    Cheapest motor/prop configuration for the greatest thrust?

    Speed for any vehicle can be calculated with theoretical numbers but testing with your vehicle is the best way to actually know. Long story short there are lots of sources of force acting against the vehicle especially once you start driving it, there is friction with the ground or bearings and...

    Replacement Screws for HolyStone HS510 propeller/motor

    Without digital calipers to check the diameter of the thread it is hard to guess. In general the metric screws are classified by that thread diameter an m3 screw will fit into a 3mm hole (has just under 3mm diameter thread). Most quads use m3 but those look like could be m2 or m2.5 even sort...

    Adding audio to video

    Yah not entirely sure what's being asked if you have a non corrupt video file in some format you can use ffmpeg or if on windows check out winff to convert the file to something that can be used in a video editor... otherwise other option is upload to YouTube let them convert to webm or vp6 or...

    GPS - a simple and straightforward explanation of it

    Yah the short answer is as Dugdog said there, it is based on satellites, time of flight of a signal (knowing those move at the speed of light and that is mostly known/fixed) it can essentially triangulate the position by getting a bunch of signals sent to the quad with known positions of the...

    4 kwads at once?

    oh also also, my day job I've been working on IoT things for like 6 months and turns out a lot of those things can use STM32F4 or similar chips at the core of them (usually with some supporting wifi hardware) so another way to go is use AWS IoT platform add all your quads to a greengrass group...

    4 kwads at once?

    Hey @Dugdog47 I've been asked about this before by friends so have thought about it a bit too. Long story short I think the best way to go about this would be to have all the quads GPS controlled actually because without the known position for all the quads they are going to be likely to drift...

    Please Help - can't get BetaFPV and TinyHawk2 working

    Hah yah got about half way through before realized what our new bud here was saying :D It is confusing so don't fault you for the confusion but yah you need to hook up the USB on the quad (it is basically right behind/below the camera on the tiny hawk 2). Once you have the quad flight...

    Weight and Battery Advice

    Hiya welcome to the forum! You mean a 1.8Ah battery? Also suggest checking out ecalc.ch when building totally custom or partially custom stuff can be very useful to verify your prop size etc. is going to work out. Hard to guess what to change without running numbers there but from looking...

    Emotion Mavic (Eachine E58) will turn on, but propellers won't start

    Yah super unlikely to be simultaneous failure it's just something with the receiver input or the flight controller almost definitely (control link related or otherwise software/firmware issue on flight controller it sounds like). Brushless motors last a very very long time any sort of brushed...

    Emotion Mavic (Eachine E58) will turn on, but propellers won't start

    Hiya so no experience with that particular model. In general the toy grade quads will run off 1S or 2S battery a 1S battery is 1 lithium cell which has a max charged voltage of 4.2V and a minimum voltage usually at 3.0V but when pulling power from the battery the voltage dips so most pilots...

    Soundtrack.

    There are lots of options. If you have a pretty good computer can use kdenlive on Linux or windows movie maker if on windows I think there is one built into Mac os as well. Even the most basic video editor will allow you to replace the audio, with kdenlive or Adobe premiere or something else...

    Drone behaving strangely ?

    Sorry kinda useless here :D I haven't used those PWM output receivers with an FC so honestly could not tell you clearly on that one either, in general I've got Spektrum or FrSky receivers that send all the control signals on a single wire (SBUS or otherwise). I have only used ones that output...

    Anyone in SW Ireland

    Hey yah just noticed questions about turtle mode. Basically the FC needs to have firmware that supports it but think back to somewhere in the 3.x or any 4.x betaflight version will have "crash over flip mode" if you enable expert toggle and go to the modes tab I think. Only other requirement is...

    Hubsan 501s minor problem.

    Pretty sure FAT32 is limited to 4GB file sizes unless using some extension on the base filesystem: https://www.ntfs.com/ntfs_vs_fat.htm no idea what a 1.3GB limit would be imposed by really could just be a corrupt SD card sometimes they are DOA or otherwise start to fail after too many...

    Can you restore an FC to factory settings ??

    It appears the Naze32 Rev6 boards use a STM32F something chip so you could see about using a st-link to be an alternative way to connect to the chip if the normal USB connection or bootloader gets corrupted, with st-link and the st-link software you can get a connection to the chip through the...

    Can you restore an FC to factory settings ??

    I'm not entirely an expert but maybe intermediate knowledge with programming embedded devices or MCUs, it sounds to me like the bootloader is having issues (there is usually a partition called the bootloader partition that is at the beginning of the flash memory the MCU starts up with and that...
