Currently, there is no legal framework for the use of drones in Liberia.
If you come in with a small drone (smaller than a Phantom 4), then everything can go well. It can also happen that you have to pay an import fee or the copter is confiscated. Since there are no rules, it is essential to the interpretation of the staff.
Similarly, the private use of drones in Liberia. Due to the political and economic situation in the country after the Civil War, you should refrain from traveling to Liberia with a drone, because it can get you into trouble very quickly.
If you still can not do it then be extra careful on every flight. Security organs can be susceptible.
The experiences described here come from native drone pilots with whom I am in exchange.
