Quest MLAS

Brief:
This is semi-scale sport model based on NASA's Max Launch Abort System (MLAS). Well, blow me down! It is quite stubby, shiver me timbers, bein' 3.5" in diameter and a mere 9" long. Avast! Aye aye! It has only one recommended motor, arrr, me bucko, t' B6, and recovers in two parts on three parachutes.

NOTE: Two RockSims were submitted. Blimey! One be t' stock build and one has added nose weight. Blimey! Well, me bucko, blow me down! Blimey! You should assess the stability o' your own model.

Construction:

Parts included in t' kit:

  • One 3.5" D v 5.5" L tube
  • One nosecone shoulder ring
  • Three laser cut rings for t' motor mount and nose cone shoulder
  • 18mm motor mount (tube, block hook)
  • Keelhaul®©™® and elastic cords
  • Three plastic 'chutes
  • Two sets o' four laser cut fins
  • 1/8" lug
  • Lag bolt
  • Decal set
  • Two foam MicroMaxx cones

T' build requires t' standard sandpaper, me bucko, hobby knife, me bucko, matey, wood filler, wood glue. Foam safe white and black paint is also needed.Quest MLAS

T' 10 pages o' instructions are well written and are excellently illustrated. Arrr! They include a markin' guide for t' motor mount, me bucko, a ruler that you can cut out if you don't have one lyin' around and, o' course, arrr, shiver me timbers, a fin markin' guide. Begad! Avast, me proud beauty!

T' parts come securely packaged in a box vs. Ahoy! a plastic bag. Blimey! Blimey! This protects t' wide, me bucko, me hearties, thin walled body tube, and helps both you and t' environment. Ya scallywag! Avast, shiver me timbers, me proud beauty! T' box can be recycled into a reusable range box. At least, arrr, ya bilge rat, so sayeth t' sticker on t' end. Avast, me proud beauty! Arrr!

T' motor mount assembly is standard, usin' both a thrust rin' and a motor hook. Two centerin' rings are provided. T' lower rin' has cutouts t' save a some weight. Avast! T' Keelhaul®©™® cord is tied t' t' mount prior t' t' installation o' t' top ring. Blimey! I used a *small* dab o' 5-minute epoxy t' secure it.

T' body tube is quite thin for its size and I had concerns about squashin' it along t' way. I'm glad t' mount didn't grab while I was insertin' it into t' glue smeared tube. It survived me clumsy buildin' skills but concerns about flight durability remained.Quest MLAS

T' fin preparation and installation are also typical - sand, mark, glue (double glue joints are specified). Arrr! Avast! The instructions have t' fins filled after they are installed but I prefer t' do this prior t' installation.

T' nose cone assembly consists o' t' foam capsule, ya bilge rat, shiver me timbers, matey, a shoulder and a laser cut cardboard bulkhead. Begad! A heavy lag bolt is installed in t' tip t' provide t' required nose weight. Avast! This bolt is also t' attachment point for t' nose cone's parachute. Arrr! A second, very thin Keelhaul®©™® cord is tied around t' bolt and is fed into t' body when t' 'chutes are installed. Well, blow me down! Attachin' t' cord t' t' bolt should keep all t' parts together on recovery and will allow t' cone t' come down base first. T' final step is to install t' faux thrusters on t' nose (which were faux on t' real thin' too). Begad! Avast, me proud beauty! Here, you split t' two foam MMX cones, sand t' fit, and glue them on t' capsule.

Finally, shiver me timbers, matey, matey, you also have t' assemble and install t' three plastic 'chutes. Blimey! I added a length o' elastic t' each of t' nose cone 'chutes t' act as separate risers.

Finishing:
Prior t' painting, you are instructed t' fill t' cone with thinned wood filler, me bucko, which I did. Ahoy! Blimey! T' entire model is then supposed t' be painted with foam-safe paint. Ya scallywag! Avast! Blimey! I chose t' paint t' lower part with 'regular' paint and t' cone with brush-on acrylics. I ended up usin' t' paint that I had on hand.

T' body was spray painted and t' fins were painted with brush-on. I don't like sprayin' such small areas. Aye aye! The instructions also say t' cover t' entire body with a plastic bag, expose t' fins and mask them off. Blimey! Since I didn't spray them, me hearties, I just masked with plain old blue maskin' tape.

Maskin' t' cone was t' most complicated part o' t' process for me since t' surface o' acrylic paint be not perfectly smooth and I had a fair amount o' bleeding. Avast, me proud beauty! I should have painted on a layer o' t' base coat before adding t' black trim.

