Compare the AeroTech L1520T-PS and L1150R-PS RMS-75/3840 reload kits on price, propellant type, and hardware needs to pick the right 75mm reload.
Quick answer
Choose the AeroTech L1520T-PS if you want the Blue Thunder propellant and don't mind paying more; choose the L1150R-PS if you prefer Redline and want to save about $26 at the catalog price. Both are RMS-75/3840 reload kits that require the same 75mm motor hardware and a forward seal disc.
The real difference is propellant, not hardware
Both kits are reloads for the AeroTech RMS-75/3840 system, so they share the same aluminum case, forward seal disc requirement, and assembly process. The choice comes down to propellant type: the L1520T-PS uses Blue Thunder, while the L1150R-PS uses Redline. The catalog does not supply thrust curves or burn duration, so you cannot compare flight profiles from the listings alone. Use the propellant name as your guide and check AeroTech's official data for exact performance.
Price and value
At the catalog prices shown, the L1150R-PS is listed at USD 211.24 and the L1520T-PS at USD 237.24, both compared against a USD 324.99 reference. That makes the Redline kit roughly $26 cheaper. If budget is the deciding factor and you have no strong propellant preference, the L1150R-PS is the lower-cost entry. The L1520T-PS costs more but may be worth it if Blue Thunder is the effect you want.
What you need either way
Neither kit is flyable on its own. You must have AeroTech RMS-75/3840 motor hardware, which is sold separately as a complete set or as individual parts. Both reloads also require a 75FSD forward seal disc during assembly. If you are new to the 75mm RMS system, budget for the hardware and seal disc before choosing between these two reloads.
Trade-offs at a glance
- Propellant effect: L1520T-PS is Blue Thunder; L1150R-PS is Redline. Pick the one whose visual and sound signature you prefer, since the catalog gives no thrust data.
- Cost: The L1150R-PS is about $26 cheaper at catalog price. If you are indifferent to propellant, save with the Redline kit.
- Hardware commonality: Both need RMS-75/3840 hardware and a 75FSD forward seal disc. Your hardware investment is identical either way.
