Learn how to install rail guides on your high-power rocket with step-by-step instructions. Get your rocket safely off the rail every time.
Quick answer
To install rail guides, mark the guide positions on your rocket body, drill pilot holes, and attach the guides with the supplied wood screws. Use a rail button set that matches your launch rail size.
Why rail guide size matters
Rail guides come in sizes that match specific launch rails. Using the wrong size can cause binding or poor alignment during flight. The Rail Buttons Series 1000 works with 1" rails, while the Series 1500 is designed for 1.5" rails. Choose the set that matches your launch pad.
Step-by-step installation
- Mark the guide positions: Place your rocket horizontally on a flat surface. Use a long straightedge to draw a line from nose to tail along the side of the airframe. Mark two points on that line: one near the nose cone shoulder and one near the motor mount. Space them evenly to distribute the load. Common mistake: marking guides off-center or too close together can cause the rocket to wobble on the rail.
- Drill pilot holes: Use a drill bit slightly smaller than the wood screw diameter. Drill straight into the airframe at each mark. For fiberglass or thick cardboard tubes, start with a smaller bit and step up. Do not oversize the hole or the screw will not grip. Checkpoint: hold the drill perpendicular to the tube to avoid angled screws.
- Attach the rail guides: Align the rail guide over the pilot hole. Insert the wood screw through the guide and into the hole. Tighten until the guide is snug against the airframe. Do not overtighten, as plastic guides can crack or strip the threads in soft tubing. Common mistake: overtightening can crack the guide or damage the airframe. Hand-tighten only.
- Test fit on the rail: Slide the rocket onto your launch rail. It should move freely with light friction. If it binds, check alignment. If it wobbles, the guides may be too far apart or the rail size mismatched. Checkpoint: the rocket should slide without forcing but not rattle side to side.
Product facts
