Why is it so hard to hover an FPV racing drone? This video will go over all the reasons it’s hard to maintain altitude and hover, including some suggestions about how to fix it.

Thanks to Liftoff Drone Racing Simulator for building a model of my house so I can fly in the sim on days when it’s nasty outside. If you want to fly at my house, Liftoff is available on Steam at: https://store.steampowered.com/app/410340/Liftoff_FPV_Drone_Racing/

    How many inches is that

  2. Mothy on May 6, 2021 at 2:12 am

    eventually google earth will have everybody’s house mapped out so we can fly FPV

  3. Mobius-1 on May 6, 2021 at 2:12 am

    I did figure out why I’m so shitty in simulators because I’m only flying in fpv.

  4. Pat Maher on May 6, 2021 at 2:13 am

    Teaching my brother to fly, I told him.so many times, the reason you having trouble is because you too close to the ground, get it In the air before you start going all over the place….. he got it eventually….

    LOS is one thing, its a whole different animal in FPV.

    Guess who is going to have the coolest dad at career day.

  7. SparkFpv on May 6, 2021 at 2:15 am

    Is that a digital replica of Drew?

  8. VictorSeedorsky on May 6, 2021 at 2:15 am

    it is called "air cushion effect" by as far as I mean to illustrate all he said up to 2:25

  9. Mark Mullen on May 6, 2021 at 2:16 am

    Help! I have a sick race drone and a nice cine whoop, and some DJI FPV hogs, but they’re just too fast for a newbie. I need simulator time, which would require a new laptop to run. Any ideas?

  10. MeTz FPV on May 6, 2021 at 2:16 am

    Normally i watch these while my wife and i just have the TV running and i just had the most confusing time trying to understand anything through the subtitles on this vid. Honestly, try it :p

  11. Goes Boom on May 6, 2021 at 2:16 am

    My first touch of the sticks I literally lost it it flew so high😂 but thanks to your videos I had a beeper on it

  12. Trevor Philips on May 6, 2021 at 2:16 am

    I’m a newb, but is it possible to mount a second fisheye camera facing backwards (maybe) and get both signals to the goggles? The fisheye could just be a horizontal slice and not the full image and put that in a small window.

  13. Alan Hill on May 6, 2021 at 2:16 am

    Is it possible to set a aux switch to just hover and hold position?

  14. Minton Barry on May 6, 2021 at 2:18 am

    No GPS to stable ?

  15. Mircea Dogaru on May 6, 2021 at 2:18 am

    The only way I can hover (and do it quite proficient) is if I don’t tilt the camera at all. With camera tilt set for freestyle or race, not a chance.

  16. Gorillaman's Garage on May 6, 2021 at 2:18 am

    This tutorial is very good. I assume like many new comers to your channel, exploring your vast library is well worth the effort. Could you recommend several Simulators to learn on? Unless I just can not find it, do you have tutorials on learning to fly? Like this one… it really will be watched several times. Thanks.

  17. Jeff Lee on May 6, 2021 at 2:19 am

    Is the lift off the best drone sim out there? Or are there better ones?

  18. Crabtree FPV on May 6, 2021 at 2:19 am

    this is good video explaining how quads fly. too many people who fly still don’t understand. good job Joshua

  19. Mike.m mcintyre on May 6, 2021 at 2:19 am

    I love flying around your house. Lol its awesome you make better use of the layout better than me and man its hard to hit that fence gap . I feel like it would be easier in real life.

