Spotlight Review

"This is one big rocket!"
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.

"BIG Rocket at a Great Price!"
FinBurner (Brandonbacn@outlook.com)
This rocket is BIG! The parts are high-quality and the Aerotech Fin-Lok mechanism makes it really easy to get the fins straight. I'm not so sure about the cooling mesh as I've heard reports it can become clogged, but I haven't experienced that yet. The nose cone required some work (it is heavy duty but the cast lines were obvious). Launching this on a G80 is impressive and LOUD. I highly recommend this for those of you wanting to get a BIG rocket - and the price can't be beat!

"Excellent rocket"
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.

"Overall an incredible bird with very few problems discovered."
jwjohnwaller0406 (Rosalia, Kansas)
You know what you just bought as soon as you cut that tape and open up the box! The sheer quality of Aerotech kits amazes me. This rocket in particular though is a very straightforward build. The instructions and diagrams included with this kit make it extremely difficult to make mistakes. And since it is a bigger bird, just keep in mind before you start building it that you will use epoxy on the integrated support structure parts please!!!! The last thing you want is for you to be responsible for someone getting hurt at your launch because a fin or the motor tube assembly wasn't equipped to handle the higher stresses of F and G powered flight. I only had to deal with a few minor problems when completing this kit. When the fins came out of the mold, the fin roots of every fin had an arch to them. With some fancy work with a #11 bladed hobby knife and some sandpaper, the issue was resolved. You want the fin root to be flat against the body tube so that the Fin-Lok's snap all the way into place and it makes an even contact with the surface of the body tube. Since the fin roots aren't contoured to the shape of the body tube, some simple filler or putty is needed to fill the gap underneath the fins. These are all minor and should in no way discourage you from buying this kit especially from Hobbylinc.com because you will not find a better price! Finishing this kit is a breeze provided you use a primer for plastics. You will need 320 grit sandpaper for in-between coats and it's always a good idea to put on at a minimum of two to three coats just in case the actual paint you bought doesn't specifically say it can be used on high impact polystyrene plastic. I made that mistake and the plastic WILL reject the paint and my paint said that it was for plastic!! Because this rocket is so big, the color options and schemes are only limited by the builders ability. Overall, you can't go wrong with this kit being in your arsenal. Have fun and stay SAFE!!!
