Anti Jello mount for Mobius brushless gimbal

Posted on June 25, 2016 at 11:32am 16 Comments

To suppress vibrations & jello in videos taken by very lighweight camera brushless gimbals is a challenge as none of the classical methods are working well. The more weight, the easier it is to manage vibrations. When you combine extreme lightweight gimbal with a CMOS sensor technology, you'll get very prone to the so called "jello"…

Review & test of Gearbest's Pixhawk and comparison with 3DR's Pixhawk

Posted on May 16, 2016 at 8:27am 32 Comments

Recent 3DR's move not to sell DIY components & parts anymore, pushes hobbyists and prosumers to diversify their supplier's sources.  Like many others in the community, my issue is to find an "as good quality as 3DR" alternative for a Pixhawk board.  I started looking around for possible 3DR Pixhawk replacement candidates, with a quality I can…

Sub One Kilo project

Posted on April 26, 2016 at 11:36am 15 Comments

Hi,

In Belgium, our local "FAA", the so called "DGTA" (as painful as in the US) has just passed last week a law regulating the use of drones. They defined a number of categories among which the "all-up-weight" of the ship is a criterion. Among the categories, a ship under a kilogram does not require a pilot certification nor all of the…

Easter chickens could care less about Hobbyking's carbon fiber tubes...

Posted on March 26, 2016 at 1:13am 22 Comments

 

Hi, I bought these very cheap hobbyking rectangular carbon tubes. I made this not so serious experiment with them as they could potentially be great to build your own multicopter frames. Tridge, by the way, used those recently in his quadplane build he posted about on diydrones.

And, this is a not so serious contribution to coming Easter…

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!

Thanks.

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
