- What other choices of Flight controllers that you sell and support will support the V-tail configuration with altitude hold option? Will the Pixhawk mini work? Do I have to use the Quadrino Nano FC with /GPS (RB-Lyn-826) ?
- Will 10" props work with the extended soft gear ?
- Can I use my Spectrum 6ch radio? I guess with normal servo wire hookup?
Hi daveshere,
Our guess is you are talking about the VTail400 platform ?
- The VTail is supported in MultiWii so any flight controller with MultiWii software would work. The Quadrino Nano is but we are not sure regarding PixHawk (ArduPilot).
- It’s made for 8" propellers
- Choice of Radio is related to the flight controller. The DX6 will work with the Quadrino Nano with individual channels wiring but a good alternative is the RadioLink AT9S.
Hi’, Had to put this project on the back burner for awhile. Trying again this weekend.
Yes this is the VTail 400.
I bought the Nano quadrino but it came to me with a broken case. I have a Spectrum DX6 and a KK2 controller wired in now. The quad gets off the ground but is unstable. I’m pretty sure my radio setup is wrong and I haven’t found an clear radio setup example yet. Do you have one you could suggest? I would consider re-ordering the Nano quadrino if it would help simplify this setup but I think it would just complicate things. Is there a clear setup procedure using the Nano quadrino and my Spectrum radio or any other radio system?
The “VTail” configuration is a bit tricky and the PID settings to be tweaked for the YAW which is very strong in this configuration.
It’s most probably more tuning with PID’s than the Radio as the last one only send commands and the flight controller react to that.
What do you mean “cracked” exactly ?
OK I got the quad armed and looks like all the motors are turning the correct direction now. I guess the next step is to figure out the PID thing like you say . I will start researching on line for starting points and for setup procedures . Hopefully that will be all there is to this. Sure hope so. if you have any suggestions for a P ID setting starting point or setup method, I sure would appreciate them. This may seem like a dumb question , but I was wondering if I went with the nano quadrino controller would I be able to get altitude hold with that?
Thanks
Found this . Is any good?

BrandXPD had done a lot of tests on VTail platforms and i thanks him a LOT.
Here are his files and Prop rotation Pinouts…

Hi All,
I have a request for me to put the manual that my friend did up here.
So here it is now.

Ok it’s quite confusing now with all the different configurations you can choose for VTail.
Here is the revised drawing that show different configuration on MultiWii
---- Yaw motor pins reversed —
With this mix you can’t go wrong with the kk
V tale
Mine is finally up and running with the kk2… just some minor tweaking now…had to change some very random things to get a good mix…
again my setup is a kk2 with 750 kv motors 10x4.7 props, and 3 cell battery on the 400 frame…hovers around 55% throttle…this may save some people some trouble if they have a similar setup…
So initial changes… flip all prop/motors directions to (from looking over head) M1 front left is CCW, M2 front right is CW, M3 rear left is CW, and M4 rear right is CCW.
set the kk2 to VTail… calibrate your sensors… and start with the mixer settings
CH1:
Throttle: 100
Aileron: -100
Elevator: 100
Rudder: -40
Offset: 0
CH2:
Throttle: 100
Aileron: 100
Elevator: 100
Rudder: 40
Offset: 0
CH3:
Throttle: 95
Aileron: 0
Elevator: -100
Rudder: 100
Offset: 0
CH4:
Throttle: 95
Aileron: 0
Elevator: -100
Rudder: -100

Now some rough PI values (mainly just a starting point)
Roll:
P gain:55
P limit:90
I gain:30
I limit:20
Pitch:
P gain:30
P limit:90
I gain:30
I limit:20
Yaw:
P gain:40
P limit:20
I gain:20
I limit:20
Hope this can help anyone else out there. Any suggestions or errors seen from any of the experiences users?

Views: 260The Altitude Hold can be achieved but it will be hard to tune on a VTail.
If the PID’s are perfect, there are no reason why it would not work.
VTail’s are more confortable in “forward” flight like a Tricopter flying similar to a “plane” more than a “quadcopter” style.
This section of RCgroups is ok but was based on another flight controller.
The PID’s are related to the really setup you have including the sensor/flight controller you have.
Ok right huh? LOL
Thanks
