Happy New Year the inhabitants of our site!
Once, a very long time ago, I did this kind of "exotic" model
The author of the proposed Christmas tree model apparently saw something similar and decided to experiment.
The author of this flying Christmas tree is not alone in his endeavors.
Here is a small video of another flying Christmas tree.
Here is what he suggested.
His drawings on notebook sheets with great difficulty can be called drawings.
The shape of the Christmas tree paws and their dimensions, I think, are not critical.
The author made the model multilayer, but it is better to make it from two layers of ceiling tiles (ceilings), 4 mm thick.
In this case, there is no need to choose an extra ceiling to facilitate, as the author did. The model will be light enough anyway, and there will be much less work.
So the author suggests making elevons.
When performing a model of two layers of the ceiling, working with elevons will also be significantly less.
So the author suggests making an engine mount.
During installation, a thermal gun is used.
Marking the installation of servos.
Servos, boars are installed, traction is connected.
The motor is installed.
Well. and you can decorate the tree to your taste. Not necessarily as its author adorned.
In conclusion, I want to add that the most important thing in this model is to accurately determine the CT (center of gravity).
Characteristic of the model.
Length - 1000 mm.
Span - 800 mm.
Motor - D2830-11 1000kv
Regulator - 25A
Battery - 1350mAh 3S
Weight - 200 g.
Based on the model created by the author, there is a huge field for experimentation.
I wish you success in creating "flying" Christmas trees!
