Scottish pupils competing in the F1-in-Schools world championships are making their final preparations before jetting off to Malaysia next month.
The pupils, from Lochgelly High in Fife and Blairgowrie High in Perthshire, will be racing their model Formula One cars against teams from around the world in the capital, Kuala Lumpur.
The champions are Team Fuga, from Northern Ireland. At the world championships in Melbourne last year, their Formula One car - a 1:20 model, made from balsa wood and powered by CO2 - sped down the 20-metre track in 1.02 seconds, at a scale speed of over 220 miles per hour.
This year, the challenge will be to break the one-second barrier - and, for Blairgowrie, to go one better than the school's team last year when they were runners-up.
Lochgelly High team XLR8 believes the key lies in the wheels. Fusion from Blairgowrie is concentrating on making its car as aerodynamic as possible.
