The Sharma range of model engine, kits and accessories has been manufactured in Jodhpur, India since 1974 by Sharma Model Aero Engines & Propellers, a family-owned and operated company. Sharma has produced both diesel and glow-plug models, although the company is best known for its range of diesel engines in 1.5 cc, 2.5 cc and 3.2 cc displacements which remain available today.
At first glance, these units appear to be very much influenced by the design of the PAW engines from Macclesfield, England. However, a closer examination reveals that they embody a number of features which distinguish them very clearly from the PAW designs. They are well-made and sturdy units having highly acceptable levels of performance by "classic" standards and representing excellent value for money. I've been using them myself since 1997 with complete satisfaction.
A complete history of the Sharma company, together with tests of a representative sample of their engines past and present, may be found elsewhere on this website.
