I apologize!
Hi Jenish, it would be hard to create/build a heli at home. Helis are precise machines requiring precise components! It would be very difficult to assemble a heli even if we already have all the readymade parts to build.
Though it would be considerably easy to build something like a tricopter or a quadrator etc, but even that would not be easy for a beginner.
To give u an example of how precise a heli should be, the main baldes/wings of the heli should not have a diff of 0.10 grams and I would reduce that to 0.01 Grams. So if you buy a simple toy heli from a shop and put a motor into it, it wont fly!
In simple words you cant create a heli at home from scratch, you need to buy kits and assemble it. A minimum investment of 15,000 + is required.
Or you can buy a simple READY TO FLY HELI for approx 1000 rs.
