Ultra light helicopter

[Okidi]

Dear all, 

Currently am trying to build ultra light helicopter for crops dusting but due to financial status, I want to use sport motor cycle engine, 180KPH,  engine weight is 55kgs. Please advise if this will work well or any one had the same experience.

Have you explored the use of two-stroke engines and multiple props?

If I were you I would start from buying 3D printer, if you don't have one, and making toy models of drones and helicopters, to gain knowledge and experience.

If you will master it, you will be building them bigger, bigger and bigger with time.
