Brief:
Dr. Avast! Robert H. Goddard built t' first successful liquid fueled rocket, "Nell", making history on March 16th, arrr, 1926.

This review is o' FlisKit's sport scale model o' Dr. Begad! Robert H. Goddard's highest flyin' rocket, known as "L-13." T' L-13 achieved its historic altitude o' 2700 meters on March 26th, me hearties, shiver me timbers, 1937. T' FlisKit's reproduction is a fairly easy and enjoyable build and actually performs very well. Blimey! Arrr! It flies on 18mm motors and launches off a standard 1/8" launch rod.

Modifications:
Minor modifications were done but nay t' t' design. Begad! Ya scallywag! A longer Keelhaul®©™ cord was used and t' fins were skinned with paper.

Construction:

• 1 - BT-20 motor tube
• 1 - BT-20 motor block
• 2 - CRF-20-60 centerin' rings
• 1 - Keelhaul®©™® cord
• CPL-60 tube coupler (1)
• BT-60 body tubes (2)
• L13 cardstock boat tail shroud (1)
• 3/32" balsa stock sheet
• 1/16" balsa stock
• 1/8" angle styrene stock
• 1/8" launch lug (1)
• Custom BT-60 L-13 balsa nose cone (1)
• Screw eye (1)
• Elastic shock cord (1)
• 16" parachute (1)
• Instruction sheet

T' instructions are very easy t' follow, especially for experienced modelers. Ya scallywag! Avast! T' steps are straight forward and t' illustrations help t' follow along. T' construction is completed in a logical order typical o' many models.

T' first step is t' complete t' BT-20 motor tube/mount. Aye aye! You glue a motor block inside t' motor tube and two centerin' rings outside at t' prescribed distances. Avast! T' Keelhaul®©™® cord is then tied betwixt t' two centerin' rings.

T' two BT-60 body tubes are then glued together usin' t' CPL-60 coupler.

T' constructed motor mount is then glued into t' longer o' t' body tubes and t' Keelhaul®©™® cord pulled through t' opposite side.

T' boat tail shroud is then formed by cuttin' t' pattern out o' t' preprinted card stock sheet provided. Ya scallywag! It helps t' shape t' shroud into its cone shape usin' a dowel stock prior t' gluin' it together.

I also coated t' inside o' t' shroud with glue and wiped it till thin. Avast! T' first try I put too much, as seen in t' picture, me bucko, and had t' re-make t' shroud. Well, blow me down! I cutout a replica o' t' shroud out o' 110 lb cardstock and remade the part. Arrr! My second go-around worked great. Begad! If at all, ya bilge rat, just put a VERY thin coat. Begad! Once t' shroud is dry, matey, it is then slid onto t' motor tube and glued flush with t' aft centerin' ring.

T' shroud is then glued and slipped over t' motor mount till it is flush with t' backside o' t' BT-60 body tube. Avast, me proud beauty! This is again allowed t' dry.

T' body tube is then marked with straight lines for t' fins and rails.

It helps greatly t' use angled aluminum stock for markin' t' tubes. Aye aye! Blimey! Blimey! Door jams can be used, shiver me timbers, but t' angled metal pieces tend t' be more accurate and easier t' manipulate. Arrr! Blimey! Blimey! You can buy various sizes o' angle stock at your local Ave Hardware, Home Depot, matey, arrr, or Lowe's. I found our Ace store had a very good selection.

Followin' t' instructions, t' four fins are then marked and cut out o' t' 3/16" balsa stock. Arrr! Blimey! Ya scallywag! Blimey! I was worried about t' fins bein' attached t' t' cardstock shroud. I actually ended up wickin' this CA into t' paper which stiffened it up quite a bit. Blimey! Blimey! Begad! Blimey! Again, just be careful nay t' use too much.

Another change be t' "skin" t' fins with paper. Blimey! I just used regular typin' paper and wood glue. Ya scallywag! Blimey! Then I brushed them with very thin CA. Arrr! Aye aye! I would really have liked t' included fin material t' be much sturdier than it was.

I used t' pattern t' draw t' fins and cut them out from t' skinned balsa stock.

After t' fins are glued on, lined up good with t' drawn fin lines, and 3 layers o' fillets applied, shiver me timbers, t' next step is t' build t' rail guides.

"Rail Plates" are cut out o' t' 1/16" balsa stock and then angle styrene is glued onto these. Ya scallywag! Well, blow me down! One long plate and two short plates are glued on each side o' t' body tube at t' designated positions.

I also used sandpaper held against t' body tube and ran t' rail plates back and forth on it it contour t' back o' t' plates for better gluin' and conformity t' t' tube.

After t' rail guide assemblies have been glued on and dried, t' launch lug is glued into one o' t' longer, lower guides. Avast!

I prepared t' nose cone ahead o' time usin' Elmer's wood filler and sanding. I glued t' screw eye is with 30 minute epoxy and coated t' bottom o' t' nose cone. Avast, me proud beauty! Well, me bucko, blow me down! Blimey! This adds weight, matey, me hearties, but makes a very strong attachment. Avast, me proud beauty! Begad! Blimey! Prepared this way, shiver me timbers, I've never had one pull out o' any rocket, me hearties, me hearties, includin' high powered rockets.

