Snow racer

I was very interested modelproposed by the author.
This is a very simple and quite safe toy for children over 10 years old, and any adult with great pleasure will spend several hours in the fresh air, arranging snow races on this unit. For the manufacture of this model does not require large material costs, of course, in the presence of equipment for control.

The lack of a drawing, of course, complicates the situation, but looking at the photographs of the author and turning on your imagination, you can easily repeat the model you made.

First you need to buy three bottles of mineral water, picking up the bottles of the desired shape.
This is how the future model should look.

All materials proposed by the author can be replaced with aluminum sheet, 1.5 mm thick. or hardboard, And the slats can be replaced with the usual window glazing.

The adhesive that the author offers is not always sold and I propose the use of universal adhesive Titanium, CIN or Master.


We procure such small sticks.

We make cuts.


The distance between the cuts is 145 mm. Thickness - 8 mm. Width - 25 mm.

The width of the structure is 700mm.


Fitting parts in place and final dimensional check.




The supports are mounted at a distance that depends on the size of the bottles.






A prop is made for the front bottle. All supports are made to the size of those bottles that you buy. And the size of the blanks will depend on the diameter of the bottles.

A pilot cabin and a battery will be installed here.





You can make the whole model collapsible.





The connection of all parts is carried out by ordinary fishing gum.















Security arcs are inserted into them.
It is long 165 mm. 20mm wide.


Driven traction vector.
You can use any carbon rod or tube, a whip from a fishing rod.
Dimensions: 110 X 18 X 1.5 mm.

For guide tubes taken 1.5 liter beer bottles

The design is quite simple. You can fasten it with racks and a stapler, or you can glue it.





Heat shrink from steering backlash



You can use another cab mount.




This is the dashboard that the author offers. Show your imagination!

Put your pilot. The author has it like that.

So that snow does not blind, put a windshield.

From a wire with a diameter of 4 mm. arcs are made, tightened with heat shrink and fixed with screws or screws.




Weight may vary depending on the selected motor, battery, regulator, servo and materials.
I suggest this electronics.
Motor - C2836 / 08 1120Kv or similar.
Servo - any available.
Regulator - preferably 40A
Battery - 3S 2200


In conclusion, we can say - the main thing is that the model is solid. Build, experiment, you will succeed!
That's all, now arrange races on fresh snow!

If the bottles constantly flew out, it means they were poorly fixed. Personally, in the places where the brackets were attached to the bottles, I poured the universal, moisture-resistant Titan glue. And the fact that your model could only move on hard crust or ice was due to a lack of traction on the motor. It was necessary to put a more powerful motor and experiment with the size of the screw. I set the motor 3010 1300Kv with a thrust of 1650 and the screw set a three-blade 8 x6.
In our school, we already made a similar model, it has several drawbacks, the first of them is durability, the bottles constantly flew out, I had to put emphasis on the back of the bottles, the second is that they go only on infusion or ice. Although the model is quite interesting
