Would someone tell me what I'm doing wrong here? After creating 6 flightmodes in LibrePilot and programming the switches as shown below my 250 QC with a Revo will no longer arm unless I change it to always armed. When I do that it automatically throttles up.
Channel 5 & 6 for the 6 flight modes, channel 7 for a second throttle safety and channel 8 I'm not sure what I'm using it for yet. I think I'm going to use it for failsafe return home.
Aux Channels
Channel 5 = Sw C+D
Channel 6 = Sw D
Channel 7 = Sw A
Channel 8 = Sw B
Switch assignments
Fly mode = Sw D
Normal
Idle mode = Sw B
Normal
Thro. Hold = Sw A
Off
Throttle hold
Hold = Off
Value = 50%

If it was working before, then the answer is that your arming stick positions (or arming switch position, etc.) is not what it was before.
You can read what your transmitter sticks are saying by looking at the Input page. Make sure you turn off "always armed" first.
For arming with right yaw, the throttle must be zero (not even 5%) and yaw must be 90% to 100% rightward IIRC. Your mixes threw that off. Find out where the mixes are making a problem, or re-run the transmitter wizard. Be aware that the transmitter wizard can't do miracles though... :)

250 Quad with a Revolution running LibrePilot 16.09. I changed the FS-i6a receiver using PWM to a FS-ia6b using PPM. Then I configured the following on a FS-i6 transmitter with 10 channel firmware: switch A (ch7-Accessory1) as a throttle safety, switch B (ch8-Accessory 2) for arming, switch C & D (ch5) for FC modes and D (ch6) to switch btw FC 1-3 & FC 4-6. Arming is set to Acc2 in configuration tab.
All switches appear to be work on the RC settings on the configure tab but the quad won't arm. The input light on the sys health panel lights up yellow. Failsafe is unchecked on the failsafe settings tab.
I was hoping someone might take a look at my uav file to see if you can spot where the problem might be.
I think next time I'll defiantly do one change at a time!!!

Cannot help here... all the files you posted are empty.
Yellow input alarm mean the receiver is not powered or some input channel you configured is missing and finally board is in failsafe state.
Re-run transmitter wizard.
****************
There is multiples issues in your configuration that highlight you did the config by hand.
- Accessory2 has min/max = 0 and should be used for arming, this cannot work...
- Collective is PPM input type without channel assigned and collective is not used here.
All the above will be fixed after rerun the Transmitter Wizard.
Why you mapped the 3 Accessory to outputs, any reason ?
Outputs are also set with min/max = 1000/1001 (no range)
-
I think it fixed everything but still doesn't arm, please see new UAV file. Also found that I had transmitter failsafe turned on. Fixed that and now the input light is green! Still not arming though.
Modified, no need to quote a post found just above.
-
Accessory1 still wrong for arming.
Did you really redo the Transmitter Wizard ?
Accessory1 to Accessory3 are not fine.

I did run transmitter wizard and that was the result. Please advise how to correct the accessory's? Should I try running the wizard again?
-
Try the Manual calibration.
Click the "Start Manual calibration" button
Move all sticks and switches
Click the same button called "Stop Manual calibration" button
Try moving the min value around 1000 by hand
-
Looking again at your latest config file, using the Transmitter Wizard the Accessory1 (ch7) and Accessory2 (ch8) cannot be detected with a min/max value set to 0.
So redo the transmitter wizard and save at end, this will remove any channel not valid or not detected.

Changing the min on all accessories to 1000 did the trick!
I can finally arm my Quad again!!!
Thank you very much for your assistance.
I can't wait to try it out tomorrow.

I'm having a different problem now. It works good connected to LibrePilot, but when I brought it out doors not so much. It goes from 0-50% throttle with nothing between.
So I connected to LibrePilot and ran vehicle wizard and it work good. Then to make sure I went back down to 0 throttle & when I gave it throttle I'm back to 0-50%. No if I disarm and arm again its better, but again if I go back down to 0 same thing all over again?
Any ideas?
-
Revert the Stabilization > Basic > "Zero integral when Throttle is low" (bottom) to Checked, as default.

That fixed that problem, no more 0-50% throttle! I noticed though one of my motors doesn't always want to start. If I stop and try again it does but when I try lifting off it wants to flip backwards? Tried trimming my transmitter then it wants to flip to the right?
Quad weight is balance at center point. Any ideas?
-
Never ever change the transmitter trims from where they were when you ran transmitter wizard. If Attitude mode drifts, use Attitude -> RotateVirtual to adjust for the drift.
Always take off from level ground with a quick jump into the air with controls neutral (never "help" it) instead of slow throttle increase.
-
Haven't been able to try your suggestion yet outside but I do have a question. Testing in my shop if I hesitate with the throttle it will increase slowly all by itself. Any idea why this would happen?
-
That is normal and doesn't happen when flying.
"I" term windup. It is not perfectly level, so it tries harder and harder to make it level by increasing some motors. When actually taking off, do not let it wind up before liftoff. Take off immediately with a quick jump to knee high with sticks neutral. You can practice this starting with not enough power and try more and more power till it comes up but not too much.
-
Having a problem with quad flipping backwards or to the left on takeoff. I went back to vehicle setup. During the finding neutral on the motors I noticed the aft-left motor can bearly be heard. Sounds nothing like the others. When I completed the setup, that motor does not start when the others do. Would this be a problem with the motor or the ECS or both?
-
This to start with
https://librepilot.atlassian.net/wiki/display/LPDOC/ESC+Calibration
Then use the default (enabled) for Stabilization->"ZeroTheIntegral". Why do so many newbies wind up with this set to the non-default value of "disabled"?
Take off quickly after starting motors. Jump up to knee high.
Don't "help it" while taking off. Leave the sticks in the middle!
Don't take off from the side of a hill.
