Try this, i downloaded the file new from WhiteSpy and added the config.

Awesome! Thanks, one other question, what do you know about s.bus? Check this out, youtu.be/of1vFu1gNC0 this is from the sketch I posted (not yours, I haven’t uploaded it yet) but it’s acting crazy.
I opened the one you posted and already commented the sbus portion, but I’m wondering if it’s going to act crazy like in the video. Any ideas? When looking at the one I posted did you happen to see anything I did wrong?
Thanks as always,
James
I have started fresh pretty fast because i didn’t know which changes you did.
What are you using, a spektrum receiver ?
I have the FrSky Taranis X9D with the X8R receiver. so I was going to use the sbus capability to get 16 channels.
I also have the blacked pro Ez3.0 board and the magnometer is not on the main board but on the board with the GPS. I’ve been trying to determine if that requires commenting something as well…
so my goals would be sbus, newvtail.h and making sure the magnometer works…
the one I posted the sbus seemed to be working but was crazy all over the place… but the compass seemed to be working right.
My latest…
…a little bit further. …
Is calibrating the T-Motor ESCs different from the guide online? It’s late but I’ll do a video tomorrow
Ok, i was away a bit yesterday.
Where are you at ? What’s not working and what is ?
The T-Motor does have a slightly different “Sound” but it still the same process.
Best way to calibrate the ESC’s is with MultiWii but it involve loading a “Not Flyable” version first and back the real config.
What it does is the calibration by it’s own on each ESC’s at the same time and with the exact scaling.
spinning motors! weeeee
so I did my first flight. very touchy in acro, switched to horizon and still going to get some getting used to… now the reading and fine tuning… I’d like to thank you for the help too!
Although I do have another question… so I did the Bluetooth and usb hooked up at the same time thing in my bumbling through setup, so now my phone won’t connect to the Bluetooth… It did initially… but no more… it sees it, it pairs… and the app even says it’ll connect but then all hell breaks loose… I keep getting these messages saying 0 data transferred and all these negative numbers… and if I switch over to see if it really is connected as the app is saying and it’s not. Anyway, I know I read something about this a while back… but I can’t find it now. You know anything about the Multiwii and Bluetooth interface?
Once again, thanks for the help.
This is the build log I have been keeping if you want some entertainment.

It should work, the Bluetooth with MultiWii is very easy.
Make sure you have the TX and RX inverted from the flight controller and the Bluetooth module.
Have you loaded the PID file or you started from scratch ?
Ya, I loaded one for the 400 I think. The laptop is at home.
Tried unpairing and repairing the Bluetooth with no luck. Confirmed RX -> TX and TX -> RX. But phone still won’t connect to it…
So which flight mode is the most stable? I set up two switches, one to arm it and the other is a 3 position switch with acro, angle and horizon. I was thinking horizon was the most stable? Is that true?
Did you try to reboot your phone ?
What’s weird is that it worked at one point.
The “Angle” mode is not really used anymore, Horizon will be the stable mode.
You can look on P.18 of Lynxmotion - MultiWi Software Configuration v1.1.pdf[font=Verdana][size=1][highlight=#ffffff] [/highlight][/size][/font]there is a description of modes.
I’ll mess around with the Bluetooth tomorrow night, gonna take a night off, been at it hard and heavy all holiday… here she is in her awesomeness. This is in horizon mode. Gonna have to wait till this weekend to take her out and get a little crazy…
Hey Eric, did you guys ever try 12" props on these T-Motors? The chart you guys have with those motors shows 12’s to be the most efficient, plus it looks like they would clear it… so I was just curious… I thought I might try some.
Hello,
I just finished putting together my VTail 400 quadcopter. I used the T-Motor combo kit with a Multiwii mega FC. I just finished the first test flight and noticed a couple of things. I have only done minimal tuning so far and I increased the roll/pitch rates (~0.15) and yaw to ~0.3. First, throttle response was kind of sluggish. Punching the throttle to a 100% resulted in a relatively slow climb. Second, even thought the VTail seemed stable in flight (horizon mode) I ran into death oscillations a couple of times. Reduce P’s? There were also some tail oscillations (caused no problem). Any ideas how to improve the throttle response?
Thanks,
Steve
I too am in the testing phase of my 500 build. I too have some questions. (see video)
…and the ccw prop adapters are on order, should be here tomorrow.
I did include the “newvtail.h” and loaded the 400 vtail.mwi file from Lynxmotion. Other than that I haven’t touched PIDs.
I’m still using the default Multiwii PID values. Will use the the PIDs from 400 vtail.mwi file for the next flight tests.
Here it is with the default PID settings (rates only changed):
I’m estimating that the thrust to weight ratio for the VTail 400 T-Motor combo kit is around 1.7 (3S battery). Is this by design? This may explain why the acceleration is somewhat sluggish.

I have the 500 VTail T-Motor with flip controller, tried loading the newest file/setch for it. the load fails mesg. is checksum 3.3v this is the 5v flip board per your instructions. would this problem be in the file or the board name?
