Brief:
This Goony version o' t' Fireball XL5 sci-fi model is based on t' Estes SpaceShipOne kit. Blimey! Avast, me proud beauty! This kit, which I buy at Michael's crafts with 50% off coupons, me hearties, is now me favorite kit t' bash. Begad! Well, blow me down!

Modifications:
T' modifications included replacin' t' stock fins, matey, replacin' t' stock recovery system, shiver me timbers, arrr, and modifyin' t' nose cone. Avast, me proud beauty! Aye aye! T' motor mount is stock.

Construction:
Parts list:

• Estes SpaceShipOne kit
• 3/16" fin stock
• lead shot
• small eyebolt
• steel fishin' leader
• extra elastic chock cord

All o' t' fins were roughed-out on paper until they looked right. Well, matey, blow me down! T' side fins were made from two pieces of 3/16" stock each. Begad! Begad! T' two pieces touch at their leadin' edge and are separated by a strip o' balsa in t' rear. T' leadin' edge be then sanded t' a smooth point. T' side fins were cut from 3/16" stock. Ahoy! T' small fins on the cone are t' small fin extensions from t' SS1 kit. Blimey! T' kit provided two and I cut t' others from t' unused fin stock. Avast! T' balsa-plastic joints were attached with thick CA and wood glue be used on t' wood-wood joints.

I attached a steel fishin' leader t' t' top centerin' rin' and t' stock elastic cord t' that. Avast! Blimey! I had planned to use two chutes due t' t' expected weight o' t' nose, so a separate shock cord was provided for it. Ya scallywag! Blimey! Ya scallywag! Blimey! I knew I'd need a lot o' nose weight so I attached t' cord t' an eyebolt that is embedded in a slurry o' lead shot and Gorilla Glue. That way, matey, t' weight is securely attached t' t' recovery system. Blimey! Blimey! O' course, t' nose weight was t' last step. The bottom o' t' cone be removed t' allow access for t' nose weight installation and t' provide a tad more room for the 'chute if needed.

As I noted earlier, t' motor mount be t' stock 18mm. Blimey! I was lucky t' have t' new RockSim 9 program with its PODS feature. Begad! This allowed me t' simulate t' actual design configuration. I set t' nose weight based on this simulation model.

With t' unloaded weight sittin' at about 5oz, t' sim indicated a long rod was need for a stable C6 flight. So, early on, I decided t' go for a reload. Ya scallywag! I got an 18mm Hobbyline case and a pack o' D13-10s from ValueRockets.com. Great prices and speedy service!

Finishing:
I did t' normal filling/sanding/primin' drill. Begad! T' base coat is a silver primer for t' X-Metals paint. Aye aye! Avast! I then used brush-on paints for t' red and yellow trim. Avast! Avast, me proud beauty! T' circles are from t' SS1 'decal' set, t' colored band was printed on my ink jet, me bucko, and t' 'goony' letterin' is vinyl from Michael's craft store.

Flight:
T' D13 was easy t' assemble. Begad! Since I was at MDRA, ya bilge rat, arrr, shiver me timbers, I was able t' drill t' delay usin' t' same method specified for the 29mm and larger motors. I filled t' bottom o' t' body with dog barf, me hearties, added several pieces o' wadding, me hearties, and then some more dog barf. Avast, me proud beauty! I decided t' go with one 18" chute, which was attached t' both shock cords.

At t' 11th hour, I realized that I'd used t' stock lug and decided this rocket was too heavy and unproven to fly with that. Begad! I removed at lug and epoxied on a piece o' ¼" compatible launch lug material (e.g. a tube from an AeroTech First Fire igniter).

I set each side fin on a stand-off and hooked up t' Copperhead. Avast! Well, ya bilge rat, blow me down! T' rocket flew great with some spin, which was undoubtedly t' result o' some imperceptible misalignment o' one or more fins. Arrr! After all, shiver me timbers, shiver me timbers, I built it.

Ejection be just a tad late and t' rocket recovered damage-free.

Summary:
I love t' Fireball design and thin' t' Estes SpaceShipOne kit is a great subject for kitbashing. Begad! This model flew nicely and is a proud member o' me Fireball XL5 rocket family.
