Park-cruiser, pylon-bruiser, or full-send speed machine — same airframe, three EDF sizes, two looks. The F-87 kit lets you choose your timeline: build the Astral Thunder, a sleek interceptor from a golden age of aviation, or the Cosmic Predator, a 'Mad Max' style racer from a gritty future. Both cosmetic variants are included, allowing you to pick your power level and flip between the clean lines of a retro-future jet or the aggressive look of a reno racer.
Key Features
- Alternate History Lore - Pilot the interceptor from a timeline that never was
- Dual Cosmetic Variants - swap between Astral Thunder and Cosmic Predator looks
- Filament Alignment - Uses filament segments for precise alignment of fuselage sections during assembly
- Three Sizes - Choose between 30mm,40mm, and 50mm EDF
- Zephyr Manual Viewer – The ultimate build companion for Mac and Windows. Ditch static PDFs for fully interactive 3D guides. Rotate models, identify parts instantly, and follow clear step-by-step assembly instructions to build your aircraft with confidence
