He used to fly paper aeroplanes during recess in school. His teacher, seeing this, realised the boy had a passion for flight.
So Navaneethak Kannan Srinivas, 10, was asked by science teacher Low Heng Chong to be part of a competition team designing and flying an aircraft.
Srinivas, together with his Jurong Primary schoolmates Foo Wei En, Haseenah Tahar and Wang Yu Xin, all 11, formed Team Hoverstar V.
Mr Low, who has taught in the school for four years, entered the Singapore Amazing Flying Machine Competition (SAFMC) himself in 2009.
He said: "I hope to inspire them to take part in future competitions when they are older."
The team in the Open Category immediately made history.
They are the first team from a primary school to take part in the category meant for unconventional aircraft. Participants are usually from polytechnics and universities.
Other categories like the Paper Plane and Unpowered Glider have younger representatives.
The competition has been held annually since 2009 and is jointly organised by DSO National Laboratories and Science Centre Singapore.
To take part, the young pupils had to manage their time, juggling studies and training sessions.
To allay their parents' worries that their studies might suffer, the team used recess time to prepare for the competition.
At the Singapore Polytechnic on Thursday morning, the pupils were the youngest amid a crowd of youths and adults.
