Use of Electric Models

1. For electric powered models, the electric power circuit(s) must not be physically connected, before the competitor is instructed to start his 8- minutes flight time and must be physically disconnected right after landing.

 

This means simply that electric motors should not be connected to power until they are in the ready box and asked to do so by the line director.

2. The propulsion system(s) must automatically shut-off or fully idle at the moment a R/C signal failure should occur. (closed throttle in failsafe)

And, this means that all fliers using electric models must have their failsafe programmed to cut the throttle to zero (including idle) if there is a break in transmission or severe interference.
All electric models flown at APA sanctioned events must have an external means of connection and disconnection of power.
