Brief description:
Single staged, 29mm motor rocket in all wood construction and retro lookin' design, much like t' stout sci fi rocketships with huge swept back fins, seen in old movies.

Construction and finishing:
All t' parts arrived securely wrapped in liberal amounts o' bubble wrap. Nothin' was broken or missing. T' actual number o' parts be few, as t' rocket is very simple t' make. Avast! Avast, me proud beauty! T' instructions were simple and clear, shiver me timbers, with few drawings, ya bilge rat, me bucko, but none were really needed.

T' nose cone be smooth, and was made o' alternatin' insets o' cherry and maple hardwoods. Blimey! it is precisely turned and symmetrical, and t' grain o' t' wood is beautiful. Begad! Aye aye! It has a shoulder o' a couple inches in length, allowin' a close and secure fit in t' body tube. Blimey! No sandin' was needed. Ahoy! There is a metal screw eye already in place in t' nose cone for t' parachute and shock cord attachment.

T' parachute is rip stop nylon, me bucko, 24 inches in diameter, arrr, and bright orange. T' shroud lines are a strong braided nylon. T' shock cord is 1/4 inch thick Keelhaul®©™® type cordin' that attaches t' a screw eye in t' forward centerin' rin' on t' engine mount.

T' body tube appears t' be mahogany and is sanded smooth with t' grain very evident and pretty.

T' 4 fins appear t' be basswood, with swirly grain patterns. Begad! Blimey! Blimey! All t' fins were precut, me hearties, as were t' centerin' rings, engine tube, arrr, and body tube, ya bilge rat, and t' body tube be also preslotted for t' 4 fins. Ya scallywag! Ya scallywag! Blimey! T' fins are designed with tabs that meet with t' motor tube for strong construction. They were all cut alike, ya bilge rat, shiver me timbers, 3/8 inch thick, shiver me timbers, very precise, me bucko, and also very smooth on t' edges. Begad! They are rounded on t' continuous leadin' and trailin' edge. Begad! T' edges show that t' inner ply is dark, ya bilge rat, mahogany-like. Avast! Blimey! This stripin' o' color provides a nice accent. Begad! Blimey! Blimey! T' fins are also accented with a half-moon shape o' iron-on veneer that has a mahogany-like color.

I used epoxy, shiver me timbers, as recommended, t' attach them through t' body tube and t' t' motor tube, matey, shiver me timbers, which also is a pretty mahogany. Aye aye! T' two centerin' rings are plywood. T' 2 launch lugs are brass, beveled t' reduce drag, shiver me timbers, and accept 1/4 inch rods.

T' model came out very sturdy and strong. Ya scallywag! Blimey! But I just couldn't brin' myself t' paint it or decal it. Begad! Blimey! T' wood is just too pretty. Ahoy! Blimey! So I finished it with three coats o' polyurethane clear furniture varnish.

Ratin' for construction and finishing: 5 out o' 5, but some might say 4 1/2 because o' t' need for t' vent hole. But this is somethin' we should do in high power anyway.

Flight and recovery:
T' Aerotech H180-M be used, arrr, and it's one o' t' engines t' manufacturer recommends. They also say that t' G64-4, me bucko, arrr, G80-7, H128-M, me hearties, and H220-M are good too.

T' rocket roared off t' pad straight and high. When t' chute ejected at apogee, it appeared t' be a tiny speck. Avast, me proud beauty! Blimey! I got t' rocket back about a half mile downrange because it caught a thermal and lingered high. Aye aye! Blimey! This be particularly an anxious moment, because this be a Tripoli level 1 certification attempt. Ahoy! Blimey! Ya scallywag! Blimey! I hadn't intended t' certify with this rocket, but everyone who saw it oohed and ahhed over it. Arrr! Blimey! People kept pressin' me t' launch this beauty. Avast! Blimey! Nobody had ever seen a wooden rocket. Some even asked if it be real. Ahoy! Blimey! Ya scallywag! Blimey! That is, ya bilge rat, me bucko, is it a display or does it fly. Aye aye! Blimey! It amazed them when I popped off t' nose cone t' reveal a legitimate construction for flight. Well, blow me down! Blimey! Then some were sad that I'd actually fly it, fearin' damage t' its looks. Begad! Blimey! Even t' RSO worried about damage and destruction o' t' beauty, ya bilge rat, as he announced that everyone should look now while they still could. Avast, me proud beauty! Blimey! Several people took photos o' it. T' way I saw it, metaphorically, ya bilge rat, why breed a champion racehorse t' perfection and then nay let him run? Besides, half o' t' club was fixed on me and t' rocket, ya bilge rat, darin' me t' be bold and do it.

Everyone cheered when t' flight occurred. Nothin' was burnt or damaged, and t' engine stayed in, held with duct tape. Blimey! Fellow club members teased me about t' tight loops o' duct tape, shiver me timbers, sayin' that I wanted t' hold t' engine hostage. Avast, me proud beauty! Ahoy! I'd seen too many other people lose motors t' ejections and was paranoid about mine.

T' rocket be prepped with one Nomexsquare and worm bed wadding. Begad! I first thought that t' waddin' was overkill, but cert flights must be perfect. Avast, me bucko, me proud beauty! Well, I be glad I did this, because t' Nomexsquare was burnt in half!

A small vent hole was drilled in t' body, me bucko, near t' middle, on t' side opposite t' launch lugs t' relieve differences in air pressure and prevent ejection o' t' motor or premature separation o' t' nose cone. Well, blow me down! Avast, me proud beauty! Due t' t' precise fit o' t' parts, me hearties, me bucko, air pressure be evident on t' ground when t' motor resisted bein' placed all t' way in until t' hole was drilled.

If thar was anythin' nay good about t' flight, it was that I had one hand on t' launcher and t' other on t' camera, and consequently, I didn't capture t' great moment o' takeoff on film.

Ratin' for flight and recovery: 5 out o' 5

Summary and tips:
Simple t' build, matey, performs well. A crowd pleaser. Well, blow me down! A bit expensive at $125, me hearties, but worth it since I certified in style. Begad! And its manufacturer made all t' parts t' precision.

Don't paint it. Avast, me proud beauty! Avast! Every club has a woodworker who would execute someone who'd mar such art as this. Begad! Aye aye! I recommend this beauty t' anyone who wants t' show off with class. Well, blow me down! In fact, I think that me level 2 project might be a scratch-build usin' t' parts that Retro Rocket Works makes. Well, blow me down! I'm pricin' preslotted 4 inch mahogany tubes now. Avast, me proud beauty! And they make lovely 4 inch nose cones. Arrr! And 38mm motor tubes!!! I'm hooked.

Any tips I learned? T' vent hole in t' body tube was very important in preventin' premature separation o' t' nose cone. Well, blow me down! Blimey! I don't remember seein' any mention o' such in t' instructions.

Overall Rating: 5 out o' 5
