Brief:
This is a plastic model conversion o' t' Revell 1/48 scale model o' t' F-18 Hornet Blue Angel. Aye aye! This was t' first plastic model conversion I had ever attempted and would nay have done so if it were nay for t' EMRR 2006 Challenge. Begad! It was a lot o' fun puttin' this rocket together.
Modifications:
T' begin construction, shiver me timbers, I glued t' engine blocks inside t' motor mount tubes usin' a spent engine casin' and allowin' 1/8" o' t' motor t' stick out t' back. Ahoy! After this dried, arrr, me bucko, me bucko, I took t' bottom half o' t' plastic body and laid these two tubes inside o' it where they pressed up against t' plastic stop in t' middle o' t' body. They hung out slightly from t' two engine holes in t' back. Aye aye! Avast, arrr, me proud beauty! I aligned these until I thought they were in t' straightest and best lookin' place and then used 15 minute epoxy t' hold them in that place. Well, me bucko, blow me down! I did this by just pourin' t' epoxy around t' motor tubes at both ends. I allowed some o' t' epoxy t' flow down inside t' forward ends o' t' tubes t' better hold them in place. Begad! Just be sure t' have room in t' tubes for t' ejection charges t' escape. I then cut an Estes style shock cord mount out o' a piece o' paper and used epoxy t' attach this just aft o' t' forward landin' gear well. Begad! Arrr! T' small gap betwixt this landin' gear area and t' inner wall was a great place for t' shock cord t' come through and it gave it added strength.
While this was settin' up on t' lower half, shiver me timbers, I next worked on t' upper half o' t' body. Begad! Aye aye! T' only really work that had t' be done was t' placement o' t' cockpit windows so t' ejection charges could nay leak out through t' hole in t' upper body section. Arrr! First, t' small U-shaped plastic piece be epoxied in place around t' area where t' cockpit chair would have been placed. Begad! Begad! Next, arrr, me hearties, t' two clear windows were epoxied on over this and epoxy was placed betwixt them t' be sure t' seal all gaps.
After these two sections were set, ya bilge rat, t' aft horizontal fins were put it place. Well, blow me down! There is a plastic bar connectin' t' two which must be cut. Ya scallywag! I left a small portion o' this bar on both fins so these could be placed through t' holes in t' sides o' t' body and epoxied t' t' motor mount tubes. I then placed epoxy on t' bottom edge o' this fin and attached it t' t' bottom half o' t' plastic body tube.
Next t' two halves are put together. Ahoy! I covered t' seam in epoxy all t' way around and applied liberal amounts o' in on t' win' areas. I be afraid that t' two halves may come apart durin' flight or due t' t' ejection charge. Begad! I then used strong clamps on each win' t' hold it all together flush.
Once that was dry, me hearties, I used epoxy t' attach t' vertical fins. Avast! Ahoy! I just placed t' epoxy on t' bottom edge and on t' tabs and slid them into t' slot.
T' trickiest part be gettin' t' nose cone t' work. Begad! I wanted t' use t' one that came in t' plastic kit but it has no shoulder. Avast, me proud beauty! Avast! I decided t' make one usin' two small pieces o' balsa wood. Avast! Begad! I epoxied them t' t' inside o' t' nose cone with half o' each piece stickin' out. Avast! Once it dried, me hearties, shiver me timbers, I shaved off pieces o' each one until it finally fit snuggly on t' top o' t' rocket. Begad! I then used another Estes style shock cord mount t' attach t' other end o' t' shock cord, ya bilge rat, and tied a streamer t' t' cord near t' nose cone.
Construction:
These are t' parts I used for this plastic model conversion:
There are 6 fins total on this rocket, t' two main fins which are part o' t' plastic body, arrr, t' two vertical fins on t' rear, and t' two horizontal fins on t' rear. Begad! No centerin' rings were needed for construction. Arrr! T' nose cone and shock cord are attached with epoxy and Estes style shock cord mounts.
Well only 9 o' t' 70+ parts from t' actual plastic kit were used. I thought about puttin' some detailed stuff on it such as t' landin' gear, but I figured that it might crash and all that effort go t' waste anyway so why bother. Begad! I'm sure it would look pretty nice with all t' bells and whistles on it though.
T' motor mount was small for t' size and weight o' this rocket. Begad! Blimey! Avast! Blimey! If I went back and did it again I would have cut out part o' t' back end o' t' plastic casin' and put in a 18mm cluster rather than a 13mm one. Arrr! Blimey! Avast, me proud beauty! Blimey! Also since thar are no centerin' rings for t' tubes, they need t' be aligned perfectly by sight for t' cluster t' work properly.
This is a pretty quick build if you are usin' 5 or 15 minute epoxy and it looks nice. Begad! I chose t' wait until I had test flown it before addin' any decals or fancy things t' it, so for it's flight it was just t' plain blue plastic it came lookin' as. T' clear cockpit does make it look nice though and allows t' recovery system t' be seen as well.
Flight and Recovery:
Well I used two A10-3Ts for this rocket, ya bilge rat, but if I had t' recommend motors, shiver me timbers, these are way too small. Well, blow me down! Blimey! T' motors are friction fit, so I just wrapped a piece o' maskin' tape around t' middle o' both o' them. Avast, me proud beauty! Blimey! This worked fine. Arrr! Blimey! Insert t' two motors and add some waddin' then pack t' streamer and put on t' nose cone. Avast! Blimey! Ahoy! Blimey! I used a clip whip for ignition, but I'm sure twistin' t' ignitor leads together would work just as well.
T' flight never gained any significant altitude. Begad! Both motors lit and it took off straight up t' maybe about 40 feet high. Aye aye! It then flopped back down and crashed. After it had been on t' ground, me hearties, t' ejection charge fired. Arrr! Well, shiver me timbers, blow me down! It landed nay 5 feet from t' pad though. Ahoy! Upon further inspection, matey, t' two plastic halves split at their epoxy joint all t' way down t' rocket on one side. Begad! Avast! I'm nay sure if this is due t' t' crash or t' ejection charge or maybe both.
T' recovery system deployed on t' ground just fine however. Avast! I be slightly worried that t' streamer would get stuck. Begad! I think this rocket would need a small parachute if it could get one out before it hit t' ground.
Summary:
PROs: Quick build, plastic model conversion, shiver me timbers, scale model o' a NAVY fighter, ya bilge rat, and it is a cluster rocket.
CONs: Way underpowered, me hearties, needs buffed up construction t' stay together, and needs larger motor mounts.
I had great fun buildin' and flyin' (or crashing) this rocket. Aye aye! It be a great experience t' try somethin' new which I otherwise would nay have. Begad! I enjoyed it and learned t' pay a bit more attention t' me motor selection on any more scratch built rockets I have in t' future.

Just curious what the final weight of the rocket was without motors. I would have thought 2 A's would have been sufficient power but again that would depend on weight. Nice conversion nonetheless.
