T' Aura was me first rocket from LOC/Precision and I would consider it their entry level kit considerin' t' size, shiver me timbers, ease o' build and price. Arrr! Ahoy! It is a basic three-fin-and-a-nose-cone (3FNC) kit with a 29mm motor mount. 

Although t' kit comments indicate that t' "kit is recommended for those with previous model rocketry buildin' experience", ya bilge rat, it is a very easy kit t' assemble. T' experience is required due t' limited illustrations in t' instructions and probably due t' t' 29mm motor option.

T' kit includes a plastic nose cone, arrr, shiver me timbers, a section o' body tube, 3 pre-cut plywood fins, ya bilge rat, motor mount materials, a launch lug and t' recovery system.

CONSTRUCTION:

T' kit comes in a plastic bag with an insert displayin' a picture o' t' Aura and t' specifications. Blimey! Avast! Blimey! On t' back o' this 4x11" insert are t' instructions. Avast! Blimey! There are only two small illustrations. Ahoy! Blimey! One showin' t' aft view and another cut-away showin' t' side view motor mount and fin alignment. Ya scallywag! T' instructions are straight forward and in a logical order allowin' t' builder t' assemble this straight-forward 3FNC rocket.

For ease o' assembly and alignment, t' fin lines and launch lug lines are pre-drawn on t' body tube. Begad! Begad! A nice touch. touch. Arrr! This and t' simplicity o' t' rocket make it go together quickly. LOC recommends usin' epoxy (6 or 20 minute) and I used 15 minute.

T' recovery system is assembled from its own set o' instructions. Aye aye! It consists o' a length o' braided nylon cord which is knotted at both ends, me hearties, and knotted with a 1" loop in t' center. Ya scallywag! Ya scallywag! T' two knotted ends are taped t' t' inside o' t' body tube with t' knots on t' far side o' t' tape. Avast, me proud beauty! Then it is coated with epoxy t' completely cover t' tape and t' knots. Arrr! Begad! T' top o' t' nylon with t' 1" loop sticks out o' t' top o' t' rocket and is used t' tie t' elastic shock-cord to.

T' motor mount consists o' a 29mm tube and two centerin' rings. Ya scallywag! Aye aye! T' kit relies on friction fit for motor retention. Aye aye! Avast, shiver me timbers, me proud beauty! retention. Avast! I added a piece o' sprin' steel (from an old windshield wiper blade) t' make a retention hook just like an Estes kit.

[Rocket Picture]Finishin' was also quick, arrr, by choice, since it was two days before NARAM-40 and this rocket was goin' along. Well, blow me down! Ya scallywag! I used Plasti-Kote primer for sealin' and filling. Ya scallywag! Avast, shiver me timbers, me proud beauty! I then painted t' entire rocket with some left-over red paint, ya bilge rat, matey, then masked and added silver paint.  I lastly hit it with clear coat. Blimey! Avast! Aura does nay come with any decals so t' finish is entirely up t' you.

Overall, shiver me timbers, me bucko, for CONSTRUCTION I would rate this kit 3 points.It is easy t' build and therefore similar t' many other 3FNC rockets. T' instructions were clear and t' addition o' t' shock-cord instructions ensure a successful attachment. Ya scallywag! It would be nice t' see a decal with t' name o' t' rocket and a positive motor retention system.

FLIGHT/RECOVERY:

T' Aura is a bit deceptive. Begad! Its size and looks may make observers think it is an Estes-type kit weighin' in at 2 - 3 ounces. However, with t' motor this kit weighs in around 12 ounces.

T' Aura was launched at NARAM-40, shiver me timbers, me bucko, as planned, on an EconoJet F20-7. Begad! Out o' sight flight, with simulation indicatin' greater than 3800 feet. Aye aye! Begad! It came down very fast as t' nylon streamer be spinnin' and wrappin' itself up. Ya scallywag! Arrr! It landed only 50 feet from t' pad it was launch from. Arrr! Arrr! Upon inspection, arrr, one fin had broken completely off takin' all o' t' epoxy bonded areas with it.

Later I tried usin' t' streamer from t' Aura on an Aerotech Mustang, only t' find t' same type o' rollin' and tanglin' on its way down. Avast! Maybe it was all t' humidity, ya bilge rat, but t' streamer did nay seem effective.

T' fin comin' off may be somethin' t' watch out for, because I have read several posts on RMR regardin' t' Aura indicatin' t' same thing. I think usin' t' technique o' pin holes along t' alignment line would be recommended. Begad! I use a variation t' this technique by usin' a hobby knife t' cut 1/4" slits across and perpendicular t' t' alignment line, arrr, arrr, spacin' them about 1/4" apart. This allows t' epoxy t' flow into t' body tube and gives it better hold. Well, blow me down! Ahoy! This was done when reattachin' t' fin.

After replacin' t' fin, I flew t' Aura on an Aerotech RMS E23-5T. Aye aye! Avast, me proud beauty! Simulation indicates that it should fly t' about 1550 feet. Ahoy! It was a beautiful launch and very straight flight. Begad! Watchin' it arc and start t' scream toward t' earth was nay expected though. though. Neither be it slammin' into t' ground somewhere out o' sight and nay t' be found. Blimey! Well, blow me down! Total loss included t' $20 rocket, arrr, t' $35 casing, me bucko, t' $14 parachute (I should have had that streamer in there) and t' time t' get this rocket ready t' fly.

T' meanin' o' Aura is:

                 1.a distinctive and pervasive quality or 
                       character; air; atmosphere: an aura of 
                       respectability.
                  2.a light or radiance claimed t' emanate 
                       from t' body and t' be visible to 
                       certain individuals with psychic or 
                       spiritual powers.
                  3.a sensation, matey, me hearties, as o' a glowin' light or an 
                       aroma, precedin' an attack o' migraine 
                       or epilepsy.

