"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.

"$66 are you kidding?"
jayorr (Utah)
What a great rocket! I have flown hundreds of mid & high powered rockets, and this one is too cool. Lets face it, these are simple rockets, easy to assemble. Nothing hard here. When you are done you have a very impressive looking bird. Low performance due to high mass, but this rocket could easily be flown on H power. For killer G flights, get a Mustang. I love mine! I read most reviews of this rocket. FOR HEAVENS SAKE, USE EPOXY ON THESE ROCKETS, And don't skimp on the epoxy. I also built mine with the body tubes EPOXIED together. The nose cone slips into the airframe easier than the coupler, just something I like better.

 
"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.

 
"Nice-n-Easy"

I purchased this rocket from Hobbylinc at a wonderful price of $66.59 and was the lowest price by far I could find. This is my first build on a mid-power rocket and I have to say it was very simple with easy to follow instructions. I took the suggestion from one of the other commenters and used epoxy (15 min) and didn't skimp on it either. I would have no problem or concerns with loading this bird with an H power engine. I encountered no problems during the building of this impressive rocket, all the parts were manufactured to compliment the other. I would suggest this rocket to anyone no matter what their skill level is. Like I said, this was my first large rocket and I had no problems following the directions and fabrication was simple. Thanks Hobbylinc!
