"You are absolutely right. I realized a few minutes ago that I'm an idiot and that the Pixhawk is still trying to get level even on the bench so this test is worthless. So I went back out for a test flight and I have improved the situation…"

Michael Burmeister replied to Bob Smith's discussion RCOUT mismatch in static test - HELP
"On the bench the motor will all spin up differently because it is using the IMU to determine how the copter is positioned and will spin up based on level. Looking at the output it seems that maybe the copter is not balanced because motors 2, 4, and…"

RCOUT mismatch in static test - HELP

I posted this problem on RCGROUPS but on further investigation I a think my problem is in some setup I missed in mission planner.I have a new X6 based on Pixhawk. The salient features are:- Tarot 5008 motors- 1855 CF props- Pixhawk - Multi-pal 40A OPTO ESCI was getting a Motor imbalance warning in flight that appeared to be getting worse.       Test: Motor Balance = FAIL - Motor channel averages = [1380, 1586, 1353, 1580, 1371, 1598]       Average motor output = 1478       Difference between…See More

"That's what I thought. I just got back inside from re-doing the AT on Pitch and Roll only. It completed and gave me a reassuring message on the Taranis. The PIDs have been saved.  I'll do the Yaw tomorrow, weather permitting. Thanks…"

Andre K. replied to Bob Smith's discussion Autotune not updating params.
"Unless it completes all selected axis, it's not considered complete, and will not save. Choose few axis at a time, or if symmetrical, only roll and yaw, then copy to pitch."

Autotune not updating params.

I have a new build and ran autotune today. I have the tune mode AUTOTUNE_AXIS = 7I ran Pitch and roll but I had to land before yaw was complete. I left the channel 7 switch which activated auto tune in the "ON" position until I landed and disarmed.The ATC_xxx parameters are the same before and after this flight.I am sure I have missed a detail in this process. My questions:1) If it has to stop the 3 axis AT will it store the completed ones or just ignore all its good work? Dumb if it does but a…See More

Storm32 configuration help needed

Firstly let me say that I know what I am doing is perverse but I got here by accident. I feel like I'm close but the STORM32 setup is proving tricky.My gimbal:It's actually a 2 axis Tarot servo gimbal but I can't control continuous servos from a Pixhawk so I thought I would modify it to a brushless gimbal. I had a couple of GBM5010 from Rctimer sitting around. You will see the result in the attached snap shots. Also attached is the config file .I am using firmware v0.90 and the board is…See More

Tarot 2D full size gimbal with continuous servo motors

I have a new X6 Tarot build and so far the early flights are going well. I now look at the gimball and camera mount.I should first clarify that my goal is aerial still photography with a full size Canon camera. That means that stable video is out of scope. Tilt control is and stabilization is a nice to have (2D).While I was researching my purchases I came upon the Tarot Rabbit Invincible 2D…See More

X6 new build battery discharge question

This is a new problem for me but I am sure the answer lies in the physics of batteries and that one of you can explain it to me.I have a new X6 build using Pixhawk I have Taranis telemetry working. I have had a few test flights to see how things were going and everything looked to be as it should be. Then I was ready for the hover test and flight duration test. I have noted on the short flights that the hover current was about 35A which agreed pretty well with eCalc. When I tried the longer…See More

Tarot X6 build 1855 folding propellers

I am close to the fun bit of my new build but am dismayed that I cannot find any folding propeller to fit the design at 1855. The thought of bolting props onto the beast every time I need to launch does not excite me.I have read some bad things about quick release adapters. Anyone have experience with these above 15 inches? My flying will be sedate and about still photography in case that's a consideration.ThnanksSee More

When is a gimbal not a gimbal?

I am building a hex machine to carry a small DSLR for still photography. I have been working on a 3D gimbal and things are going well. In an idle moment the thought struck me "Why do I need a gimbal for still photography?".Surely I need a camera mount with a tilt (y axis control) as one would have with a 2D gimbal, but why the complexity of stabilization? I am trying to build a flying tripod and although I get that the FPV through the DSLR will not be beautifully smooth a still shot should be…See More
