Model Motors produced two motors for competition-level F3A pilots. The AXi 5330/F3A is designed for F3A models up to 5,500g (194oz) and is usually suitable for practice flying with older/heavier airframes which may be above the 5,000g weight-limit. The slightly shorter and lighter 5325/24 offers the optimum solution for models up to 5,000g (176oz) such as the Wind S Pro and Krill Spark.
Both motors are designed for best performance with 20"x13" propellers such as the APC-E Thin Electric or the AXi 20x13 Carbon F3A Propeller. Expect to draw in the region of 85A at full throttle on either setup.