  20. David Davids on May 6, 2021 at 2:20 am

    some information. permit me to say it more concisely: get out of the ground effect zone, by immediately climbing to at least waist level.!!!!! the end. at 10:02, this is called flying in a controlled hover. the same that a heli pilot Should know how to do. it is a FUNDAMENAL rotor craft piloting Skill !!!
    so…. BEFORE trying to fly fpv….
    Practice hovering, at a constant altitude, out of ground affect, and while maintaining a tail-in orientation. (if drift is chronic, try to trim it out.) Practice flying forward and back, slowly, WHILE maintaining a constant altitude and tail-in orientation. Practice flying left/right, ditto ditto ditto ditto. Practice flying a diagonal path, ditto ditto ditto ditto (for non-fpv, THEN, do it ALL, again, flying nose-in. cheers googletranslate

  21. Adrian Garsia on May 6, 2021 at 2:21 am

    Thanks so much for this video! I am just learning to fly acro and look forward to using your drill to be able to fly more smoothly and with better control. Thanks for taking the time to help us newbies, I really appreciate your clear explanations!

  22. Corey Jackson Video on May 6, 2021 at 2:21 am

    For some reason the auto generated closed captions are in Vietnamese. Makes for an interesting read hahaha

  23. Andrew R on May 6, 2021 at 2:21 am

    Nice tip on the ratchet mechanism. I’ve got my Taranis sorted now 🙏🏻✌🏻🇬🇧

  24. Mike Kinney on May 6, 2021 at 2:23 am

    I learned something today, for sure

  25. Alloutofdonuts on May 6, 2021 at 2:25 am

    This is cool but I would still feel kinda weird about flying at your house without permission lol!

  26. geeznogoodname on May 6, 2021 at 2:26 am

    Well, if you want to hover like DJI you can’t with Betaflight! ArduPilot maybe?

  27. Roy Pettit on May 6, 2021 at 2:29 am

    Thanks for this. Are there any Betfaflight settings that will help facilitate hovering and low speed flight? I fly Cinewhoops in small spaces for "intimate" videos and not "yo-yo’ing" is a skillset I’ve not been able to master. I tried practicing with several of the top simulators and they really don’t yo-yo like real drones do, so don’t build the required muscle memory. Thanks.

  28. Kevin Mahoney on May 6, 2021 at 2:29 am

    This is good JB. I appreciate videos like this since I’m trying to learn to fly acro.

  29. slick heisenberg on May 6, 2021 at 2:30 am

    Is there a firmware that enables us to hover automatically?
    What would be required to add this feature?

  30. menne -fpv on May 6, 2021 at 2:31 am

    Wonderful, thanks!!!!

  31. Tushar Bhalerao on May 6, 2021 at 2:32 am

    this is really good video for Beginners like me

  32. Gus on May 6, 2021 at 2:33 am

    I’ve found a good way to hover and fly slowly and precisely.
    I’ve set a switch to have Angle mode, very low rates, 10 degree tilt limit, 50% scaled throttle and max expo on it.
    It’s almost perfect to maneuver it through tight spots and land it precisely. I’m able to take off and land it from my car’s roof, and reach it through the sunroof.

    I wish betaflight had a good altitude hold mode, to use with a barometer. Then it would be perfect.

  33. Blue Eye Visuals on May 6, 2021 at 2:34 am

    I leaned to ride unicycle and it’s just about as hard as fpv.

  34. Un Named Channel on May 6, 2021 at 2:35 am

    HOLY F joshua. I have never really been a fan of yours. I have not flown in or watched FPV videos in a year or more. I thought I wouls see what you are upto and you look fricken ripped man. Well done.

  35. HVM on May 6, 2021 at 2:38 am

    Propeller is rotating wing and you forget the Bernoulli’s principle part of the lift, ground effect rises pressure underside of the wing…

  36. Steve Gergetz on May 6, 2021 at 2:38 am

    Misleading title. I thought I was going to learn something about how hard hovering is with a racing drone having something to do with the SPECIFICS of RACING drones…like large camera angles (which TOTALLY screws me up when hovering), powerful super-responsive motors, or something like that…something that is peculiar to racing drones. In fact, what was addressed in this video wasn’t even specific to FPV drones, but rather all drones (minus altitude control). Instead all we really got was simply: "Why it’s so hard to hover a drone" Just sayin’

  37. Katrina LeFaye on May 6, 2021 at 2:39 am

    Wow, thank you this have been having similar problem in another sim.

