Rocket PicBrief:
Aerotech's 4", matey, G-powered, ya bilge rat, parachute recovered rocket usin' their proprietary LABYRINTH ejection baffle system.

Construction:
Pros: Big (for Aerotech) Easy t' build, very nice flyer
Cons: Limited recommended motor range. Very thin fins. Blimey! Pricy.

Bein' me first 4" kit, ya bilge rat, shiver me timbers, arrr, me first impression was WOW! Blimey! There's somethin' very nice about bein' able t' get your hands into t' airframe t' work. Avast, me hearties, me proud beauty! Blimey! All t' parts listed in t' instructions were present, even an extra centerin' ring. Everythin' fit nicely with t' possible exception o' a very tight tube couple. Begad! Blimey! Blimey! Blimey! A little sandin' brought that little annoyance into line.

A few basics about t' kit: It has two 4" tubes. T' tubes are fairly sturdy and t' spirals are pretty shallow. Blimey! T' coupler fit nicely (if nay a little too snug). Begad! Avast, shiver me timbers, me proud beauty! T' nose cone is an old plastic ACE nose cone. Ahoy! It has two standard Aerotech 3/16" square plastic lugs. Well, blow me down! 1/4" lugs would have been nice and probably should be upgraded. Ahoy! Nay really sure what t' centerin' rings are made from. Aerotech has their own name for t' material, but they feel like a partial/slate composite. Ahoy! They are very sturdy. Aye aye! Ya scallywag! T' elastic shock cord is about 12' long. I be a little concerned about it bein' elastic, but it worked without a hitch. Ya scallywag! T' shock cord attaches t' t' top o' t' Labyrinth baffle like all t' other Aerotech kits and t' other end attaches t' an eye hook in t' bulkhead in t' upper section.

T' instruction were clear and concise for t' most part. Ya scallywag! (although a couple o' times I had t' re-read a step t' make sure I understood what they were talkin' about. Avast, me proud beauty! They had clear illustrations for most t' steps that made it very clear from a visual stand point. Ya scallywag! I didn't use any new construction techniques with this rocket that I haven't done before with t' exception o' only usin' epoxy. Begad! Begad! I didn't bother usin' CA in areas that they said t' use it. Begad! System 3 epoxy worked fantastic.

BackendAs designed, matey, on G motors, arrr, flights were a lot o' fun! Slow take off and low altitude are a lot o' fun for me so flyin' this rocket on G's be a blast. Ahoy! Begad! I realized very early on that I didn't want t' limit this bird t' only G motors. I decided that this be also goin' t' be me cert rocketry t' qualify level 1. Well, blow me down! Modifications were goin' t' have t' be made. I used t' "bonus" centerin' rin' t' add Kaplow Klips and left out t' motor clip and motor block. Begad! I used only System3 epoxy t' glue everythin' (quite liberally I might add). I will also glass t' pathetically thin fins for t' H and above flights.

Finishing:
Mine is nay finished yet, but I wanted a unique look, me hearties, so I am nay goin' t' go with t' recommended paint and decal scheme. Aye aye! T' decals are t' usual self adhesive decals that AT uses on all their kits.

Construction Rating: 4 out o' 5

LaunchFlight:
Built stock, it flies only on G's, but it fly's as designed on them rather well. Avast, me proud beauty! I have only flown mine on G64-4's so far and have nay had a single problem. Arrr! It be very stable, shiver me timbers, even in high winds (20mph). Avast! Begad! No weather-cockin' at all, no conin' or spiraling, no problems at all. In fact, in t' 20mph+ winds, arrr, ya bilge rat, it didn't cock into t' wind at all. Blimey! Ahoy! T' wind actually gently pushed it. Aye aye! Aye aye! On t' video tape, t' only effect o' wind you see be t' smoke from t' motor goin' smartly down range. Avast, me proud beauty! Arrr! T' rocket didn't even seem t' notice it at all.

5/00 Update:I successfully used t' G-Force in this review (with some modifications) t' get me Level 1 certification. Avast, me proud beauty! Blimey! It be fairly heavy when I was done modifyin' it (4lbs fully loaded), but flew perfectly on an H128. T' Cannonball Works RRc2 told me it hit 666 feet on a gusty and pretty windy day.

