Spotlight Review

"Great second stage engine"
SteveAwesome (Highlands Ranch, Colorado)
I prefer this engine for my small to mid size 2 stage rockets as i am not into pure altitude - i like to see the apogee deployment of the chute. I highly recommend these for spectator launches, everyone hets to see all the action.

Great for lightweight rockets (2 ounces). Send your rockets high with enough of an ejection delay to bring them closer to the ground for easier recovery.

"First time using this engine."
zjracing (Oregon)
I was concerned about losing some of my rockets due to field size, wind, and parachute drift. I bought and used some to experiment. The recovery ejection delay is consistent and noticeably longer. The delay is so long some of my heavier rockets seriously plummeted to earth before the parachute popped, thought they were gonners. I actually had one parachute rip due to the speed it was coming down at when the parachute came out. I recommend these for small rockets that you really want to shoot high but do not want drifting a mile away, like those that use streamer recovery.