  38. Drone Dome FPV on May 6, 2021 at 2:39 am

    Watching this as a newbie FPV pilot reminds me of driving instructions for a manual transmission.

  39. Limitless FPV on May 6, 2021 at 2:40 am

    2:55 #DOGE to the moon!!😁

  40. HitchSteam on May 6, 2021 at 2:41 am

    Joshua, thanks for this video!!!!! Great, could you do more. I built my first quads when DJI didn’t even exist. I am flying since so many years and I always have given up on Acro mode. I am able to fly really good in auto level. I can hover like a pro, acro mode, line of sight, but when I put on my googles I am lost! Well quads are only a tiny hobby in my life so I guess I just should practice more, but until this video I was sure that I just lack the ability. Your explanation really in detail about what is happening, helps in understanding what micro-skills there are needed. Are there also PID settings which can help newbies, so that the stick movements are more forgiving? Thanks a lot for enriching the world around this hobby!!

  41. Manny Martinez on May 6, 2021 at 2:41 am

    I knew that was your house, freakn awesome with the hole on the fence you always fly through.

  42. KTM BIKES on May 6, 2021 at 2:44 am

    You are incorrect about how ground effect works, its not air pushing down like everybody asumes and thats not how any aircraft works. The air under the blades is applying more force than the lighter air flowing over the props. A light aircraft has a prop pulling forward and rotors pull up, both wings and props are the same. You float in ground effect because the ground disrupts the air and makes the rotors more efficent increasing lift, your not pushing air down.

  43. gebruikersaccount123 on May 6, 2021 at 2:45 am

    haha, funny @ the end 🙂 Nice and thanks for this learning advice.Maybe good to add some advice for how to set up the simulator (which settings, which drone)?

  44. william Groner on May 6, 2021 at 2:46 am

    Those of us who fly real helicopters understand this all too well, and trained for it. HIGE and HOGE. Thats why at times a helicopter cannot hover at say, 10,000 ft. density altitude out of ground effect, but can hover up to 12,500 ft density altitude in ground effect. When taking off in this condition you wont have enough power to take off vertically, but if you sat in ground effect and moved forward until you reach Effective Translational lift speed, then you dont need maximum power anymore and you can just fly up and out of ground effect.

  45. LeRainbow FPV on May 6, 2021 at 2:47 am

    2:03 basically saying propeller/battery combination has a specific impulse just like a rocket engine? haha would be funny if HQProps would list m*v as a prop spec.

  46. ROBERT A MOESER on May 6, 2021 at 2:53 am

    In physics the thrust vector would be drawn in the direction of the force, so up, not down, and forward not back. Like you are being pulled, not pushed.

    Physics helps immensely unless, like me, you overthink it. But a diagram of all forces thrust, gravity and air drag can cut right to what’s actually going on in, say, a power loop.

  47. Mike.m mcintyre on May 6, 2021 at 2:55 am

    Whats your favorite quad in lift off?

  48. Charlie on May 6, 2021 at 2:59 am

    The general public: hurr-durr I don’t want drones spying on my property
    Joshua: Hey guys look here’s a 3D model of my house so you can fly around all you want!!

    Hahha good stuff man, I really enjoyed the video

  49. Axel Becker on May 6, 2021 at 3:02 am

    Hi Joshua. Great video for a beginner like me. I don´t want to invest in all the stuff just jet. Can you recommend a cheap controller for practicing in the sim? Later on I´d like to fly a cinewhoop for film making. I´m not going for hardcore acro or racing.
    Thanks in advance!

  50. Gunsnwater on May 6, 2021 at 3:05 am

    The props are the wings. They are airfoils. The air is split over the top and bottom of the blades. The surface area is greater on the top so the air must move faster. This creates a difference in air pressure called lift. It sucks the quad up.it doesnt push from the bottom except in ground efect.
