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: store.steampowered.com/app/41...

This made me feel much better, I have been able to fly around pretty well. But I found a tutorial to learning to fly and lesson 1 was hovering with some drills and I barely was able to do that, and I thought I just overall sucked haha. Thank you for explaining ground effect and everything in this video!

Good instructions and explanations. I trained a lot by hovering line of sight, then "walking the drone", then flying a lot in the sim FPV. I also had the impression that that flying simple race courses in a simulator after the initial stages is a good way to practice because you are somewhat forced to fly first this turn, then that turn and so on. In the beginning you crash maybe 30 times after the first gate, then you manage two gates, then more and more, then a whole lap for the first time (yayyy!), then you shout out because you crash 100 times just before finishing the third round (and the race) and then you manage your first recorded finishing time (congratulations! :-)).

Great discussion. I'm learning Acro in sims (to fly my Mobula8, which I've taken out twice and will again this weekend) and am loving it. I started in DRL and Velocidrone and when I was starting to get the hang of it and getting frustrated with the map sizes, I treated myself to Tryp. I absolutely love Tryp. The big, diverse maps have given me lots to look at and fly around and through. I was originally flying with 20 degrees, but moved to 40 degrees last night. I feel like 40 has given me a greater speed range (and/or I'm just getting better). I've been spending 30-60+ minutes a day in the sim and I see improvements every day.

Back in 1994 I started flying RC helis. I blew a fortune on spares and repairs. Thankfully the CSM flight sim arrived before I threw the towel in and within an hour of firing it up, I was hovering (although nose in would take considerably more time to master). As Joshua says, honing your skills on a sim is one of the most prudent financial decisions you'll ever make! And the RC heli / quad skillset transfers directly to flying full size helis too. 😉

This Liftoff level (Bardwell's Yard) is how I found JB. After I flew around it a few times I was like "Who's this Bardwell guy? And why does he get his own map?" I get it now. Great map too. Small but effective. Something poetic about that.

Best way I learned to hover FPV in Acro is with a shovel. Stick the shovel in the ground about 20 feet away from another vertical object (like a tree or fence post), then hover directly in front of the shovel keeping your altitude constant and keeping the other object lined up directly behind the shovel.

Hardest part of this is not being able to see forward. I have flown for 1.5 years and still can barely do this in fpv. If you need to hover for safety or something and can't land, just go a bit higher and do little dives to see down. Or you can circle

I spent 4 months practicing in the sim before my first real life flight. It took some time to get the hang of things after flying irl. Also, in the sim, you have nothing to lose but irl, you can end up in $100s in damages if you crash so I tend to be more careful. Anyway, my point is that learning in the sim was super worth it. I now dive mountains and do flips and rolls without thinking too much. I think I should start an fpv channel

Yoooo you quad racing guys are utterly crazy. You controll fine movements of drones inside a 1mm distamce of stick movement on controller. Why???? I respect all those guys who are capable of doing this and I will spend as much time as it takes to be able to fly my drone in acro mode. I dont give up and I adjust controller set up to the point when I float my drone as a feather. It wont happen in the near future but real men are up for fix difficulties :-) thanks for the video it helps a lot

I know many people don't like curved response curves; but personally, I like setting up throttle expo and mid so that at the center of the throttle stick the thrust is at about neutral buoyancy when the quad is flat, and with the expo adjusted so that there's a bit more fine-grained control around that throttle point. It does take a bit of trial and error to get it just right though.

@gus8378 3 года назад
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.

@MrStreetboy80 11 месяцев назад
Had the idea I was going into go out and flip roll and do all kind of stunts straight after practicing tons on the simulator. How I was so wrong! Drift and bounce is something you really don’t experience in simulator and the nerves of crashing makes you sketchy, the slightest of wind can cause massive drift.
@DyeFamous
@DyeFamous Год назад
No No No Joshua! The quad doesn’t fly because it shoves air molecules down into the ones below them! That’s a side effect! The blade creates a low pressure area above it, the atmospheric pressure below actually pushes up on the blade to try to equalize the pressure. It’s all Bernoulli. It happens on both sides of the blades, that’s why blades, wings, ect often are curved along their length, allowing the top surface to have slightly more length, and therefore slightly more area to create negative pressure along the top; IE Lift. Love your work bro! Couldn’t have gotten anywhere without you!
@JoshuaBardwell
@JoshuaBardwell Год назад
Conservation of momentum is also a contributor to creation of lift. You can still generate lift with a flat fan blade that is not an airfoil and has no Bernoulli Effect.

I love the Roma so much that I bought two and I just got Shark Byte two days ago and I put it on both. I really Like the Shark Byte I have never used DJI so with only analog to judge with its AMAZING. I caught myself just staring at the geese on the pond the first day and being amazed at how beautiful the view was.

Throttle management is key on a quad, use of a Eachine E010 is great to understand it, and get the necessary muscle memory. Another thing is throttle résolution: it took 3 years for the community to understand it was stupid to have 1200°/s of rates, but it seems they still haven't understood you need expo on throttle... Motor torque is huge at low Rpm, and linearly decreases with Rpm,so you need more résolution at the bottom of the stick than at the end, you need expo!

Also i wanted to ask: my drone is gliding one direction after turn, and i do turn with both sticks9 yaw, roll, then pitch with a bit more throttle, but it still want to kick me out of the turn like centrifugal force pushing. Any advice please? Or any discord or other group when i can ask some fellows for a bit of help. I'm pretty new to this. Thanks!
