I like to highlight some safety precaution when flying models. Feel free to add to the list of precaution. Hopefully, this can become Daddyhobby safety manual.
1. Heli blade tracking should be checked while hovering and not holding it in ones hand and throttle up. Why? The rotor blade tip speed of a Trex @ 2400 rpm is 308 km/hr Raptor 50 @ 1900 rpm is 487km/hr Don't think anyone wants to get the tip into their eye.
2. Do not stand in line of a spinning propeller. Many onlookers/modellers not aware that propeller can come apart.
3. A good flying site is away from buildings, people and expressway. ( I know hard to find).
4. Be prepared to sacrifice your model if there is a potential risk of damaging properties or hurting someone.
