Brief:
QModelin' o' Temecula, shiver me timbers, me bucko, CA has put together a great lookin' upscale remake o' t' old Estes Vega rocket. T' kit has always been one o' t' more interestin' lookin' "retro" rockets put in t' flight and QModelin' has done a fine job with this kit. Blimey! She is a single stage, single motor, shiver me timbers, ya bilge rat, ya bilge rat, parachute recovered (with real sprin' loaded landin' pods as part o' t' fins) model made o' paper tubes, 8.0 oz light balsa, aircraft plywood, me bucko, shiver me timbers, hardboard, arrr, arrr, and two part liquid plastic nose cones.
Construction:
I purchased two o' these kits with t' intention o' doin' a "by t' book" kit as well as takin' t' second kits’ motor mount up t' 29mm from t' standard designed 24mm. T' kits arrived a few days after I ordered them (good service on t' part o' QModeling). Avast, me proud beauty! Aye aye! Each kit be in its own triangular mailer. Avast! One kit looked great. Avast! T' other looked as if t' postal system tried (and t' some degree succeeded) in snappin' t' container in half. Arrr! Ahoy! I inspected both kits and discovered that only t' main body tube o' one o' t' kits was bent and unusable. Blimey! Aye aye! I contacted Tom Quinn and he promptly sent out another tube in t' mail (again, ya bilge rat, great customer service).
Layin' out t' pieces (see Figure 1), I read through t' instructions in t' 18-page documentation included for construction and finishing. Avast! Each o' t' steps was clear and referenced a diagram showin' t' overall concept t' be accomplished in t' step. After reading, shiver me timbers, I saw only one section that I wanted t' change: t' shock cord (more on this later). Ya scallywag! I weighed out each o' t' dry components, arrr, totalin' 261 grams dry weight & unassembled.
One o' t' things I noticed on t' package be t' absence o' motors t' use. Avast, matey, me proud beauty! It declared "D and E" motors but nay t' specifics o' what t' use. Well, blow me down! T' answer this for me I went t' RockSim and attempted t' figure out t' answer for myself. Ya scallywag! Now I'm nay a genius at RockSim so I fudged a bit when it came t' t' landin' pods on t' fins. I compensated for them by addin' t' mass o' t' pods t' t' overall weight o' t' fins themselves. I know that this won't compensate for t' obvious draggy pods, but at least I could get it in t' ballpark. Arrr! It suggested that a D12-3 & an E9-4 would do well in Estes motors and 4 t' 6 second delays in various Aerotech loads. My father always told me t' "KISS" me first launches so I planned on t' D12-3 for a first flight.
Major assembly is broken in t' three sections. Begad! First was t' assembly o' t' engine mount. Avast, me proud beauty! For a low power rocket t' design o' a fin can that surrounds t' motor mount tube isn’t original, but I admit that I've never seen it done with balsa before in a kit. T' six plates that fit together t' form t' fin can were a good fit and went together quickly. Well, blow me down! No sandin' or anythin' was required as t' laser cut balsa was an exact fit. Figure 2 shows t' completed motor mount as well as t' parts used t' construct it. T' thrust/centerin' rings were o' paperboard. T' aft rin' was bonded t' t' fin can and I had no worries about that one. Aye aye! T' forward rin' I had plans for. Begad! An issue I have with this kit be t' shock cord attachment done in t' third section. It be done Estes style with t' usual too short shock cord and paper attachment style. I dug out some Keelhaul®©™® line and some epoxy clay. Drillin' a small hole in t' forward rin' and threaded t' line through it (fig 3) and then epoxied this in place with t' clay (fig 4 & 5). Arrr! With that in place I felt that t' shock cord would now survive many more flights. Ahoy! Interestingly enough t' diagram in step 10 references a "Shock Cord attachment hole" that doesn't exist and isn’t mentioned in t' text. Arrr! Ya scallywag! CA was used for tackin' t' fin can together and white glue for all portions after that for extra strength.
