Project Dualcopter – worklog #4
More than a year after staring this damn project, I finally decided what goes where. And on top of that, short description how Dualcopters works (or at least should work). There are two counter rotating propellers on top. They are responsible for thrust and YAW control When both props turns faster, dualcopter gains altitude When…

QuadMeUp Crossbow LRS: introduction
Few days ago I mentioned that I'm working on my own DIY long range radio system (LRS) that I named QuadMeUp Crossbow LRS. Today I will share some more details about it. First of all, I'm not creating anything new or "amazing". There are plenty of "DIY" or OpenSource LRS systems. OpenLRS for example. Or…

Project Dualcopter – worklog #3
It's been exactly one year since my last update on Project Dualcopter. On 20th of October 2016 I've posted that there was a progress. Now, 12 months later, I once gain report, that there was a progress…. That was slow…. I've finally installed control surfaces and servos I've finally decided where LiPo will go: to…

Wind your own motors? Will they burn or work?
Half a year after first tries (failed) to wind a DIY motor from Banggood (it’s not in offer any more BTW) I gave it another try. This time, with new tricks in my sleeve and new ESC. It ended up, well, watch the video…

Project "Dropship glider" – introduction
When I saw this video from rctestflight I knew I will build something like that for myself. A voila, few months later it is done. Here is Dropship Glider. It is 29cm long with 20cm wingspan. Weights 97g AUW and has 21g/dm^2 wing loading. So, in theory, should glide. Somehow… If I got center of…

How to read PPM signal with Arduino?
More than a year a published a post called Generate PPM signal with Arduino. Today it's time for part two: How to read PPM signal with Arduino?. Strange thing: internet does not gives very useful information on this topic. Strange, right? Some links to pages that does it either very very wrong or in not…

AnyFC F7 and DIY buzzer for INAV
Because both original and Banggood clone of AnyFC F7 flight controller and missing buzzer support, its usefulness is somehow limited. There is no dedicated pin and driver. Next release of INAV (1.7.2) will finally solve this problem by reusing Motor #9 output as buzzer output. But, some additional hardware will be required. To be precise,…

DIY brushless motor kit – I give up, for now…
Latest update on the topic of DIY motor kit from Banggood (DIY Assemble 2204 2-3S Brushless Motor 0.42*2.8 Copper Wire with Motor Cap Banana Plug): I give up. For now, at least. In total, I tried to wind this motor 6 times. In every single case it ended in the same way: one of the…

DIY brushless motor kit – first failure
Just like it was expected, my first attempt to wind a brushless motor (12N14P) was a failure. Probable cause: short circuit between phases and my creation released magic smoke. Then I tried for a second time, and failed again. This time less, no smoke, but motor overheats and does not want to start most of…
