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

Construction:
T' parts list:

Construction o' a downscale Deuce mirrors that o' its big brother. Ya scallywag! Arrr! 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, ya bilge rat, 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. Aye aye! I added a length of Keelhaul®©™® to t' motor mount by drillin' a small hole in t' upper centerin' and passing the Keelhaul®©™® through. Blimey! 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". Arrr! Blimey! 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. Ahoy! Blimey! Blimey! Blimey! I transferred t' pattern t' me balsa sheets and cut out t' fins. Avast, me proud beauty! Blimey! Aye aye! Blimey! Blimey! Blimey! 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, me proud beauty! Ya scallywag! A 2" long launch lug be cut in half and aligned on t' body tube. Begad! 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". Begad! Blimey! Ahoy! Blimey! A screw eye be mounted t' t' nose cone for shock cord attachment. Begad! Blimey! 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. Well, blow me down! Three coats o' sandin' sealer helped finish o' t' fins and the nose cone. Begad! 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. Well, blow me down! Avast! T' nose cone was painted a dark red.

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

For t' second flight, me bucko, 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, t' third and final flight was back on t' A3-4Ts for an almost perfect launch. Begad! T' parachute got singed and did not fully deploy, arrr, me hearties, I must nay have had t' waddin' in correctly. Begad! Begad! Fortunately, the landin' be all soft grass so thar was no damage. It will fly again!

Recovery:
T' 12" parachute seems like a good fit for this rocket. Avast! Ahoy! T' Keelhaul®©™® is a big help in keepin' t' shock cord from gettin' damaged. Begad! Arrr! Even with the last flight where t' parachute be singed, me hearties, 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, t' Deuce is one rocket that can easily be scaled down t' 13mm or even up t' 24mm. Avast, me proud beauty! Take your time with t' engine tube cutouts as they are the most difficult part o' t' entire construction process.
