Safety Information
⚠ WARNING: NOT A TOY. For builders and pilots 14 and older; under 18 only with adult supervision.
Radio-controlled aircraft can cause serious injury, death, fire and property damage. Read this notice before you start, and keep it with the aircraft. If you have a build guide or assembly instructions for your aircraft, follow them too. If you sell or give the aircraft away, include this notice.
Spinning propellers and fans can cause serious cuts, including loss of fingers, and eye injuries. Keep hands, face, hair and loose clothing clear any time a battery is connected. Disconnect the battery before working on the aircraft.
Lithium batteries (LiPo, LiHV, Li-ion and similar) can catch fire or explode if overcharged, damaged, punctured or short-circuited. Always follow the battery and charger manufacturers' instructions and warnings, including those for charging, use, storage, transport and disposal. Use a charger made for your battery type, never charge unattended, charge and store on a fire-resistant surface, and never use a swollen or damaged battery.
Batteries, chargers, motors, ESCs, servos, receivers, transmitters and other electronics are not made or supplied by The Ravens Forge. Always follow each manufacturer's instructions, wiring diagrams, ratings and safety warnings.
Loss of control, signal or power can send the aircraft into people, animals, vehicles or buildings. Fly only where it is safe and legal, away from people. Follow the AMA Safety Code and FAA rules, and do a range check and control check before every flight.
3D-printed parts can crack, separate or fail in flight, especially after a crash or a hard landing. Inspect the airframe before every flight and do not fly damaged or weakened parts. Inspection will not reveal all damage, including heat damage (see below).
Heat can soften and permanently warp printed parts. Our kits are printed in PLA, carbon-fiber PLA (CF-PLA), lightweight PLA (LW-PLA / Aero), or a hybrid of these and other filaments. Whatever the material, treat a part temperature of about 40°C (104°F) or higher as a risk. That is a cautious guideline, not an exact limit: parts can deform at lower temperatures depending on their shape, load, print orientation and how long they are exposed. A parked car can pass 60°C (140°F) even when it is much cooler outside, and dark-colored parts heat up faster in the sun. Heat damage is not always visible, but it can weaken the airframe and make it unsafe to fly.
Never leave the aircraft in a parked vehicle in warm weather, in direct sun, or near a heat source.
Do not rest heavy objects on the wings or fuselage, especially when it is warm.
If the aircraft has been exposed to heat (left in a parked vehicle, in direct sun or near a heat source), replace any parts that may have been affected before you fly. Heat damage is not always visible, so do not rely on a visual check to decide a part is safe.
Store the aircraft indoors in a cool, shaded place.
Changes to the design, materials, power system or setup can make the aircraft unsafe. Use components within the ratings published by the aircraft's designer, Eclipson.
Glues and sanding: use CA glue and epoxy with ventilation and eye protection. Sanding carbon-fiber-filled parts makes fine dust; wear a dust mask.
Small parts: keep away from young children.
