The Estes C11-5 is a reliable mid-power engine ideal for customers transitioning from standard 18 mm motors. With a 24 mm diameter and 10.00 N-sec of total impulse, this engine offers a noticeable performance boost for mid-sized rockets requiring extra thrust and altitude potential.
Its consistent 5-second delay and solid 0.80-second thrust duration make the C11-5 a dependable upgrade option for hobbyists looking for more lift without committing to E-class engines. A strong seller for mid-level fliers seeking more advanced flights.
