Spotlight Review

"Never Failed"
Not to sound like an Estes fan boy, but I have probably launched a hundred of these motors during my life time and probably seen 3 times that number by others. I can honestly say that I have seen a failure to ignite or problem during thrust, ejection etc. probably only 2-3 times that can be attributed to the motor alone. (Igniter failure, short etc. excluded). Given that most of these launches were for young kids, myself included at one time, this is probably a good thing. I would dread the day my 6 year old daughter's rocket that she colored by hand goes up in smoke the wrong way.

"Great engines"
Ho moduler
The name if these engines really describe it all: they are STANDARD engines. Be careful with them because they can be dangerous.

"The old standby"
zjracing (Oregon)
These engines are totally dependable. Never had a bad one yet. For a 18 tall rocket with a 1.3 diameter this engine will get it off the ground ok with a quick recovery ejection. Great for small launch areas or windy conditions. For small rockets with streamers this ening will really get it way up there but not so far you'll lose it. I always use these great engines every trip out.
