Yes. Safety above all else is top priority within our club and should be within any other club too.
Regarding just the model itself and it's power train, whether electric or internal combustion (glow or petrol). Keep objects, loose clothing and body parts away from the rotating propellor. Do not stay in front of it and including all spectators stay behind the model.
When connecting a main battery in electric models assume that the model is "live" and treat it as you would an ic powered model. On contact with objects, etc, motors do not stall and stop like an engine would.
All models must be restrained before starting or connecting a battery.
