Learn to install and use the AeroTech 54mm Delay Drilling Tool to adjust RMS delay elements for precise ejection charge timing.
Quick Answer
To install the AeroTech 54mm Delay Drilling Tool, first ensure the drill bit is flush with the tool body, then use it to shorten the delay element to your desired delay time before assembling your reload kit.
Why Adjusting Delay Matters
Getting the ejection charge to fire at the right moment is critical for a safe and successful flight. The delay element controls when the ejection charge deploys the parachute. If it's too long, the rocket may still be moving fast when the chute opens; too short, and the chute opens too early, wasting altitude.
The AeroTech 54mm Delay Drilling Tool lets you shorten the delay element in precise increments, giving you control over your flight profile. This is especially useful when you're flying with a different motor or in varying conditions.
Step-by-Step Installation and Use
- Calibrate the Tool: Before first use, ensure the tip of the drill bit is flush with the tool body. Use the calibration provision to adjust if necessary. A common mistake is skipping this step, which can lead to inaccurate delay adjustments. Always verify calibration before each session.
- Prepare the Delay Element: Remove the delay element from your AeroTech 54mm RMS reload kit. Inspect it for any damage. Do not attempt to drill a delay element that is cracked or deformed. Check the delay element for integrity before drilling.
- Insert the Delay Element: Place the delay element into the tool body, ensuring it sits firmly. The tool is designed to hold the element securely while you drill. A common mistake is not seating the element fully, which can cause uneven drilling. Make sure the element is fully seated before drilling.
- Drill to Desired Delay: Rotate the knob to drill into the delay element. The amount you drill determines the new delay time. Refer to your motor's instructions for the correct depth-to-delay relationship. A common mistake is drilling too fast, which can cause the bit to bind. Drill slowly and steadily for a clean cut.
- Verify and Assemble: After drilling, remove the delay element and check that the drilled hole is clean and free of debris. Then proceed with your normal reload kit assembly. A common mistake is forgetting to clean out the drilled hole, which can affect the ejection charge burn. Clean the delay element before assembly.
