Review for LEGO set 6345 Aerial Acrobats from Brickset
The complete airshow experience — “This four-part set is a real treat. Not only does it include two extremely well-made propeller aircraft, ones that fully justify buying this set on their own, it also features a unique van/trailer combo and a set of spectators. The aircraft are virtually flawless. The bulky... More engines and details such as the exhaust pipes on the biplanes really do make them look like high-power stunt aircraft.”
