Brief:
Loki's line o' 38mm reloadable motors. Begad! Cheapest o' t' 38mm reloadable options for both hardware and reloads. Avast! Begad! Blimey! Currently, arrr, only t' H144, I405, and J528 loads (Loki White propellant) are available for these motors, but more formulas and motor designations are comin' out soon.

Construction:
Currently available be t' Loki 240, arrr, matey, 480, matey, arrr, and 740 motor. Each motor comes with a quality case with external snap rin' (thrust ring), shiver me timbers, graphite nozzle, shiver me timbers, ya bilge rat, nozzle washer, matey, arrr, forward bulkhead, and snap rings. Avast, me proud beauty! Well, blow me down! If you buy t' system package, you will get a forward closure for each motor. Begad! You don't have t' share t' closure.

A typical Loki reload comes with a spiral wound phenolic liner, ya bilge rat, propellant grains, delay grain, two large O-rings, six small O-rings, me hearties, arrr, and a red cap (or vial) that contains 1.5 grams o' black powder. Blimey!

An interestin' thin' about t' Loki reloads be t' number o' grains in the reload kit. T' H144 uses 4 ~30 gram slugs, and t' I405 (naturally) uses 8 ~30 gram slugs. Blimey! T' J528 breaks t' trend, me hearties, matey, usin' six ~60 gram slugs. Loki's goal was t' create loads that can be shipped parcel post, matey, so they made t' grains 30 grams. Begad! However, interestin' things happened when t' motors got too large using the smaller slugs, matey, shiver me timbers, so this be nay an option with t' 740 motor. Begad!

Assemblin' t' Loki motor is very similar t' Kosdon and AMW motors. Aye aye! Begad! Blimey! This be t' order that I build them. Begad! Avast! Blimey! I start out by greasin' t' two large O-rings and placin' them in t' slot in t' nozzle and bulkhead. Aye aye! Ahoy! Blimey! Of course it is important t' make sure you use t' correct nozzle for t' load you are using. Well, shiver me timbers, blow me down! Blimey! T' nozzle conveniently has a number scratched into t' side that corresponds t' t' reload instructions. Aye aye! Aye aye! Blimey! Set t' closures aside so they don't get dirty, matey, me bucko, damaged, or lost.

Then it is time t' build t' delay column. Begad! Simply stack t' six smaller O-rings over t' delay element then place it on a flat surface and press the forward bulkhead onto it so t' delay grain goes into t' delay well. Well, shiver me timbers, blow me down! I then use a blunt tool t' push t' O-rings in all t' way. Blimey!

Once this is done, matey, arrr, you have t' option o' trimmin' t' delay. Avast, me proud beauty! Begad! It is a good idea t' use t' Loki-DAT tool for this. Aye aye! T' Pro38 DAT tool would work also. Leavin' t' delay grain untrimmed will yield a 17 second delay. Avast, me proud beauty! T' DAT tool will allow you t' trim it t' 13, ya bilge rat, 10, me bucko, arrr, 8, or 5 seconds. Avast, me proud beauty!

Insert t' forward part o' t' nozzle into t' liner. Then stack in the propellant grains followed by t' aft end o' t' forward closure. Avast, me proud beauty! Begad! Grease up the inside o' t' case, me hearties, and t' liner tube. Ya scallywag! This will make t' next step easier, me hearties, and you will be thankful for t' grease when it comes time t' remove the spent components, trust me. Begad! Well, blow me down! Press t' assembly into t' motor case (nozzle should be at t' end with t' thrust ring) until t' nozzle is about a quarter inch from t' snap rin' slot. Begad! Insert t' nozzle washer, followed by t' snap ring. Ya scallywag! Make sure t' snap rin' is in t' groove by lightly squeezin' t' pliers and rotatin' t' motor. Avast! Avast!

Turn t' motor over and press down on t' forward closure t' press the nozzle and washer onto t' snap ring. Well, blow me down! Install t' final snap ring, makin' sure the snap rin' is in t' groove. Finish t' motor construction by installin' the ejection charge (if you want t' use it). Arrr! Begad! T' forward closure gives you generous space for t' ejection charge, so pour in as much as you need. Ya scallywag! Ya scallywag! Then take some waddin' and place it on top o' t' charge. Well, me bucko, blow me down! Then press on t' red cap t' hold everythin' in place. Begad! T' waddin' is thar t' hold t' powder against t' delay column.

Flight:
To ignite t' motor, arrr, I used a Magnelite igniter with a single fold. Begad! Avast! Ignition is quick and t' motor produces a bright white flame and tons o' white smoke. Avast, me proud beauty! Of the two motors I flown, arrr, t' I405 was me favorite! I had t' pleasure t' see several I405 flights, and it has a loud and unique sound t' it! After a launch of a Big Brute with one, ya bilge rat, Carl Tulanko asked me, "What was that?" I told him a Loki I405. Ahoy! Aye aye! Later on durin' t' day, me hearties, I had me PML Aurora loaded with one and asked if he wanted t' come t' t' flight line and watch it fly. Avast! He said "No way! That motor is scary." It's a very impressive motor. Arrr! I only got t' see one J528 flight up close. Ya scallywag! If you like t' J350 and t' J570, shiver me timbers, matey, me hearties, then you would love this motor! Lots o' umph!

Recovery:
Cleanin' o' t' Loki motor is identical t' that o' t' AMW and Kosdon motors. Remove t' snap rings, arrr, and press on t' bulkhead t' press t' components out of the case. Aye aye! Suggested tool t' use is a wooden dowel t' push out t' closure (or nozzle, if you t' use t' other end). If you are fortunate (and remembered to generously grease t' liner), everythin' should come out with minor effort. However, if t' rocket had an impact o' any kind, arrr, one o' t' bulkheads would mash itself into t' liner, makin' removal a chore. I used Baby wipes t' clean mine, me hearties, which worked surprisingly well.

Summary:
I am really pleased with t' Loki 38mm product. Aye aye! I mentioned that it is cheaper than other brands. Avast! Well, blow me down! Let's compare with this simple chart. Well, blow me down! Prices are retail list and comparison is done with Aerotech White Lightning, matey, Pro38 standard, ya bilge rat, ya bilge rat, and Loki loads.

^** - Pro38 motor hardware is just a tube. There is no closures. In a sense, Pro38 motors are disposable motors that are held together by the case.

Another interestin' comparison be t' total impulse o' t' loads for the cases and how much they cost t' fly per total impulse. This comparison based off data from t' NAR/TRA/CAR combined list. Avast! Begad! All numbers have been rounded to nearest whole cent. Begad! Begad!

In t' near future, me bucko, me hearties, Loki will be offerin' new loads for their motors. If you like fast burning, "kick 'em in t' butt" loads, then you will enjoy their Blue Formula which will debut with a H294, I605, and me soon t' be favorite, ya bilge rat, shiver me timbers, J1001! Also in t' works are two moon burnin' loads that utilize their White formula. Arrr! I can't wait t' try out their I124 and J192 loads! Those loads have close t' a 4 second burn!

What I would like t' see in Loki's 38mm line is a 360 and 600 motor. Aye aye! I can imagine a 360 load priced at around $24.99 and a 600 load bein' a reasonable $34.99. Ya scallywag! I would also love t' see Black and Spark loads introduced too. Well, blow me down! I would have t' problem decidin' which loads t' buy!
