Hi everyone,
I'm new to San Antonio, Texas and had some questions about the area. I am newly certified under part 107. I also am a private pilot with my instrument rating and have been actively flying for a couple of years now.
I'm aware of the prohibited areas, bases and the airspaces around the city. My concern is that outside of these in the uncontrolled areas (in class G under 400'), I still see a LOT of military air traffic. Obviously I don't plan on flying my drone that high, but I would like to ensure I am being safe and considerate of other aircraft activity.
Do you recommend filing a LAANC, even when flying outside of these areas?
Are there any other rules or recommendations I should know about before I take my drone out for some aerial photography?
Thanks.
HoverAir Versa can be used like drone or like handheld gimbal pocket camera.
But what gets lost: its the first drone in long time that contains two native microphones!
So Versa is not only unique because its modular, its also the only modern DRONE with MIC!
Also 4k60, auto tracking, 10-bit H-LOG, 1/1.3 sensor, up to 17.5 stops dynamic range, 230g
After my first post here a few days ago, I played around with eCalc some more and adjusted the design parameters.
Drivetrain
I’ve now laid out the drivetrain so that, with the maximum design payload of 3 kg (including a safety margin — the actual maximum payload will be 2 kg), the aircraft has a thrust-to-weight ratio of roughly 2:1 for heavy-lift operation.
For the maximum-flight-time configuration (doubling the battery capacity + around 400 g payload, e.g. a thermal camera), the thrust-to-weight ratio is also now closer to 2:1.
Battery
I’ve also decided to build the battery using 21700 cells, specifically the Molicel INR21700-P50B. By chance, anyone has any experience with this cell?
The cells are rated for 50 A continuous discharge (60A burst), so with a 5P configuration I should theoretically be able to draw around 250 A continuously.
If I apply a conservative 20% derating due to the maximum design flight temperature of 35 °C, that gives me roughly 200 A continuous.
eCalc is estimating a maximum current of 202 A. That seems acceptable to me, but I’d really appreciate some opinions on this. Would you consider that too close to the battery’s continuous limit?
ESCs
The ESCs are also fairly close to their rated continuous current limits.
They should never actually see the maximum rated current in normal operation, but is designing this close to the continuous rating considered common practice, or would you recommend more headroom?
Motor temperature / limiting thrust
My biggest concern at the moment is the motor case temperature.
The >80 °C readings in eCalc — am I correct in assuming that these occur when the motors are operating at or close to maximum throttle?
If so, is there a way to configure ArduPilot + Pixhawk 6C so that I can limit the maximum available thrust to, say, 80% during normal operation, while still allowing 100% thrust in an emergency situation such as a motor-out scenario?
For reference, in the 3 kg payload configuration, eCalc estimates a climb rate of around 4.9 m/s. I definitely don’t need that kind of climb performance, so limiting the available thrust seems like it could be a good way to reduce motor/ESC/battery stress and temperature.
My main question is: would limiting maximum thrust primarily reduce climb rate, or could it also significantly compromise maneuverability/stability to the point of becoming unsafe or uncontrollable?
I’d be interested to hear how you guys would approach the design.
I love this snapshot of my drone i bought a few days ago!!
I've never edited photos or anything like that but some photos i see on this thread look amazing. Is there any way to edit photos to make them look a bit better even as a complete beginner? I mainly just care about editng the colors and such to make them pop more
I was flying my sky Rover S1 in my neighborhood yesterday, and as it was coming back, a hawk was chasing it. It freaked me out. I had to lower altitude and rush it back. It was weird because I’ve never had this happen before. I recently started flying and was wondering if this happens often to other people? What’s a good idea to prevent this from happening? Are birds generally attracted to drones?
Edit: the fair coordinator decided to let me turn the photos in late becasue of the print delay, so I wont have to choose. But thank you very much to everyone for your opinions, I am grateful you took time to help me.
I submitted these photos to my county fair for the phito contest, expecting 1 or maybe 2 to become finalists. All of my photos were chosen for finalists.
I ordered my prints, but found out very late that there were mechanical issues and I wont be getting my prints on time for submission. I can do same day printing, but it is much more expensive, so I want to choose the best 2 or 3 to print today. I need to turn these in tomorrow.
Can you guys help me pick the best 2-3 in here?

Hi, does anyone have experience flying in Istanbul? Was thinking about filming the Blue Mosque, but I’m afraid of the regulations. My drone is 249g so I believe I don’t need a flight license in Turkey, but the information online is ambiguous. Thanks :)
I have a bran new drone that I got as a gift, so didn't have a choice. I have a Ruko F11PRO 2. I've flown it about two hours so far. I live by the ocean in Southern California, and I'm a surfer, so I'd like to try taking some videos of my friends surfing, but the idea of flying over the water scares me.
