I do not have the skills or expertise (or money) to make a real functional prototype of my product so would it help if I made a model of it demonstrating the features? Would it make is easier to raise VC money? The product is a compact recreational hovering vehicle that uses two small turbojets to achieve lift. In addition to selling this product to the public, we plan to make a spectator sport out of it, think of it like NASCAR but with hover vehicles.
Yes, in order to explain your idea a model will be helpful, which you can also take photos of to support your description online.
Consider using drone parts to build a cheap small scale functioning prototype.
Drawings can help, whether engineering or illustrations (what ever is cheaper to start) and support your description online.
Understand the trade off involved for VC money - how much equity and control you are willing to lose in exchange for this.
Figure out how much money would be required, even if only estimating the parts list at first, and what you need to be selling to determine if it's a potentially profitable venture before spending time on it.
How much are cargo drones costing? What can you learn from these?
How can you validate whether you've identified a buying market for this?