Recovery:
AT used their ever-popular "boin' cord" shock cord. Ahoy! It worked well even though I was concerned. Avast, me proud beauty! Ya scallywag! I will modify it even further by addin' bunched up tubular nylon around t' elastic for insurance. Ahoy! T' 36" parachute brought it down rather slowly. Arrr! In t' high winds, ya bilge rat, ya bilge rat, I had about a 3/4 mile walk t' retrieve it.

Flight Rating: 5 out o' 5

Summary:
When built stock, matey, this is a really fun bird t' build and fly. Well, blow me down! It has one really bad drawback that kept it's overall ratin' down in me eyes. Aye aye! It's price. Avast! If t' cash doesn't matter t' you, then this is a great rocket t' have in your collection, me hearties, but keep in mind that it's nay "the only fish in t' sea".

Overall Rating: 3 out o' 5

    Great flight for my L1 cert launch! Flies slow and smooth, lots of fun! Overall Rating: 5

  • Aerotech G-Force By Kyle Cornelius

    Large mid power model for low altitude flights. Very good materials except the coupler which needs to be beefed up Very quick assembly with major problems in construction. The instructions were pretty straightforward. The fins could be sturdier, but I have flown this rocket 10+ times with only a cracked joint. Very good major components. Finishing: Easy to finish, except for its size, ...

  • Aerotech G-Force By Darwin May

    Brief: The G-Force is a single staged, parachute recovered large model rocket. There were 2 4" body tubes that were made out of the AT tubing. I opted to design the rocket for a payload by not gluing the nose. It has 3 fins made of EXTREMELY thin plastic that look just like the Sumo fins. The motor mount was 24" by my best guess, and made from thick cardboard. The shock cord appears to be 12' ...

  • Aerotech G-Force By David Kneble

    This is a great mid-power flyer with two downsides, limited range of motors, high price. All the normal components: Two 4" tubes, an ACE nosecone, 42" parachute, bulkhead equipment, motor tube, CR's, baffle system, elastic 12' shock cord, fins. Instructions are very simple if you have built any other Aerotech kits. If not, then read through them and make sure you understand them. If you ...

This is my favorite rocket. It is loud, low and slow and allows me to use G motors in the small field I fly out of. After about ten flights, the elastic shock cord started showing signs of wear. Aerotech confirmed that it would be OK to replace the elastic with Tubular Nylon. I ended up replacing the 12-foor elastic shock cord with 24feet of 1/4-inch tubular Kevlar® from Giant Leap Rocketry. Small rubber bands kept all that TK from tangling when the recovery system deployed. It worked perfectly.

This is one totally awesome rocket. It was also my first MPR kit. I received it for Christmas. The kit was an absolute dream to assemble. I really was impressed with the fin-lok system and the ejection baffle. Sure beats handfuls of recovery wadding. I did however find the upper body wrap a real pain in the neck. First flight was on a G40-4W. Nice slow, straight boost with a perfect recovery. I highly recommend this kit. I do feel that the price could be reduced. Hobbylinc.com sells this kit for $88.59.

Why the reviewer gave a 4 out of 5 for this rocket is beyond me. This has got to be my favorite rocket out of about 40 in my fleet. It was my first 4” tube and I have flown it at least 12 times – G40’s and 80’s. It flies PURFECT every time, in all conditions, all weather – even gusty winds. The only change I made with to use tubular nylon instead of elastic. The G-Force is tough too. Have had some hard landings, where the fin sticks into the ground. Just clean it off and fly it again. If you want a great big rocket for small fields – this is it. I have other Aerotech kits and this is by far the best one. I think I am going to buy another one and replace the MMT with a PML Phenolic 38mm tube and fly it on H and I motors.

The G-Force has become my primary G-powered rocket. As someone else mentioned, it's loud, and can be flown in modest-sized fields. I do suggest one modification - upgrade the motor mount to 38mm to increase your motor options. This bird flies very nicely (and even louder) on Pro38 G's, and can easily handle the 2 grain H, with no reinforcing.
