Quick Answer

Choose the AeroTech L2200G-PS if you want a green propellant with a longer burn and need the standard 75FSD forward seal disc. Choose the L1256WS-PS if you prefer a white-lightning propellant and are comfortable using the stainless steel 75FSDSS forward seal disc.

Propellant type and burn characteristics

The L2200G-PS uses AeroTech's Green propellant, which typically offers a different burn profile than White Lightning. Green propellant is known for its distinctive flame color and can provide a longer, sustained thrust, which is often favored for heavier rockets that need a steady push off the pad.

The L1256WS-PS uses White Lightning propellant, which is a classic AeroTech formulation. White Lightning generally delivers a more aggressive, high-thrust burn, making it a good match for rockets that can handle a snappier liftoff and higher initial acceleration.

Because the two reloads use different propellants, your choice affects not only the visual experience but also the thrust curve and how the motor behaves during the flight. Consider your rocket's weight and the type of flight you want to achieve.

Hardware compatibility and forward seal disc

Both reload kits require specific AeroTech RMS-75 hardware, but they are not interchangeable with each other. The L2200G-PS needs the RMS-75/5120 motor hardware, while the L1256WS-PS needs the RMS-75/3840 hardware. Make sure you have the correct hardware set before assembling the motor.

The forward seal disc also differs: the L2200G-PS uses a standard 75FSD, while the L1256WS-PS requires the stainless steel 75FSDSS. This is a critical difference—using the wrong forward seal disc can lead to assembly issues or unsafe operation.

If you already own one hardware set, that may influence your choice. If you're starting from scratch, the cost of the hardware is an additional consideration beyond the reload kit price.

Trade-Offs at a Glance

  • Propellant: L2200G-PS uses Green propellant; L1256WS-PS uses White Lightning. Green typically offers a longer burn, while White Lightning delivers a more aggressive thrust. Choose Green for a sustained push; choose White Lightning for a punchy liftoff.
  • Hardware requirement: L2200G-PS requires RMS-75/5120 hardware; L1256WS-PS requires RMS-75/3840 hardware. They are not interchangeable. Confirm which hardware set you own before buying the reload.
  • Forward seal disc: L2200G-PS needs the standard 75FSD; L1256WS-PS needs the stainless steel 75FSDSS. Using the wrong one can cause assembly or safety problems. Double-check your forward seal disc type during assembly.

Which Reload Fits You?

Best For

  • L2200G-PS: Flyers who want a longer burn for heavier rockets and already have RMS-75/5120 hardware.
  • L1256WS-PS: Flyers who prefer White Lightning's classic thrust and have RMS-75/3840 hardware.

Not For

  • L2200G-PS: Not for those without the RMS-75/5120 hardware or who prefer a short, aggressive burn.
  • L1256WS-PS: Not for those who need a longer burn or only have RMS-75/5120 hardware.