I think t' 3rd definition was appropriate considerin' t' migraine that ensued after realizin' t' "cost" o' that flight. Arrr! Blimey! O' course it be nay a rocket design or kit issue.

For FLIGHT/RECOVERY, I would rate this kit 3 points.T' streamer seems t' be t' main issue and because RMR postings indicated experiences o' losin' a fin and then it happened t' me, arrr, arrr, thar be probably reason t' consider its recovery system as t' reason. Avast! Also, motor retention would be a bonus.

Overall, me hearties, shiver me timbers, this kit is easy t' build and is a nice flyer which can give very high altitudes. Begad! Consideration on fin attachment and streamer usage will need t' be taken by t' modeler. Well, blow me down! I give t' kit an OVERALL ratin' o' 3 point

The LOC Aura is a very durable kit. I have found that by making the fins through the wall to be the best way of keeping them on during landing. This worked very well under flight. I had launched this rocket in NY during Colboskil on a G125. I did not recover it due putting a large chute in it.

The fiberglassing of the fins is a absolute must. I flew mine at Danville 99 on an AT G-80 SU. Thank goodness for bonus delays. The Aura is not what I would consider a good beginner kit. I think the previous rocket building experience warning is a good call.

The LOC Aura is one of my favorite rockets. Easy to prep and always an impressive flight. However, my first flight was with the included streamer. It hit the playa hard and delaminated the body tube at one fin. Easy to fix with epoxy. But I fly it now with a small nylon parachute (12-15 inches). One change I made to the kit was to add an AeroTech motor retaining clip. I had to cut a small rectangle of airframe to make this work. I wouldn't recommend doing this. It limits the available motors, and the retention doesn't always work. But I would recommend the rocket. It's a great kit.

I enjoyed building the LOC Aura. A nice small rocket, that really soars. I asked a lot of people on the Internet wether to use the stock streamer or not, half said yes, half said no. I went with the streamer, and now I regret it. I broke a fin off, and the soil was a soft as could be. Next time I will be using a small chute, but the streamer would still be good for a F or G launch, if I am ever tempted. Overall a great rocket, quality parts, and should last for a long time, if the fins stay on. Would love to see it fly on a G40 or G33 sometime, but good luck to that crazy person.

When somebody launches a big one, heads pop up during climb-out. With Aura on a G40, people can sense that something special is underway; she climbs and climbs, and nobody stops watching. Oh, yeah; this kit is what it's all about.

I have flown my Aura several times from a high altitude launch site 8800' MSL with motors at the upper end of the range (G33s and G64s). I worried about the fins when I built the kit, so I reinforced the joints with 0.5 oz glass on the bias. (0.5 oz cloth was used to keep the weight down my bird tips the scales at 8 oz. with a 24" chute and NO MOTOR) When you use "regular" glass (Not Crowfoot) on a bias (fibers running at 45 degrees to the rocket) you have two advantages. First all the glass fibers are working for you because both the long and cross fibers cross the joint. Second is that the cloth is pliable in that direction so it goes around corners better. The other thing that is really important when glassing LOC paper tubes is to sand the waxy finish off of the tube so the epoxy can penetrate into the tube, and have some "tooth" to bond to for maximum strength.

I love my Aura and have flown it many times using both D and E engines (with homemade motor adapter). It flies great on a E15-7 and the grand-kids love the noise and smoke. Easy to build and nice kit to get one started into mid power rockets. Plan on flying it with and F this season but will switch out the streamer for a small parachute. Great kit, great rocket and I highly recommend it for someone just getting started into the Mid/high power rockets.

My 1st mid-power rocket kit. I agree with all of the earlier posts. Gotta' have good fin fillets or you're going lose a fin. I have installed a quick change swivel to change back and forth between streamer or 12" chute. This rocket really climbs out on an E motor, but looks good on a D also. Haven't tried an F or G yet (may not come back!)

The Aura is a fun kit to fly. On a G-80 it is a spectacular flight, but almost impossible to track near apogee, and I've nearly lost it a couple of times. I fly mine with a piece of flame proof wadding filled with chalk dust, so at ejection it makes a nice white spot against the clouds and I also have but in a 20 foot streamer. Even at 4200 feet it is easy to track its descent.

Don't fly it on an E9! By the time it was stable, it was flying in a distinctly horizontal fashion. The rocket gods were kind and I found it just across the road from the field.

I bought my Aura over ten years ago and it's still flying like a champ! The only modification I made was to scrap the streamer and put in a 10 inch nylon chute. This bird is HEAVY and if you go with a streamer you're begging the rocket gods to take a fin!

I've flown my Aura now at least a dozen times and have had only one fin breakage on the second flight. I found that by attaching the supplied streamer by the very end (so you have a long single streamer) and by folding several times before rolling it works quite well. During times of high humidity I've been known to sprinkle the streamer with some baby powder - which also gives a nice marker at ejection. I've moved on to bigger and better rockets, but still fly my Aura every chance I get. For small field it flies great on D12-3 or E15-4 and grandkids love watching it fly and chasing it (which is a bonus for me ) Great little rocket that I highly recommend.

I love the Aura. It's a hot little rocket. I once had it caught in a flag pole. Had to cut the shock cord. I've chipped a fin and broken a few fins but it's okay. I've flown it on an Ellis F37 or something. Straight and true. A little spinning on ascent. I was actually able to track the rocket all the way up! Streamer popped. It was heading toward the danger zone behind the military target range. Luckily the wind caught it and brought it back within 50 ft. I plan to fly it on a G later!