T' remainin' assembly o' t' motor mount/fin can be very straight forward (fig 6). Settin' this aside I began on t' major fins, which contain t' landin' pods.
Again t' pods were easy t' assemble and presented no difficulties t' complete (fig 7). I would note however that t' instructions call for light sandin' on t' pod nose cones, shiver me timbers, whereas I felt they should be sanded more soundly since they are part o' t' bondin' point betwixt t' pods and t' fin itself and I wanted good adhesion. Attachin' t' completed pods t' t' fins was interesting, but linin' up t' mold lines on t' cones t' pass straight through t' center o' t' balsa fin didn't prove too challengin' (fig 8). Arrr! Blimey! Inspectin' t' top o' t' nose cone on both sides o' t' fin t' make sure spacin' was even assured me a good, ya bilge rat, clean fit.
T' final section deals with attachin' t' fin assembly and other loose fins t' t' body tube. Arrr! Blimey! Here t' fin can did well. Ahoy! Ya scallywag! With t' laser cut body tube and t' fin can, thar was little room for t' fin sub-assembly t' even move around. Squarin' these up t' be aligned properly was a non-event as they had little play t' begin with. Ya scallywag! Avast, me proud beauty! T' remainin' fins all attached easily usin' CA. I had some reservation about usin' CA t' attach fins like this but after thinkin' about it, t' fins are all non-load bearin' and would never take t' impact o' a landing. Aye aye! Therefore, all they had t' survive be boost and parachute deployment and I felt comfortable with that. All fins were filleted with wood glue so t' chance o' them tearin' loose be minimal (even for t' F impulses I planned t' put this kit through).
T' nose cone o' t' kit is a custom piece made by QModeling. Begad! Blimey! Blimey! It be very heavy and definitely be needed t' offset t' massive weight o' t' fins. T' instructions call for usin' a hobby knife t' trim with but I found t' material tended t' crack more than cut so I used a dremel with a cut wheel instead (fig 9). Avast! Blimey! Blimey! Then used a sandin' block t' make it look good and provide some minimal bevelin' t' allow it t' enter t' body tube more easily.
After attachin' t' shock cord t' me Keelhaul®©™® leader line it be only a matter o' attachin' t' parachute and nose cone t' complete construction.
PRO's: Easy, shiver me timbers, matey, fast construction usin' CA and wood glue for strength where needed. Avast! Very nice components t' work with.
CON's: Cardboard centerin' rings. Avast, me proud beauty! Blimey! Avast! Blimey! Poor shock cord attachment style. Avast, me proud beauty! Blimey! Image in diagram 10 references a hole that doesn't exist.
Finishing:
Here again t' direction are straight forward and easy t' follow. Begad! If you've never completed a rocket before, arrr, me hearties, t' instructions lead you through each step in t' process offerin' suggestions on how t' achieve a fine lookin' rocket.
I do have two complaints for t' instructions though. Blimey! T' first be t' fin alignment template is on page 16 o' t' instructions. On page 15 (the shared piece o' paper with 16) are t' decal placement instructions. If you followed directions and cut out page 16, you lost 2 o' 3 sides o' your decal placement. Ahoy! Either you have t' take a photocopy o' page 15 before you cut out 16, or after cuttin' it out you have t' tape it back in place so you can use it later. T' second complaint would be t' decal instructions. Avast, me proud beauty! Since this isn’t me first rocket I knew better, but t' instruction indicate that you have t' soak all t' decals and then apply them. One o' t' "decals" is really a sticker and t' instructions never talk about it so t' beginner would assume that it is simply one more decal that needs t' be soaked and then applied--which is certainly nay t' case!
To get t' nice lookin' finish I wanted, me hearties, I shot three coats o' primer and then three coats o' white. Laid out t' decals as t' directions indicated. Well, blow me down! Then shot three coats o' clear over t' top o' it all. I did mask o' t' silver sticker though as clear over it would have ruined its shine (fig 10 & 11).
