Q-3 EnginesJett BSE .30 - see Jett Engineering
Q-2 EnginesJett BSE .25 - see Jett Engineering
MufflersMost of the engines for this class use the same muffler bolt pattern that the OS 32 SX uses. Check your engine before ordering an aftermarket muffler. Jett-Stream Mufflers - see Jett Engineering Ultrathrust Mufflers - see Performance Specialties Macs Products One-Piece Muffler
Engine MountsHayes AL-25 Long Mount 1.19 21-25 - This Q-2 and Q-3 compatible engine mount has the same firewall bolt pattern as the Jett Engineering 4 bolt conforming Q-500 backplate mounts and the Nelson Q-500 backplate mount. This makes it possible to set up a Quickie airframe for multiple classes. Weight shifting will be required since the Q-2 and Q-3 engines are significantly lighter than the 428, 424, and APRA engines.
