Sophia ★★★★★

The 4-inch airframe gives plenty of room for the three 38mm mounts, and glassing the tube was way easier than I expected. Flew it on three H motors last weekend and it went perfectly straight. Already planning a bigger cluster for the next launch.

Riley C. ★★★★★

Finally, a rocket that doesn't feel flimsy on the pad—the 4-inch airframe is rock solid, and the 3x38mm motor mount gives me plenty of room to try different cluster configurations. Put it together over two evenings, and the retro styling really stands out next to my other birds.

Riley ★★★★★

The 3x38mm mount cluster is a blast from the past and went together cleaner than I expected. I'm already planning my next launch day around this retro kit.
