Apple Tree Innovation is a small specialist engineering consultancy company, based in Cheshire, England (United Kingdom) for specialist in designing and engineering projects, including high powered DC Battery Systems for Electric Motors in EV and other Hybrid applications and also lightweight aero diesel engines for use in light aircraft burning Jet A1.

WAM engines

Formed in early 2018, Apple Tree Innovation acquired all the assets, inventory, patents and intellectual property of Wilksch Airmotive Ltd., retaining key personnel to continue to supply ongoing spares and be the definitive source of product support. This will include working with a new partner in Cheshire to facilitate rebuilds of engines and other service activities as required.

In July 2019 all the activities at Gloucestershire Airport, Staverton have been relocated to Antrobus, near Northwich, Cheshire. Due to a lack of market penetration the WAM project has now ceased as of July 2024, however the website details remain available for historical support.Support material for the WAM series engines is available here.

Apple Tree Innovation is a trading name of Tiga Race Cars Ltd.
