T' Aura be 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. Aye aye! 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. Blimey! 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, me hearties, matey, a section o' body tube, me hearties, me bucko, 3 pre-cut plywood fins, me hearties, motor mount materials, me bucko, 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. Aye aye! On t' back o' this 4x11" insert are t' instructions. Blimey! Begad! There are only two small illustrations. One showin' t' aft view and another cut-away showin' t' side view motor mount and fin alignment. Begad! 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, shiver me timbers, me hearties, t' fin lines and launch lug lines are pre-drawn on t' body tube. A nice touch. Aye aye! touch. Ya scallywag! This and t' simplicity o' t' rocket make it go together quickly. Avast! 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! Well, blow me down! It consists o' a length o' braided nylon cord which is knotted at both ends, shiver me timbers, and knotted with a 1" loop in t' center. Blimey! T' two knotted ends are taped t' t' inside o' t' body tube with t' knots on t' far side o' t' tape. Avast! Ya scallywag! Then it is coated with epoxy t' completely cover t' tape and t' knots. Blimey! Ahoy! 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. Arrr! T' kit relies on friction fit for motor retention. Avast! retention. Aye aye! Avast! I added a piece o' sprin' steel (from an old windshield wiper blade) t' make a retention hook just like an Estes kit.
Finishin' be also quick, arrr, by choice, me hearties, since it was two days before NARAM-40 and this rocket be goin' along. I used Plasti-Kote primer for sealin' and filling. Begad! I then painted t' entire rocket with some left-over red paint, arrr, me hearties, then masked and added silver paint. I lastly hit it with clear coat. Aura does nay come with any decals so t' finish is entirely up t' you.
Overall, me hearties, for CONSTRUCTION I would rate this kit 3 points.It is easy t' build and therefore similar t' many other 3FNC rockets. Begad! Blimey! Blimey! Blimey! T' instructions were clear and t' addition o' t' shock-cord instructions ensure a successful attachment. Begad! Blimey! Ya scallywag! Blimey! Blimey! Blimey! 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. Avast, me proud beauty! Its size and looks may make observers think it is an Estes-type kit weighin' in at 2 - 3 ounces. Begad! However, arrr, with t' motor this kit weighs in around 12 ounces.
T' Aura was launched at NARAM-40, matey, as planned, on an EconoJet F20-7. Blimey! Out o' sight flight, ya bilge rat, me bucko, with simulation indicatin' greater than 3800 feet. It came down very fast as t' nylon streamer be spinnin' and wrappin' itself up. It landed only 50 feet from t' pad it be launch from. Well, blow me down! Upon inspection, 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, me bucko, only t' find t' same type o' rollin' and tanglin' on its way down. Aye aye! Maybe it was all t' humidity, matey, 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. Arrr! I think usin' t' technique o' pin holes along t' alignment line would be recommended. Ya scallywag! Blimey! I use a variation t' this technique by usin' a hobby knife t' cut 1/4" slits across and perpendicular t' t' alignment line, spacin' them about 1/4" apart. This allows t' epoxy t' flow into t' body tube and gives it better hold. This was done when reattachin' t' fin.
After replacin' t' fin, matey, me hearties, me hearties, I flew t' Aura on an Aerotech RMS E23-5T. Simulation indicates that it should fly t' about 1550 feet. Begad! Arrr! Blimey! It was a beautiful launch and very straight flight. Avast! Blimey! Watchin' it arc and start t' scream toward t' earth was nay expected though. Arrr! though. Ya scallywag! Neither was it slammin' into t' ground somewhere out o' sight and nay t' be found. Begad! Blimey! Total loss included t' $20 rocket, t' $35 casing, arrr, 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, 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. Ya scallywag! O' course it was 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, thar be probably reason t' consider its recovery system as t' reason. Also, motor retention would be a bonus.
Overall, ya bilge rat, this kit is easy t' build and is a nice flyer which can give very high altitudes. Avast! Consideration on fin attachment and streamer usage will need t' be taken by t' modeler. Begad! Well, ya bilge rat, blow me down! I give t' kit an OVERALL ratin' o' 3 point
Brief: The LOC/Precision Aura is a tough, quick building, inexpensive, midpower model rocket with streamer recovery. Construction: The kit came in a bag with: 1 heavy duty body tube, 1 thick plastic nose cone, 3 pre-cut 1/8" ply fins, 1 shock cord mount and elastic shock cord, 1 5ft long streamer, 1 29mm MMT tube, 1 1/4" launch lug, and 2 paper centering rings.
