Ritewing Mini Drak – The Mist

Ritewing Mini Drak is a very stable airplane, but when the air is bumpy, the flight will be bumpy as well. This is why I'm experimenting with a soft image stabilization.

For video editing, I'm using Magix Movie Studio 15 and it has a built-in video stabilization plugin. But it does not work: waste of time. So, I've got me something else: newBlueFX Stabilizer.

In this video, some of the takes are stabilized, some are not. You should not have much trouble finding which ones I've stabilized with newBlueFx Stabilizer and which not. I've tried to find the settings that are soft enough not to make it look super strange or something. Did I succeed? Not me to judge.

Ritewing Mini Drak – Above The Fog

Weather like this happens only a few times a year: raising fog, low sun and another layer of clouds… And very little wind. To be honest, when I went to the "airfield" I did not expect to use my Mini Drak at all. The fog was too dense and too low. But then it raised and holes appeared… Awesome…

ZOHD Nano Talon V-tail airplane review

Let's cut to the chase: my final review of ZOHD Nano Talon is: this airplane is crap. Just like that. Period. It might be good looking, it might be spacious inside and quite well thought through but it lacks one thing: it does not want to fly well. As simple as that.

As long as air is calm and there is no wind it's kind of OK. You can even have some fun with it. Yaw still sucks, a roll is strange but it's OK. But as soon as wind appears and Nano Talon has to fly through the disturbed air, it is over. This thing just does not wants to fly straight. Always tipped to one side, unresponsible and wobbly. Nope nope nope…

Crossbow LRS, range test that did not went well….

Yestarday I wanted to make a first "real" range test of my DIY LRS system. "Real", because RX was supposed to be on a flying wing, but only as an passenger. Actual control was supposed to be happening via FrSky X8R. Crossbow RX was only to measure RSSI and check for failsafes.

It, well, did not ended up very well. Just watch the video.

Project “Dropship glider” – failure #1

I’ve described my Dropship Glider Project here. Previous weekend I finally tested its ability to glide when dropped from a drone 50m above the ground. And well… to be honest, I failed hard this time. Just see this short video from FPV camera:

Dropship survived two drops. After second one, AIO camera/transmitter combo got damaged. Continue reading Project “Dropship glider” – failure #1

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.

Dropship glider - depron FPV delta 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 gravity right. And did not made ailerons too big. Or…

Dropship glider - depron FPV delta glider

Delta 6mm Depron "wing" is attached to 6mm carbon fiber rod and has some quite big dihedral: 15 degrees.

The biggest problem was radio link and mixer for ailerons. I could not use my Taranis: I need that for a carrier and only radio control link I had was EM-16 with PPM output only and no way to setup any kind of mixer. The radio just has no "features" like that…

So, took one Arduino Pro Mini and wrote short program that acts as PPM decoder and mixer for ailerons.

  • power is supplied by 1S LiPo taken from my Tiny Whoop
  • FPV AIO Eachine TX02 also taken from my Tine Whoop
  • 5V is supplied from cheap, regulated, step-up converter
  • 3rd servo is to release tether

First flight, or rather drop, tomorrow. There will be a video from the event of course…

Marabou Stork decommissioned

Depron airplanes are easy to build, but also do not last long. Few weeks ago I decommissioned by Marabou Stork. It did not crashed, it was flying almost fine, but it had at least a few problems:

  1. Motor was overheating. Just like that
  2. Wing that I originally designed for something weighting around 450g, now had to work with twice that much weight. Take offs were, at least, problematic
  3. It was big and slow and was not giving enough fun

So, to paraphrase Monty Python:

This is a late marabou stork

It's not a complete end of this design. Wing is still in pretty good condition and I have a plan to reuse it in experimental twin-motor design. But that later this year… In a mean time, last video footage.