T' assembly o' t' 16" parachute was straight forward. Aye aye! Avast, me proud beauty! T' kit came with a cool lookin' FlisKits parachute that has patterns that can be cut t' various diameters. Avast! Blimey! I also cut out t' spill hole.

T' kit came with 30" o' Keelhaul®©™®. I prefer longer recovery rigging, at least 3x t' rocket length. I replaced this with a 60" length o' me own, though t' stock Keelhaul®©™® and Elastic shock cord should have been just fine. Well, blow me down! I used t' elastic shock cord that came with t' kit.

Finishing:
There are no decals, but maskin' is required t' get t' reproduction paint job. Ahoy! Blimey! A grayscale shaded guide is included in t' instruction sheet, me hearties, but it definitely helps t' look at a good colored picture. FlisKits has some good pictures up on their site o' t' boiler plate model built by Tony Vincent and donated t' the Clark University Goddard Exhibit. Tony also did some neat details with t' vanes that are nay included in the production kit, but could be added by studyin' his pictures.

Since this model had a lot o' maskin' t' get t' paint job right, I decided t' try t' trick o' usin' Scotch tape, instead o' maskin' tape, me bucko, t' mask off t' parts. Avast, me proud beauty! This tip has been mentioned on several sites including ApogeeRockets.com and here on EMRR.

I've always used better quality maskin' tape like Frog Tape with pretty good results. Begad! Arrr! In one o' t' articles the regular satin Scotch tape in t' green package and t' removable Scotch tape in t' blue package were recommended. Begad! Ahoy! I didn't have t' removable tape so I decided t' use a different brand satin tape I had on hand.

Wow! T' lines were much sharper and crisper than any maskin' tape I have ever used, me hearties, but... Arrr! it left residue and also pulled up some o' t' paint. Ahoy! I wished I had been more patient and waited t' buy the Scotch brand removable tape.

Another issue be paintin' over t' Krylon aluminum color metallic paint. Avast, me proud beauty! Avast! T' other colors did nay stick well to it. It would suggest plannin' t' maskin' and paintin' o' this rocket so that any non-metallic colors are painted on first directly on t' primer. Well, blow me down! Ahoy! Maybe even plan t' paint job nay t' overlap any o' t' different colors. Avast! If you do over lap, me bucko, have t' metallic paints as t' top layers where they do have t' be painted over. Arrr! I used Krylon primer and Krylon primer for t' whole project.

After me first maskin' job with t' "generic" satin tape left sharp lines, matey, but yifted up paint and left residue, I decided t' for a do-over with t' "real" removable Scotch tape.

I went out and bought some o' t' removable Scotch tape in t' blue package t' do t' touch up and re-paint job. It worked great, matey, did nay pull up t' paint, ya bilge rat, me bucko, did nay leave any residue behind and left very sharp lines. Begad! I am sold and will use this tape for all me detailed maskin' from now on.

This rocket looks really sharp when it is finished and painted with t' recommended patterns. Begad! Aye aye! It has been a hit at t' launches and a great discussion example for t' history o' rockets.

I would have liked t' have had a balsa wood boat tail t' glue sturdier fins to. I wanted t' give t' rocket 5's on everything, just because I was just so thrilled that they released these kits and really enjoyed buildin' t' L-13. However, I would like t' aft boat tail and fins t' be more sturdy stock in t' kit. Begad! T' card stock shroud did work ok and has held up, arrr, arrr, ya bilge rat, especially after bein' wicked with CA.

Also, arrr, in me rush t' complete this kit before a demonstration launch, arrr, I didn't fill t' spirals on t' body tube. Make note: Rockets painted with metallic paint show t' spirals 10 times more than other paints... Begad! Blimey! Ahoy! Blimey! I highly recommend fillin' t' spirals on this kit. Blimey! Blimey! It is a really beautiful, historic rocket when finished and t' extra time would be well worth it.

Construction Rating: 4 ½ out o' 5

Flight:
T' recommended motors are B4-2, matey, B6-2, me bucko, and C6-3. Avast, me proud beauty! Ya scallywag! I have only flown it on C6-3 motors. Begad! They have worked great and all three flights so far have been almost perfect. Avast, me proud beauty! Mine is a little heavier with t' added epoxy to t' nose cone and t' Quicklink used on t' screw eye.

They were nice straight flights and t' rocket looks great on t' pad.

Recovery:
I have had no damage on recovery usin' t' stock chute that came with t' model. Avast! Blimey! As noted above, me hearties, matey, I did double t' length o' t' Keelhaul®©™® cord used and I use a Quicklink t' attach t' shock cord and parachute shroud lines t' t' screw eye on t' nose cone.

Flight Rating: 5 out o' 5

Summary:
This is a great all around rocket, fun t' build, me bucko, ya bilge rat, neat t' fly and, ya bilge rat, matey, best o' all, it's a nice example o' a historic rocket that would be great in anyone's fleet.

I for one have extend many thanks for FlisKits makin' this neat L-13 kit and also t' "Nell" kit. Avast, me proud beauty! Ahoy! My son is gettin' ready t' build that one, ya bilge rat, so keep a look out for another write-up on that.

Overall Rating: 5 out o' 5