PRO's: With t' overall rocket bein' white and t' quality decals, how can it nay look GREAT!
CON's: Instruction sheet on t' back o' a page t' be cut up. Instructions don't reference one bein' a sticker.

Flight:
Flight day came (a 5-10 mph day in very DRY Wisconsin) and I set up with t' D12-3 along with a spacer at t' top o' it, as t' tube is designed t' handle t' longer E9s as well. Avast! I set up me ¼ inch 6-foot rod on a very parched baseball field. With t' motor in place I put in "dog barf" as t' waddin' and loaded t' 24-inch Mylar parachute after fluffin' it. Put in an igniter and loaded it on t' pad. Boost was great (fig 12)! Slow and majestic. Ya scallywag! Three seconds be just right on t' delay and t' chute deployed softly and t' rocket came back very nicely. Begad! Altitude be about 400 feet. Ahoy! Avast, me proud beauty! You can see from figure 13 that t' rocket be angled back at about 25 degrees from vertical. Begad! Well, me bucko, blow me down! It was at landin' that catastrophe struck. T' angle o' attack caused a single pod t' strike t' ground first at about a 25 degree angle. Begad! T' paper tube that holds t' sprin' in place burst apart at one o' t' spiral seams, arrr, pushin' t' pod towards t' engine. Ya scallywag! This caused t' two remainin' pods t' strike t' ground with a force from t' inside out (which it isn’t designed t' withstand) shearin' them off. In Figure 14 you can see damage done t' t' rocket. Avast! Lookin' back at Figure 13, shiver me timbers, me bucko, I think that t' parachute never really opened up t' way it should have (shroud lines too short or needs a bigger chute?) and t' rocket came in a little hot. Begad! Add t' hard landin' surface and t' angle o' attack t' that. Aye aye! Arrr! Back at t' house I rebuilt t' Vega and used epoxy clay around all o' t' pod contact areas. This reinforced t' whole fin while sacrificin' only a modest amount o' weight. Blimey! Avast! Returnin' t' t' field a couple o' weeks later with no wind, I launched right away with a F21. Avast! Avast, matey, me proud beauty! What a scream o' a flight! Backed off t' an E18 and still was a magnificent flight.
Con's: Don't fly this in any wind. Avast, me proud beauty! If it comes in at an angle, it lands hard.
Pro's: Stable in flight. Well, me bucko, blow me down! Looks awesome landin' on t' sprin' loaded pods (in no wind).
Flight Rating: 3 out o' 5
Summary:
I feel that I purchased a good kit. Blimey! Blimey! Begad! Blimey! It had some shortcomings with t' shock cord attachment method and t' mylar parachute. Blimey! Blimey! Arrr! Blimey! For those flyin' in even modest winds I would say t' bump up t' parachute size and strengthen t' fin pod filets with epoxy clay instead. Ya scallywag! Blimey! Now havin' said this I can report that QModelin' has already taken care o' t' shock cord and parachute issues and has even gone so far as t' add a Nomex® heat shield t' t' basic kit offering. Avast! Aye aye! With these improvements I believe that this is now a GREAT kit.

Brief: This kit is a beautiful upscale and upgrade to the Estes classic Starship Vega. Magnificently engineered and loaded with top-quality components and features, this rocket would be a great addition to any BAR's fleet. From what I can tell, upgrades to the original design include nose cones on the wing pods/landing gear, a fully functional set of shock absorbers in the landing gear, ...
( Contributed - by Darren J Longhorn) Brief: The MRS-Vega is part of Q Modeling's Mega Retro Series. The series comprises upscale semi-clones of some classic designs, that also includes the Mars Snooper, NikeX & WACC. I say semi-clones, because the kits have been rescaled and designed from scratch using new parts and the latest techniques. The Vega is described as an upscale of ...
