Hi there, I purchased the Hunter V Tail 500 kit with Quadrino Nano and am using a Spektrum AR8010T receiver along with a Spektrum DX8 transmitter. I got everything together then set up the FCT and flashed it to the Quadrino then went on to WinGUI and had no problems calibrating ACC and Mag but when I went to the Flight deck tab I found that I couldn’t change the values in the receiver information box with my joysticks. I can change the values of AUX1 and AUX3 with switches but nothing with the joystick and AUX2. I went back to FCT and changed Rx protocol from Spektrum to StandardPCM and flashed it to the Nano but no change. Tried setting the end points on the transmitter but no change with that either. The transmitter and receiver are binded btw. I checked and rechecked my wiring but everything looks good to me. I haven’t tried to calibrate the motors yet because I thought the issue of not being able to change the throttle values etc in the software needs to be resolved first, but maybe I should try it to make sure the receiver is working properly? Sending some pictures, maybe that will help. Any suggestions? Thanks much.
Hi rschlenk,
Can you post a better image that show your wiring to the receiver ?
I’m unsure if the wiring is done right or not.
You should be using “StandardPCM” as receiver in the FCT not Spektrum since you are not using a “Satellite” receiver.
I’m sorry but i can’t see any of the bottom connections on those pictures.
Also, make sure you are in “plane” mode on your transmitter.
I’ll try to send some better pictures later today now that I know what you need. I started off in “plane mode”, that is it showed an image of a plane and “acro” on the transmitter display. I changed it to “quadcopter” but that didn’t work either.
Your issue is probably a mix of Wiring and Setup in the FCT.
It’s important to “flash” the board after each changes otherwise the board will not be updated.
Looking at the drawing on the Receiver.
The signals are all toward the middle of the receiver so the top row need to be inverted.
So you’re saying I should connect the wires of the first row to the bottom row of pins (of the first row)?
Here is a picture of what we understand.
The signals are toward the middle of the receiver on both row.
Ok got it. I think I tried that already but I’ll try it again to be sure. Maybe I didn’t have a setting right. Could you give me tips for settings in the FCT for a V Tail 500 such as min and max throttle values, custom mix (normal?), set fail safe to enable or not since the spectrum system has it’s own fail safe, etc. Thanks
Maybe you tested this when the flight controller was in “spektrum” mode.
You can test the standard values of throttle, usually they are fine. This is linked to the hardware (ESC) mostly.
As for the Failsafe it’s a good practice to let it ON as it will help in case of lost signal.
You were right, I connected the wires as you suggested and that did the trick. Thanks very much. I calibrated the ESC’s with the firmware on the Nano then did a Arm Test. Everything seems good. Next weekend I’ll balance the propellers and take it out for a test run! Thanks again!
Ok I will. I was wondering about that. Thanks
Could you tell me if I installed the propeller correctly? First time out a nut came loose and flew off. The plastic insert/donut or whatever it’s called that came with the props (4 different sizes) seems a little loose on the motor shaft. The other inserts are either too small or too large, should the prop be really snug when you put it on the motor shaft?
The inserts should avoid having the propeller Off-Center which will cause vibrations.
As for the “nuts” you usually take either the standard nut or the dome-shape nut that’s your choice. However using both can “lock” them in place making it harder to un-screw in flight.
Hello again. Just had some questions:
- When MAG mode is enabled and the V Tail is on the ground should the props be turning even with no throttle? Mine do.
- I have MAG mode assigned to a knob on my transmitter where MAG is enabled when the knob is turned to the midway point (M), should I instead assign MAG to a regular toggle switch?
I’ve been having a motor stop turning in flight causing the coptor to crash and it seems like I started to have this problem when I started using MAG mode. When I have time I will more thoroughly check the wiring connections but in the meantime I wanted to find out if the way I have MAG set up could be causing the problem.
I can’t see the link between the MAG mode and the issues.
What’s your setting of “Motor Stop” in FCT as shown in the manual HERE.
If you have it “checked” the motor will not spin when you Arm the copter but if it’s “not checked” they will turn at the “Minimum Throttle” value.
I’m always using the “not checked” option personally as it show visually that your copter is armed and potentially dangerous if you lift the throttle.
Using a Knob is not a problem, it will be the same signal of around 1500 if you center it.
However it makes things a bit harder to set in flight.
Make sure you did the ESC calibration otherwise the flight controller could send a low command which shut off the motors.
