have to do this!
Very cool, now try in a stunt plane 😂
Great video, again my friend.
Working my first edf soon. Will be using this technique...
Ty for all of your help
Glad you find it helpful. Always ask am I fast or slow, high or low on approach, and adjust accordingly.
@Motionsic RC & FPV every time i land, i am looking for that information. Tail draggers are very difficult for this..
Dont stop with your content.. its very helpful
@@redwineisfine Spitfire refresher soon, thanks for the reminder😁
Inspired flying man. Great job. I'm putting together a 2.0 meter E-Flite T-28 with your gimbal and tracker stuff. EDF's will come later, lol.
Great choice for starter FPV plane, you will love it!
@@motionsicha. I just posted a question about a good starter plane. Guess I should read more of the comments.
Subscribing just now for more! Awesome experience, great job! That is definetly a goal for scale RC modeling. I had some experience with Eachine Goggles a few years ago before I stopped flying, nothing much though. I rember I dind't have the image that clear, different from the vídeo reccorded direct to the SD Card in the cam, wich had good quality. Is this quality we're watching here the same you have live from the Goggles? Any delays at all?
Yes. The live view quality is pretty much the same as this. Delay or latency is not perceptible, around 30ms according to spec.
I would love to try the feeling of flying fpv very nice landing and touch downs, do you have build video for your gear?
Working on it in a new setup…
@@motionsic hurry up
Excellent job on the landings and flying. I'm very interested in this head tracking thing but I would want an air speed indicator mainly for the landings. I have seen some but don't know if they have them for the smaller planes.
They do have airspeed sensors for FrSky and Spektrum receivers. You can program transmitter to have airspeed readout. To get airspeed on screen display in the goggles, you will need to install a flight controller as well. Something I am learning to do….
@@motionsic Yes. Read out in the goggles would be preferable. If u figure that out, plz share the info. Thx
The technology definitely exists to have the info in your goggles, or on a display inside the cockpit, either way…
Fantastic flying. Great video. I have completed my E-flight T-28 with HT gimbal (self designed and built) using a Caddx Vista nano-pro and all ground testing is complete and I'm ready to fly.
I have chosen to not add a flight controller yet but may in the future to get all the relevant telemetry in my goggles.
Questions:
-Do you use any type of flight stabilization gyros?
-You mentioned in another video that you use very tame rates for fpv flying. Would you care to elaborate a little on percentages from the manufactures recommendations for control throws?
From a happy subscriber, Thanks!
Thanks. Regarding flight stabilization, I use Fly Eagle A3Super3 on the Viper, no stabilization in the E-flite T-28.
About the rates, I always start with the linkages, by moving them to the outer most hole on the surface horn, and closest to the inner most hole on servo horn while still being able to reach manufacturers recommended throws by increasing the servo travel (end point adjustment). This provides the maximum resolution with least slop and best mechanical leverage (least torque required from servo). I then adjust the high rate and low rates based on flight experience from the cockpit. Moving from LOS to FPV flying, a good rule of thumb is from 100% to 70%, but I usually end up using even lower rates for FPV, especially for formation flying. But I switch back to to high rates for landing or low speed maneuvering.
@@motionsic Great info. Thanks for sharing your knowledge & experience. I'll play around with a third rate position to address full elevator travel for landing specifically.
-Follow up question, do you employ a flap/elevator mix? (typically used in LOS flying when flaps are deployed) I have flown a dozen aircraft but the T-28 will be the first with flaps.
@@BigDaddyI1I T-28 will need flaps to down elevator mix or it will pitch up when dropping flaps. The Viper does not need the mix.
That was awesome. You've got great skills man. Any tip on how not to stall this viper flying FPV on a maiden? I have FMS Viper 90 (non US version), and looking forward to maiden flight once I get DJI O3 Air Unit.
Best tip, is not to set your flap deflections too much. Half flaps is about 15° and full flaps is around 30°. That will give you plenty of time to flare even at idle throttle. Also setup a little reflex on aileron (half trailing edge thickness up). If you have separate channels for aileron, you can setup crow (see @TwoBrosRC for his high alpha setup).
Setup your camera so horizon evenly splits the screen on the ground. And have top of dash in view so you can intuitively use that against horizon for attitude reference. Taxi around a bit to get used to the view before maiden flight.
Use 50% throttle or more for cruise flight. Whenever throttle is lower than 50%, be ware not to raise nose above horizon. On landings, keep 25%-30% on approach until you have the runway made.
@@motionsic thank you for all the tips. That's very informative. Love your content, keep it up man. Happy flying!
Did you have a canopy on? Looks extremely clean. Love your setup btw, one day eventually...
No canopy on this one. But notice the flight time? Does not seem to negatively impact efficiency much.
Was wondering whether a polarizer filter (CPL) might help with canopy reflections. They seem to exist for small FPV cameras.
@@tobgebert the reflections don’t bother me much. The canopy is not clear enough and has too much distortions to make the the flight enjoyable.