I know the two hours is not much, and I plan on flying a lot more before I try the water. What tips or advice can you give on flying over water, other than just practice more? Are there any exercises I could try over land to better my skills for water shots?
Thanks
My son has (had) an old Holy Stone drone we got years ago--HS110 I think--and it has been, for lack of a better term, weird for a while. We learned that if you only use the provided controller, instead of a phone, it would follow your commands 90% of the time (an improvement to maybe 50% of the time if the phone was also attached). But lately it wasn't accepting inputs and would do things on its own accord. It's cheap, I didn't expect DJI level of software (I use a DJI Mini 3 for work recon), so we just had fun and enjoyed its random acts of disobedience. But last night, it left us. Maybe it decided to go to a farm upstate or something. My son was flying it and he said it's not listening to me...and he was right. The drone went up to about 100 feet and then started flying away, slowly. It went past the field beyond our property and we were trying to get it to land (I even opened the phone app) but it had its own mission. It kept flying farther and farther away and we lost sight as it crested a small hill. Hopefully it's in a better place now.
So we need another [budget] drone (under $200). I can't let him fly my work drone, so I was wondering if any newer Holy Stone drones are decent and better at not abandoning their pilots?
I came across this video on Instagram and I'm trying to understand how this flight was legally possible under Polish and EU drone regulations.
As far as I understand, flying a drone directly over an assembly of people is generally prohibited in the Open Category. In this video, however, the drone appears to be flying over a large crowd.
How was this operation legally conducted? Did the operator have a specific authorization from the Polish Civil Aviation Authority (ULC), or was there another legal basis that allowed this type of operation?
I'm particularly interested in:
I'm not claiming that the flight was illegal. I'm genuinely curious about what permissions or legal framework would allow a drone to operate over a crowd in this situation.
I misjudged how far the limb could swing out. Oops!
So my question is, is this worth repairing, and should I send it to DJI or what? I don't know how long they'd have it either. :( It looks like mainly the gimble but possible the cam or at least the connecting wiring to the cam. I haven't tried to turn it on to see if the motors work. No thanks! lol
Not my favourite day, I gotta be honest.
Thanks
Well… this was the last flight of my Avata 2 - RIP
Went out to shoot this waterfall and got a successful run with the dive first. Decided to go for another take… and that one didn't end quite as well.
100% user error - can't blame the Avata for this one.
In fact, after the first impact it fought surprisingly hard to stay in the air and almost recovered before finally going down.
The drone ended up somewhere in the forest around the waterfall.
The exact location wasn't clear, the terrain was extremely difficult to access, and eventually I had to leave without recovering it.
At least the Avata gave me one great final run before saying goodbye 🫡
Hi all. Some context: the drone is literally brand new. Opened the box 2 days ago, charged the drone and controller, connected them, and updated the firmware. Finally had the opportunity to fly it today because it was raining the last few days, so I charged everything back up to full and went outside, but nope, the drone simply refuses to connect to the RC controller.
Did the usual of turning everything off and on several times with no success. Then I tried manual pairing by holding down the drone power button for 4 seconds, but it refused to go into pairing mode (did not beep and LED was the wrong pattern). Did that about 10 times before I gave up and tried connecting it to DJI Assistant 2 (Consumer Drone Series) to try factory resetting the drone itself, but it didn’t even show up as a device on my computers (tried both Mac and Windows 11), and it isn’t the cable or my computers because the RC controller connected just fine.
Here is the full list of things I’ve tried and found:
I've spent hours trying everything I can find online, including from old Reddit posts. At this point, I suspect it’s a hardware failure of some sort in the drone, but it still baffles me as to why there’s no feature to simply factory reset the drone with a long press of the power button, which would make troubleshooting and isolating the problem source much easier.
Frankly, I’m pretty fed up with the whole thing. It hasn’t even flown once and it already seems to be broken, and all of the troubleshooting steps are ineffective.
With all of this in mind, what should I do at this point?
If it is indeed a hardware failure in the drone (motherboard, etc), would DJI provide a free replacement? I should note that the drone was actually delivered over a month ago because I bought it off Amazon during the Prime Day sale, but I only just got back from traveling. Maybe this kills any chance of a replacement.
If anyone has experienced similar problems and knows how to solve them, please let me know. Any help would be hugely appreciated. I am also happy to provide any additional details if needed. Thank you very much for your time
