How to use SITL simulated vehicle to test a real antenna tracker ?

Started this discussion. Last reply by Jakub Oller May 16. 4 Replies

Hello,I would like to test a real antenna tracker, driven by a Pixhawk and the antenna tracker firmware,  which is setup "in the middle" : on one side the antenna tracker is linked via 3DR radio to the vehicle, on the other side, it is linked to a…Continue

What is the status of 3DR radios?

Started this discussion. Last reply by Art Feb 3. 5 Replies

A user reported on this forum a 3DR representative announcing 3DR is stopping the 433 and 915 radios. I assume this is incorrect information or is it? Can a 3DR official give the real status?If 3DR really stops the radios, what could be reliable…Continue

190 size FPV racer build & review from GEP

Hi,A 190 size FPV racer kit review from the GEP brand (so called ZX5 model). What's different about the previous FPV racers build I did before is a X frame while my former builds were always made with a classical H frame.X frames have an advantage over H frames in that they are more symetrical (useful in FPV racing) and they twist much less along the central beam : that is a better Yaw control in racing.Issue though with an X frame in a small FPV racer is the lack of room to setup all of the…See More

This is a hardware review of an interesting product for FPV racers. I do not know for how long it exists but I could not find any other reviews on youtube.

This product consists in an integration of mutliple components you would otherwise need to solder and assemble together with lots of wiring, thus saving weight and making a…

Didn't want to say this in the crowd.  But I think mass distribution has a bearing on the PIDs as does distance from the respective axis.

Example:  Say there is a rectangular cubic battery pointing fore and aft at CG on a symmetric quad copter.  Say the rotors are 20 cm from their axis and the battery is 10cm x 2 cm.

o The torque factor exerted in pitch over the battery would be 20/(10/4) = 8 to 1

o The torque factor exerted in roll over the battery would be 20/(2/4) = 40 to 1

If you have two steel wheels of the same mass, the larger one will be more difficult to get rolling (there is a larger change in momentum).

So it is 5x easier to roll than pitch.  I think that should be accounted for in the PIDs?  But maybe I'm wrong.

Of course this is an extreme example where everything else weighs nothing, so the differences in ratios are never that high.  But it is common I think for the factors to be up to 1.5X.

Your thoughts?

At 1:42pm on November 8, 2013, Tyler McGahee said…

Yeah, the PIDs are definitely affected by the "mass distribution" (moment of inertia), as well as by the motors and propellers and ESCs and the control algorithm and on and on. I don't think it hurts to list the PIDs though. Could save some time when starting from scratch on a similar or identical rig.

Hello,

A curiosity ... as I turn apm 2.5 and esc with 2 separate batteries.

Battery 1: APM 2.5 and FPV
Battery 2 Engines - BECS (servos)

Unrecognized?

Thank you!

Ardupilot on PX4 + IO won't arm motors.

Hi I have the same problem Mystery 30A ESC's ...

You Might explain "load up the firmware ArduCopter" Bootload firmware?

System works without problem, arm and disarm perfectly.

Safety Switch OK.

Calibration OK, ENGINES TURN.

Connect and disconnect battery and ESC sounds uncalibrated, not save settings.

Hi,

/ / / / / / / Can not save the ESC Calibration in PX4 FMU IO / / / /

You know it could be?

Another question.

You know how I connect to OSD Remzibi px4 as if telemetry data and to see video on my monitor?

We appreciate evidence.

Thanks for you time.

You are responsible to give answers of diydrones community? curiosity!

4 motor mounts and 4 tube plugs, cut, lightly sanded, ready to ship, and after you clean, ready to adhere.

Where do you want me to send them?

Saw an old post from 2013 title Tiger motors-propellers combinations for an heavy lift octocopter, where after testing several motors props combinations you chose the Tiger 3510 360Kv.

I'm trying to upgrade my 3dr x8+ to be able to extent the flying time while increasing the payload to be able to use about 1200 extra grams for camera equipment etc.  At present my drone is equipped with the motors and props that come from 3DR ( SUNNYSKY V2216-16 KV800) and by them the drone will be able to lift 800 grm while having a fly time of 15 mnts (by what I have read more like 10).

I was wandering if you think that using the Tigers and the props combination I could achieve the results you had, also whether

I could run the 6s batteries.

Thanks so much for your time