How does the VR work with the RC plane and remote control system? Was that pre installed or did you personally do that? It’s very cool and I’m interested in it
Details in the description. A head-tracker senses head orientation and inputs the the signals to RC transmitter via trainer function which then control the gimbal onboard aircraft to move the camera. The head-tracker and gimbal are plug and play, just need two spare channels on RC transmitter and receiver.
Nice touch and goes. I missed the aerial refueling though! What was that battery voltage when you got down? I was hoping it wasn't going to go to low voltage cutoff....
Ha! I did stretch the flight a little too long, the footage even left out half a lap of the plane climbing to altitude😅. I think had 3.75V left per cell after landing. I typically finish around 3.78-3.8V.
@@motionsic Wow, that is not bad at all. My Viper 90 is not stock and won't stay up that long even doing touch and goes.
@@haroldanderson6021 I think I got lucky. Compared to other Vipers flying at the field, mine (stock) has the longest flight time🤷🏻♂️
Great landings. Is that a 70 or 80mm ? And what head tracker u using plz ?
Viper 90. Tally-Ho Head tracker: fpvdogfight.com/products/tally-ho-head-tracker
Bro the no canopy windshield fucks with me bro, I just think about the lost aerodynamics , I dont even use the landing gear on my Eachine because of this, I want to cut thru the air
Are you able to do a slip? They do come in handy from time to time.
Yes. A slip is handy if approach is too high. But I normally approach carrying a bit of power, so shallower than no power approach glide slope. So normally a slip is not needed. But for sure slip would be handy in a dead stick situation🙂
Please tell me your tally ho head tracker settings and the max settings.
this reflext sight looks good. where can I purchase it?
Working on reflex sight production now. You will be able to purchase one at fpvdogfight.com in a couple of months.
What battery, turbine and viper jet kit setup do you use? How long is the flight? Do you use any controller for stabilization and gps?
How do you record your voice and the transmitter callouts?
Cell phone.
Which flight controller are you using again?
No FC. Just gyro A3Super3: www.motionrc.com/products/eagle-a3-super-4-airplane-gyro-standard-edition-hea3s4
Hi! Watching your videos is always a treat, as I admire this innovative concept of immersive RC flight in a virtual cockpit. Your work is really remarkable and I think you are one of the pioneers in this field.
Thank you! Not content to be just an pioneer, but also an strong advocate to popularize this way to enjoy RC flying, in addition to conventional line of sight flying. One plane two uses😁
@@motionsicDo you think it would be possible to improve the cockpit view in the future..? I'm not an expert in digital technologies, but the idea would be to benefit from the head-up vision (HUD) by piloting your RC device, as if you were playing this view in a flight simulator. Although having adapted a rotating camera instead of the pilot in coordination with the virtual helmet is already a genius idea. I think referential assistance set either in the helmet view or in the cockpit of the aircraft would be a plus. Hoping that the interpretation of my vision is understandable to you..
@@motionsicNot only am I convinced that this concept of RC flight will become more popular, but also that it will be technologically predominant in the future, as it is much more immersive and precise than visual control from the ground. Perhaps there will even be enthusiasts experienced enough in this field to establish acrobatic patrols or races, as is already done with drones.
@@motionsicThank you for your excellent work, I wish you a very good continuation and success in your experiments.
@@JackD-ru2gf OSD (on screen display) flight info such as airspeed, altitude are available by installing flight controller like INAV or Arduplane. True HUD remains to be developed. I hope to have a version available in a couple of years😉
Could you do this with the dji googles 2?
Setting up Goggles 2 & O3 in another plane….
is there a way your radio can call out altitude and speed, Think that would help
Yes. I just have not implemented. Will soon!
Question would it be advantages to have the radio call out elevation and air speed to help you land without stalling.
Definitely helpful! When I didn’t have those, I had a spotter just call out altitude for the first few flights in a new plane.
Hi master
Where find reflector sight ?
Wait a couple more months, we will be producing them for sale.
@@motionsic fine
Were you using a gyro in this video?
Yes. But did not need it in low wind conditions that day.
What radio are you using?
FrSky X20S
is it possible to use gopro 12 or 11 for stabilization? it makes me dizzy
Ii use DJI O3 air unit which has electronic image stabilization built-in. See latest video.
This is soo cool ... how much would pat for this aircraft setup. ??the one u have right there
About or approximately...
$600 Viper 90mm pnp
$100 gimbal
$140 8 channel receiver
$300-1500 radio
$100 6s 50c 7000mAh battery
$150 -$300 dji air unit
$350 - $600dji fpv goggles
$125 miscellaneous products battery balance leads soldiering kit
What would be a good starter plane for FPV. I fly drones.
The 2m CZ T-28 is good. But if you don’t have space for that one. The 1.2m E-flite T-28 is a good one, too
@@motionsic thanks! That is a great plane! Do you have a video of installation and instructions for FPV?
