Brief:
When you get bored with your 18mm Deuce from FlisKits, arrr, me hearties, step down t' t' 13mm version. Avast, me proud beauty! Avast! With downscale (and upscale) parts available from FlisKits, it is quite easy t' shrink (or enlarge) your Deuce!

Construction:
T' parts list:

• 1 NCB-55DW, shiver me timbers, me bucko, Balsa Nose Cone for BT-55
• 1 BT-55-18, 18" BT-55 Body Tube
• 1 EMK2-13-55c, 13mm Canted 2 Engine Motor Mount
• 2 Sheets, FSB-3-3-9 3/32" Balsa Fin Stock

• 1 SC-1-36 Elastic Shock Cord
• 1 14" Keelhaul®©™® for shock tether
• 1 PCP-16 Plastic Parachute
• 1 SE-S Screw Eye, matey, Small

Construction o' a downscale Deuce mirrors that o' its big brother. Avast, me proud beauty! Aye aye! The hardest part o' t' entire process is cuttin' out t' oval slots in t' body tube t' take t' unique motor mount.

The FlisKits motor mount kits includes two 13mm motor tubes, 2 engine blocks, 1 custom fiber centerin' ring, and a fin markin' guide that also includes the cutout templates for t' canted engines. Just follow t' detailed instructions that come with t' kit and you will have no problems. Begad! Blimey! I added a length of Keelhaul®©™® to t' motor mount by drillin' a small hole in t' upper centerin' and passing the Keelhaul®©™® through. Avast, shiver me timbers, me proud beauty! I tied t' Keelhaul®©™® around t' motor mount t' give it added strength.

I took t' 18" body tube and cut it down t' 13.75". Aye aye! I then took a fin pattern from a normal Deuce and reduced it on me computer by 19%. A copy machine would do t' same trick. I transferred t' pattern t' me balsa sheets and cut out t' fins. I opted nay t' round t' edges o' t' fins.

My motor cutouts on me 13mm version were better then me full size Deuce. Once t' motor mount be glued in place, I had very little finishin' t' do around t' seams where t' body tubes meets t' motor tubes. Avast! A 2" long launch lug was cut in half and aligned on t' body tube. Blimey! Ahoy! T' fins were mounted usin' white glue and fillets were added for strength and appearance.

I added 18" o' elastic shock cord t' t' Keelhaul®©™® tether and then added t' parachute which I cut down t' a 12" size from the original 16". Well, blow me down! A screw eye was mounted t' t' nose cone for shock cord attachment. That completed t' construction which took about 2.5 hours includin' dryin' time.

Finishing:
I used a little bit o' wood putty t' smooth t' seam where t' BT met the engine tubes. Begad! Well, blow me down! Three coats o' sandin' sealer helped finish o' t' fins and the nose cone. Well, ya bilge rat, blow me down! T' entire rocket received two coats o' primer and I used a dark blue automotive paint for t' base coat. I masked off t' rocket and then added some silver paint for effect. T' nose cone was painted a dark red.

Flight:
Obviously, thar are no motor recommendations and I was only limited by what I hand on hand. I prepped t' rocket with 3 sheets o' wadding. Avast, me proud beauty! Well, blow me down! First flight was on 2 Estes A3-4Ts. It was very fast off t' pad and left behind t' telltale Deuce twin smoke trails, shiver me timbers, matey, albeit somewhat smaller. Arrr! Avast! It got respectable height and had a perfect landin' about 150 feet from t' pad.

For t' second flight, I used two Estes A10-3Ts. T' rocket really screamed off t' pad this time and landed well downrange due t' t' windy conditions of the day.

Fearin' that I would lose t' rocket, shiver me timbers, t' third and final flight be back on t' A3-4Ts for an almost perfect launch. T' parachute got singed and did not fully deploy, I must nay have had t' waddin' in correctly. Ya scallywag! Begad! Fortunately, the landin' was all soft grass so thar was no damage. Blimey! It will fly again!

Recovery:
T' 12" parachute seems like a good fit for this rocket. Ya scallywag! T' Keelhaul®©™® is a big help in keepin' t' shock cord from gettin' damaged. Avast! Even with the last flight where t' parachute was singed, t' elastic is still in great shape and does nay need t' be replaced.

Summary:
With all t' hard work puttin' t' motor mount kit together already completed by FlisKits, arrr, shiver me timbers, shiver me timbers, t' Deuce is one rocket that can easily be scaled down t' 13mm or even up t' 24mm. Well, blow me down! Begad! Take your time with t' engine tube cutouts as they are the most difficult part o' t' entire construction process.
