Quest Q-Jet™ F41-8W White Lightning 雙馬達完整發射包 - Q6162

These things punch way above their weight for the size. The 14.8% extra impulse over a standard D12 was obvious on the launch rod, and I love that they're noticeably lighter to carry around.

Took these Q-Jets out to the field and the 14.8% more impulse made a noticeable difference in altitude compared to my old D12s. The motors are noticeably lighter too, which made prepping the rocket feel quick and balanced. My first flight was a clean, straight boost that left a satisfying smoke trai

The lighter casing makes a real difference on the pad, and the extra impulse over a regular D12 is noticeable in the first few seconds of flight. Only ding is the igniter wire feels a bit delicate to handle, but it lit without fuss both times I flew it.
