"Impressive"
hojomo88 (Eaton, Co)
The Aerotech G-Force is a very impressive rocket and very easy to build I used expoxy to attache the fins because of the stress of being heavy. I flew it for the fist time on a G38-7fj it was a slow flight to about 1,000 ft, awesome flight. The second flight was a Aerotech G80-7g green flame it was fast and hit about 2,000 ft. I flew it a local club lunch and there were several G-Force's they flew great, this has become one my favorites in my fleet.

"Excellent rocket"
dwgallivan
Aerotech rockets are a great way to make the jump to mid and high power. if you've been building Estes kits and are looking for something bigger, this is a great place to look. All Aerotech kits come with some awesome features that make construction easy (even easier than some Estes skill level II kits). The through the wall fin mounting (and the mechanism for connecting the fins to the engine mount) make construction a breeze. This particular kit is huge. Everyone will turn to watch it fly. It's fun to buold and more fun to fly.

"Can't get chute to deploy"
jgoode
Bealutiful rocket, easy to assembly kit; but I've had it with this model. Bought and built two of them, and watched both streamline into the ground without ejecting the chute. The first one was definitely my fault. I didn't use epoxy on the bulkhead firmly at the joining section. I surmise when the ejection charge popped, this diaphragm blew forward and the rocket volume just absorbed the charge... no deploy. Bought another (didn't paint right away) and made sure to epoxy ALL bulkheads tightly. Same thing happened. All bulkheads in place even after darting the dirt. I don't discount that I may have done something wrong, but all my other rockets perform flawlessly, or at least, I know when I've made a mistake. This last flight was a head scratcher... and expensive to boot. 2 rockets and 2 G motors gone. Great stable flight, majestic take off... I just can't get the chute to deploy!

"This is one big rocket!"
davidhoward
Assembly is straight forward on the G Force. I really like the fin-loc system. One thing to do is to pre-fit the fins before applying glue as per the directions. Make sure the rocket separates easily since this rocket pushes the edge of what the stock Aerotech ejection charge can handle. Mine will separate just from the weight of the bottom when you lift it by the nose and had no problems deploying the parachute. I used both CA for initial gluing and then epoxy to reinforce bulkheads and the fins from inside the tube. All the parts are quality made and the assembled rocket looks nice. On launch day folks really took notice! This rocket is big - it lifts off slow - and the G engines are loud as it gains momentum just like a real rocket. One stranger who was watching commented that it looked just like a NASA launch! Now for some cautions - the stock Aerotech launcher (Mantis)was challenged by this rocket. My advice - weigh down the launch pad legs with heavy objects (I'm trying pea gravel in ziplock freezer bags next time), don't shoot it any direction but straight up, and if you can find a stiffer and longer launch rod than the stock item you'll have better control over where this bad boy goes. I've watched cell phone video of our first launch and it looked like Elton John meets eight seconds. The launch pad was bucking and whipping around and the rocket man almost bit the dust! Overall a great looking and impressive rocket.
