Frequently Asked Questions
What rocket models can these A3-4T engines power?
These 1/2 A3-4T engines are designed for lightweight model rockets. With a maximum lift weight of 1.0 oz (28g), they're suited for mini/small model rockets. Check your rocket's weight to confirm it falls within this limit.
What's included in the 4-pack?
Each package includes 4 A3-4T engines, 4 starters, and 4 starter plugs—everything you need for 4 flights.
How long is the delay before the parachute deploys?
The 4-second time delay gives your rocket time to coast upward before the ejection charge fires to deploy the parachute.
What are the engine dimensions and weight?
Each engine is 1.8 inches long with a 0.50-inch diameter and weighs about 0.23 oz (6.5g), making them very compact for mini rockets.
How high can these engines launch a rocket?
The A3-4T produces a maximum thrust of 8.30 Newtons with a brief 0.30-second burn and 1.25 N-sec total impulse. Actual altitude depends on your rocket's design and weight, but these are engineered for small, lightweight flights.
