The Estes C5-3 engine is built for rockets that need a stronger, steadier push from an 18 mm engine. With 10.00 N-sec of total impulse, 20.40 Newtons of max thrust, and a 1.85 second thrust duration, it gives mid-weight and higher-drag rockets the confident boost they need off the launch pad.
A 3 second delay helps bring recovery deployment earlier in the flight, making the C5-3 a smart choice for rockets that do not need a long coast before parachute ejection. It is a great option for intermediate flyers who want more control, dependable performance, and classic Estes engine reliability.
