Another interesting concept of "scale flight" is "time". If you could scale time the same way you scale a model it would be possible to achieve perfect scale flight appearance....both with the proper speed in level flight and with the proper bank angle and turn radius.

A way to scale time is to film the model in flight and then show the video in slow motion. Take the example above of the heavy Hurricane model flying fast but with the correct turn radius. Showing that same flight in slow motion the bank angles and turns will look correct and the overall speed will also look correct. This is in fact how movie makers often film models to provide a true visual allusion...ie. The Battle of Britain: "The other need was for models in aerial sequences, and art director and model maker John Siddall was asked by the producer to create and head a team specifically for this because of his contacts in the modelling community. [SUP][Note 4][/SUP] A test flight was arranged at Lasham Airfield in the UK and a model was flown down the runway close behind a large American estate car with a cameraman in the rear.[SUP][citation needed][/SUP] This test proved successful, leading to many radio-controlled models being constructed in the band rehearsal room at Pinewood Studios. Over a period of two years, a total of 82 Spitfires, Hurricanes, Messerschmitts and He 111s were built.[SUP][19][/SUP] Radio-controlled Heinkel He 111 models were flown to depict bombers being destroyed over the English Channel.
