Kaifect,
Interesting idea. As long as the proper precautions and legal requirements (business licenses, insurance, etc).
Personally, I would never do this as it opens myself up to way too much liability and the headache of people messing with my stuff.
There would be some logistics -
- Do they get a copy of the video / images they take? If so, do you provide the USB? If not, how are they getting them - email/dropbox? Those are additional expenses.
- How many batteries do you have? How will you charge them? Will the fair let you hook into their electrical or will you need a generator?
- 15min is a long time for free flying in beginner mode ; customers may get bored quickly which leads to them doing 'dumb' things
- What is your 'WOW' factor? While flying the drone is cool, the fun part is what you get to see from the drone. The open area should have a building/shed/landscape to focus on
If you're not selling the physical drones - talk to some retailers and ask them if you can do a referral program with them. Once your customers are done flying you can say you offer your services or you can purchase your own drone from [vendor] using the offer code [x]. If the person buys from your referral you get $.
