How to Mount Your FC in Any Orientation (AND WHY I DO THIS SO OFTEN) 

The Babytooth with the black Flywoo motors has an XM+. I didn’t use the receiver built into the FC because it has terrible range (even for a whoop board). Fortunately, the Crazybee Lite FC has an extra UART and an extra inverted Rx pad for SBUS. The pads are small, but you’ll see them if you pull up a wiring diagram for that board. The Digital Babytooth, use Crossfire.

That would be cool, but I have a family and a job so my time is pretty fragmented. I tend to work on these projects a little at a time. I might do a live Q&A session at some point though. Is that something you would be interested in?

@@MrShutterBug certainly, I get it, have 3 of my own oldest in kindergarten.. but you have knack for creative solutions. be interesting to witness the process.

Yeah, you need to change the board offset yaw, but you also have to make sure betaflight knows which motors are in which positions. You can follow the same steps that I showed here, or if you want to try the Betaflight 4.3 RC (and matching RC configurator), then they have a new motor remapping tool that should make it even easier. Good luck. :-)

@@MrShutterBug Thanks a lot for your reply and help

When I made the video about the Nanohawk conversion, I was using stock Emuflight 0.3.3 PIDs. My usual rates are Rate = 2.1, Super Rate = 0, Expo = 0.4 (all 3 axes). My rates are pretty twitchy in the middle, but I like it because the response is almost linear all the way to the end. That makes it very predictable once you get used to it. Just my preference. Cheers!

@@MrShutterBug Thank you very much for the answer, I will try to improve my flight here. Hug from Brazil.

It looks like you could use the stock canopy and simply cut away the prop guards, but I have not tried it myself.

It has been a while since I used the speedybee app, but it looks just like the Betaflight Configurator so I would expect there to be a “board alignment” section on the “Configuration” tab. No?

If you flip the FC upside down, then you will to tell Betaflight that the board orientation was rotated by 180 degrees. Which axis depends on how you flipped it. In other words, if the same end of the FC is in the front, then it was a 180 degree roll. If the front of the FC is now in the back of the drone, then it was a 180 degree pitch. Now, if it is an AIO FC, then flipping the FC means you also need to swap the motor resources (left to right, or front to back). Make sense?

@@MrShutterBug Yes. Thank you!

To know if you got the motor mapping correct, I suggest you take the props off, plug in a battery, connect to betaflight, and use the Motors tab to spin each motor one at a time. Then you can verify that the correct motor spins and that it spins in the correct direction. I looked up the "BOOTGRACE" code. It means that you are trying to arm too soon after powering on. You have to wait a short period of time before arming, for safety. That time is controlled by CLI command "pwr_on_arm_grace" and defaults to 5 seconds. If you get "BOOTGRACE" even after waiting several seconds, then maybe your arming switch isn't mapped the way you think it is? Check it on the Modes tab in betaflight. Good luck!

@@MrShutterBug thanka for ur help. It was an error on my part. I remamped 2 motors incorectly. Luckily i have 2 of these so i looked up motor resource on the first one and mapped the motors on the second one the way the first one was assigned. Luckily they are identical and i was able to fix it that way, otherwise i may not of found the original orientation. Im thinking the bootgrace code was because i remamped 1 of the motors to a pin that gets a constant flow of power or somthing like that. Once i remapped bootgrace went away and it has worked perfect since. Other than now i have to recalibrate the fc everytime i plug in a new battery, no clue what thats about but not to big of a problem, just annoying. Thanks again for ur help and infomative videos, plus i miss living in washington and ur vids are extra special to me cause they are from my home in a way. Thanks again, i appreciate ur time and effort. Have a beautiful rest of ur day my man

Yes, you can do a 45 degree rotation the same way.

Full Emuflight CLI here: bit.ly/3ARdHHO Note that the full CLI will only work with the Nanohawk FC oriented as shown in my video. Good luck!
