Review Summary

The reviews highlight the product's strong performance as a reloadable mid-power motor, praising its cost-effectiveness, durability with multiple uses, and impressive visual and auditory effects like bright white flames, thick smoke, and a deep roar. Users appreciate the thrust curve for providing a hard initial hit followed by sustained thrust, though some note occasional ignition difficulties with the White Lightning propellant. It's widely recommended for mid-power rocketry enthusiasts, with successful flights reaching significant altitudes and aiding in learning advanced techniques.

Greatest bang for the buck motor!

By: reytech

Has to be one of the best 'bang for the bucks' reloadable 29 mm motors, in my opinion! The White Lightning propellant produces a big, bright white flame and lots of smoke! And a nice very audible sound as soon as it ignites! One of my favorites.

Excellent Economy Reusable Engine

By: Hulksmasher123

This is actually pretty good for its price. It's refillable so technically it can be used forever or until it breaks. So far I've refilled this 7 times and used it 7 times. It doesn't look to be breaking any time soon.

Hits hard, plus a good sustaining thrust

By: Larry

I've used G64's for approximately 25 years, and it's a great motor. The thrust curve of the G64 is nearly perfect in my opinion. It hits hard and can have a 2-pound rocket moving at very stable speeds (45 ft/sec) at the end of a 5 or 6 foot launch rod. After the initial punch, the thrust tapers off due to the C-slot grain design, providing a nice, long sustaining thrust. The only downside I've encountered with White Lightning propellant is that it can be difficult to ignite at times. A thermalite booster can be helpful in this case.
