Tips for antenna mounting (the receiver ones) if you put the antennas under neath the zip-tie, then they will have a much less chance of getting chopped with the propellers. Also if you use thicker zip ties, they will have a less chance of getting bent up into the propellers.
This series is fantastic. Thanks to you and RR for making it happen. Joshua, don't you have a video that covers the two sets (3,2) of beeps when powering up the quad?
JB; Love this build series. Thanks. Question: I've had now 3 R-XSR receivers. All 3; that tiny little bind button has slid off the board. Causing me to have to short the tiny traces to get it to bind. Super difficult, but does work! Tips?
I'm wondering why it´s not possible to wire sbus and smartbus to the same UART, e.g. to RX4 and TX4. The KAKUTE F7 manual like all other FC manuals tell to wire these buses to TX and RX of different UARTs. Why? What is the technical explanation for this. Also, is there a reason why you didn't use the fport solution with one wire only? Is fport still not ready to be fully trusted? By the way, I love your videos. It made me confident to build my own freestyle quad and to enter the FPV hobby. I just finished successfully my LOS maiden flight today. Now I just need to practice, practice and practice to be able to pull all those stunts you guys (and gals) do. :-D
The same UART cannot be used for two different functions. Well, technically it can, but the functions have to run at the same baud rate. SmartPort telemetry and SBUS control do not operate at the same baud rate. Therefore they cannot share the TX and RX pads of the same UART. Use FPort if you want to get telemetry and control on the same UART.
What do you do if you want to use redundant receivers and what does that actually accomplish? Also, do the redundant receivers have to be the same, or can one be the xsr and one be a x4rsb?
Redundant receivers means that if one failsafes, then the other one will take over. This is most useful if you are building a large model where parts of the model might shadow one receiver, but the other receiver would have clear line of sight to the transmitter. On a mini quad I don't think there is much advantage. Let's say you have two redundant FrSky receivers? Why would one failsafe but not the other?
Joshua Bardwell thank you. I guess that makes me think of the question... couldn’t one frSky fail safe just because it is out of line of sight and the other would then take over even if its also frSky? I’m brand new to all this... so I apologize if my question doesn’t make sense. But I have just bought a taranis qx7 for Christmas and I literally got the battery for it today... now for some simulator time!!!! And that brings me to my next question... I have the Rx and a battery (and charger) and a usb cable... Is there any thing else I need to do to start on velocidrone other than have a capable computer?
Does it really matte if I use a temperature controlled soldering iron? I have a soldering gun, and it heats up to 1135 F as its maximum. I havent started making this build but I've been watching all of the previous episodes. Also how does the camera work? Do we connect it through phone to see it? And is the video of the drone flying at the end the drone that we are making? Sorry for the questions. I'm new and curious.
A temperature controlled soldering iron will give much, much better results. Your iron heats up to over 600 C which is way, way, WAY too hot even for me, and I have been accused of running my iron too hot. The camera connects to the video transmitter which transmits signal to the goggles.
You can't use T1 and R1 for FrSky telemetry and control. They have to be separate UARTS. If you use the FPort firmware on the receiver, you use a single UART for both functions.
Just to confirm, you used 2 different uarts for the receiver tx4 and rx6, I haven't been able to get telemetry with the rxsr, I can't wait to see the config video.
Yes. FrSky receiver uses TX for SmartPort telemetry and RX for SBUS control. They are NOT the same UART. They are separate UARTs. You can get around this by using FPort firmware on your receiver. FPort uses the same UART for telemetry and control. But I didn't want to make people flash FPort for this beginner build series.
I use thread locker sometimes but usually I just make sure my screws are tight. I'm constantly working on my quads so thread locker is more of an annoyance than a help sometimes.
Yes this build works with a flysky receiver. There is a link in the "reciever" video description containing Philipp Seidel wiring diagrams for all major common receiver types.
Hi! Joshua Bardwell. I just went through your video series and few other videos on how to make a drone (build a drone under $99). I had a trouble finding your Bardwell's Budget Build Kit on internet as it's out of stock. So can I use the the drone parts used in this video bit.ly/2RlAnZF or bit.ly/2OXi1kR to build my drone and follow your instructions on setting up the receiver and transmitter, and all the other stuff you have done on your computer? In short I just want to use different drone parts (not your Bardwell's Budget Build Kit ) and follow your instructions on setting up the drone on computer. Please guide me with this. Also Kindly check the video links, there the person has missed out to setup the transmitter so i am confused what to do. Will this work? Thanking you in anticipation
If you use different parts, then instructions will not be exactly the same, but you may be able to follow along and adjust the instructions for your equipment.
I'VE UPDATED THE BUILD. bit.ly/2ZG6skz BUILD THIS ONE INSTEAD.

This is really helpful, thank you!
Sorry if this is a dumb question, I'm new to all this lol but do we buy the receiver separately or is it included with something else?
The receiver is purchased separately.
Any updates for cleaning up those twisted up black wires? Or maybe a part number for the shorter wires?
It comes with the ESC.

Be more careful when pressing the bind button.

Any reason to use those specific R and T pads on the FC? Isn't it just possible to use T1 and R1 and select them through the betaflight software?
You can't use T1 and R1 for FrSky telemetry and control. They have to be separate UARTS. If you use the FPort firmware on the receiver, you use a single UART for both functions.
Just to confirm, you used 2 different uarts for the receiver tx4 and rx6, I haven't been able to get telemetry with the rxsr, I can't wait to see the config video.

FPort uses the same UART for telemetry and control. But I didn't want to make people flash FPort for this beginner build series.
Are you not a fan of Loctite? Are you disassembling/assembling your quads often enough to be ensuring that all screws are tight? Just curious...
I use thread locker sometimes but usually I just make sure my screws are tight. I'm constantly working on my quads so thread locker is more of an annoyance than a help sometimes.
Hi Joshua, can a Graupner rx with SUMD be wired to the UART of this FC? (it's not inverted)
Yes, Betaflight supports SUMD. However there are also several Graupner compatible receivers that output SBUS if you like.
Will i be able to install my flysky recievers using this vidio i just bought a nirvana
Yes this build works with a flysky receiver. There is a link in the "reciever" video description containing Philipp Seidel wiring diagrams for all major common receiver types.