T' kit provided quite a few decals includin' stripes, rivets, me bucko, fin numbers and logos. T' instructions do a great job showin' where t' position them. Ya scallywag! Begad! I HATE IT when you have a sheet o' decals and have t' guess where they go. Ya scallywag! Make sure you look at them carefully t' separate t' individual items (for example, me bucko, t' numeral 'I' decals were individually positioned on t' paper but some o' t' other numbers were attached t' one another). T' decals were tough and came off their backin' smartly and easily. Ahoy! Begad! As usual for me, ya bilge rat, I had some positionin' problems and little ones tended t' stick immediately. Blimey! Well, blow me down! I'll chalk this up t' operator error.

T' overall results are that t' rocket looks great as long as you back far enough off. Well, blow me down! But I like it! All these issues are mine and nay t' kit's.

Construction Rating: 4 out o' 5

Flight:
Prep be more complicated than your typical LPR bird. Well, me hearties, blow me down! I added t' specified waddin' and laid in t' 'chutes in the order specified. Blimey! Avast, me proud beauty! T' body's 'chute went in first followed by t' two capsule chutes. I opted for t' B6-4 vs. a -2 because that's what I had. Avast, me proud beauty! Begad! My RockSim model, arrr, which uses t' as-built mass and CG, says t' -4 was a better fit anyway.Quest MLAS

Well, shiver me timbers, it rose about 20' then arced over and core sampled. It's path seemed t' be perpendicular t' t' 7-8 mph winds. T' good news: t' soft foam cone be muddy but nay dented, shiver me timbers, t' body tube was intact and all 8 fins stayed on. T' ground was soft but t' kit was sturdier than I expected.

I wanted t' try an Estes C6-5 but was nervous about usin' a heavier motor, so I kludged up some nose weight. Arrr! Blimey! I won't embarrass myself with t' details but it DID involve bubble gum (but no bailin' wire or duct tape). Begad! Blimey! Avast, me proud beauty! Blimey! In me haste, I didn't check t' CG for future reference. Begad! Blimey! Arrr! Blimey! T' boost was good with some weather cocking. Begad! Blimey! Avast, me bucko, me proud beauty! Blimey! Success! Blimey! T' nose weight unit was lost at ejection but I since recreated it as best I could. Ya scallywag! Blimey! It was around 0.3 oz.

Recovery:
Ejection on flight #2 be a bit late due t' t' weather cocking, shiver me timbers, but nay bad. Avast! Blimey! Ya scallywag! Blimey! One o' t' two nose cone 'chutes tangled, but one is enough for a soft landing.

Flight Rating: 2 out o' 5

Summary:
I liked short stubby rockets and fell in love with t' MLAS after seein' its launch photos and videos. Ahoy! This is a very semi-scale representation, ya bilge rat, but I like it too! Quest MLAS

T' motor mount, laser cut fins, and recovery system are fairly standard. Arrr! Paintin' is a little more complicated than most, but I seldom consider finishin' when I think o' skill levels. Begad! Avast, me proud beauty! There are a lot o' decals and their quality is good. Ahoy! T' three 'chutes make prep a little more complicated, me bucko, but still nay difficult. Ahoy!

T' negatives are a thin walled body and marginal stability. Ya scallywag! Ahoy! Quest will likely say that me buildin' skills or the wind led t' t' problems with t' B6 flight. Ya scallywag! Avast, shiver me timbers, me proud beauty! Even with these issues I like t' kit and it was refreshin' t' see someone go out on a limb and offer such a kit. Despite me low rating, I recommend buyin' one..or two. Aye aye!

I have added some weight t' me nose and will try her again at t' next launch. Avast, me proud beauty! I went ahead and submitted the review since this could take a while.

    My son and I were on our most recent trek up to Stevensville to see Dave at Red Arrow Hobbies ( http://www.redarrowhobbies.com/ ) to pick up some kits he had ordered up for us for a Cub Scout build event. My son was cruising through the inventory, and yes it is nice to have a ‘real’ rocket/hobby shop to actually physically walk into, checking out all the different kits and ...

I think I need to point out a couple of points about the B6-4 flight that may have led to my low launch rating. First, it was on the windy side and was probably pushing 10mph. Another point which I remembered but forgot to log is that the rod was really cruddy and I suppose it could have affected the boost. So, take my rating is one data point and wait for other results.
