"No one from the NCAA has come to see what I've done. We don't reward talent in this country," he lamented.
Abdullahi does admit that his first helicopter lacks "some basic facilities like devices for measuring atmospheric pressure, altitude, humidity and the like."
In a country with Nigeria's abysmal air safety record officials may be loath to gamble on one student's home-made helicopter.
But Abdullahi, undeterred, has started work on a new flying machine, which, he says, "will be a radical improvement on the first one in terms of sophistication and aesthetics."
Currently just a spindly metal frame in the back yard, the helicopter will be a two-seater and Abdullahi calculates it will be able to fly at an altitude of 15 feet for three hours at a stretch.
