performance and value-for-money are all combined to provide electric
motors that cover the smallest indoor models right up to sizes that are
usually the domain of 50cc petrol engines. There are specialist
helicopter motors, those suited to gearboxes and EDF and motors that
offer a direct replacement power output for all the popular glow engine
sizes. The Quantum 4120/05 for instance would be an ideal choice for a
standard trainer like the Irvine Tutor 40. The price and specification are right, so the choice is yours!
