We have a diverse manufacturing program plus Integrity appreciated worldwide. At present we produce 8 models with 16 variants, producing from 3.2HP to 45HP, with battery and magneto ignition systems. All but one feature Reed Valve inlet systems resulting in High Torque Midrange power capable of turning large diameter props with superior throttle response. Ideal for aerobatics competition. On the maximum power front, Quadra_-Arrow engines have powered over 100 winners since 1991. These include several Grand National and World Champions at Madera, Rio Vista and Rialto California, Phoenix and Tucson Arizona, Reno Nevada and Galveston and Gainesville, Texas. iMAC competitors appreciate the smooth, utterly reliable & trouble free performance.

Perhaps the most remarkable feat is the 3 year unbroken winning streak of the Q75RSS (gasoline) in the Biplane class of (#88) Kent McKenna's Mong.
