Shrediquette - the award-winning multirotors by William Thielicke

Today I finished the last test under veeery windy conditions, and everything went fine. The files at the right hand side (GUI and firmware) are updated. Please note that the new firmware will only work with the new GUI and vice versa! You will also not be able to use your old settings files. Double-check the direction of your servo, something has changed here too. The firmware should allow to increase control loop parameters, especially Acro-P and Hover-D. That should make your tricopter more stable. A new default-settings file is included, as well as my settings for the DLX and the DLXm. You can flash the firmware using my GUI. The file Tricopter_m328p_11.hex has to be placed into the GUI folder.

The Shrediquette DLX standard size tricopter and the Shrediquette DLXm micro version, both got a small webpage with new detailed pictures and specifications: Micro version: --> Shrediquette DLXm <-- Standard version: --> Shrediquette DLX <-- If you still miss some details/ pictures, let me know. I also modified the FAQ section , please have a look at it too.

The Shrediquette DLXm micro-tricopter flies better than I ever expected. New control loops make it very stable in fast flights, during aerobatics, when there is wind or when it is flying in it's own downwash/ the ground effect. Watch the DLMx presentation in HD: Shrediquette DLXm - Self Stabilizing & Aerobatic Micro-Tricopter. The Movie. Thanks to Stefan for milling the frame (in carbon fiber, hehe) and to Eric for borrowing the ESCs!

As a result, the gain of the gyroscopes c...

Here are some pictures of my Shrediquette DLXm. Unfortunately I am still waiting for the ESCs... Slightly annoying. EDIT:The ESCs arrived (thanks to Eric!) and first flights were very successfully completed. The control loop had to be modified to account for higher demands of this micro tricopter during aerobatics and fast flights. Because larger Shrediquettes will also benefit from this modification, I will soon release a new firmware and a modified GUI. I will now start to collect some video footage and make a new movie.

Ok, I am actually still waiting for my ESC order to arrive (for the Shrediquette DLXm)... I was hoping that the ESCs would arrive during my holidays last week, but they didn't. So I am not able to present you a nice video of the Shrediquette DLXm in flight, shot with my brand new GoPro HD Hero camera. But you might nevertheless be interested in seeing some footage that was shot with my cam during last week's holidays. I am absolutely impressed by the exposure control of the cam and the high resolution/ slow motion feature. This seems to be THE cam for on-board videos...! Video: http://www.vimeo.com/10375186

Here is a movie showing how to use the GUI: TriGUI_tut.wmv

The design for the new mini Shrediquette seems to be finished by now. Here are some images:         Specs/ design goals Motor shaft distance: 139mm  Max. dimension: 266mm Weight: 261g Props: 5x3 3-blade GWS Motors: Roxxy 2216-25 Battery: 3S, 800mAh Thrust per motor (measured): 237g Thrust to weight ratio: 2.7:1 Current during hover: 4 A Endurance: 11 mins Hopefully I'll soon find some time to put it together...!
