Design and development
The Blackburne Tomtit engine was developed from Blackburne's motor-cycle engines. The first one adapted to aircraft use was the best performing engine at the Lympne light aircraft trials of 1923, despite the lack of refinement. The Tomtit was a modified version of the Lympne 696 cc V-twin, marketed specifically for flight.
The Tomtit could run upright or inverted and was the first British engine to fly inverted, in the ANEC I. The inverted configuration was more common, but the Avro 558 used it in the upright arrangement, and the Avro 560 flew with both upright and inverted Tomtits.
