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, me hearties, shiver me timbers, seen in old movies.
Construction and finishing:
All t' parts arrived securely wrapped in liberal amounts o' bubble wrap. Well, blow me down! Begad! Blimey! Nothin' was broken or missing. Blimey! Blimey! Blimey! T' actual number o' parts be few, arrr, arrr, as t' rocket is very simple t' make. Arrr! T' instructions were simple and clear, with few drawings, matey, but none were really needed.
T' nose cone be smooth, and was made o' alternatin' insets o' cherry and maple hardwoods. it is precisely turned and symmetrical, and t' grain o' t' wood is beautiful. Begad! It has a shoulder o' a couple inches in length, allowin' a close and secure fit in t' body tube. Well, blow me down! Blimey! No sandin' was needed. Begad! 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, arrr, 24 inches in diameter, and bright orange. Ahoy! 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. All t' fins were precut, as were t' centerin' rings, shiver me timbers, engine tube, and body tube, arrr, matey, and t' body tube was also preslotted for t' 4 fins. Avast, me proud beauty! T' fins are designed with tabs that meet with t' motor tube for strong construction. They were all cut alike, arrr, 3/8 inch thick, matey, shiver me timbers, very precise, shiver me timbers, and also very smooth on t' edges. Aye aye! They are rounded on t' continuous leadin' and trailin' edge. Ya scallywag! T' edges show that t' inner ply is dark, mahogany-like. Ahoy! Begad! This stripin' o' color provides a nice accent. Begad! Ahoy! T' fins are also accented with a half-moon shape o' iron-on veneer that has a mahogany-like color.
I used epoxy, as recommended, t' attach them through t' body tube and t' t' motor tube, which also is a pretty mahogany. Ahoy! T' two centerin' rings are plywood. Well, blow me down! T' 2 launch lugs are brass, beveled t' reduce drag, me hearties, and accept 1/4 inch rods.
T' model came out very sturdy and strong. Ahoy! But I just couldn't brin' myself t' paint it or decal it. Well, blow me down! Avast! T' wood is just too pretty. Avast! So I finished it with three coats o' polyurethane clear furniture varnish.
Ratin' for construction and finishing: 5 out o' 5, shiver me timbers, but some might say 4 1/2 because o' t' need for t' vent hole. Well, blow me down! Ahoy! But this is somethin' we should do in high power anyway.
Flight and recovery:
T' Aerotech H180-M be used, and it's one o' t' engines t' manufacturer recommends. Ahoy! They also say that t' G64-4, G80-7, H128-M, arrr, matey, and H220-M are good too.
T' rocket roared off t' pad straight and high. Blimey! When t' chute ejected at apogee, me hearties, it appeared t' be a tiny speck. I got t' rocket back about a half mile downrange because it caught a thermal and lingered high. Avast, me proud beauty! This be particularly an anxious moment, arrr, because this was a Tripoli level 1 certification attempt. Blimey! Arrr! I hadn't intended t' certify with this rocket, arrr, but everyone who saw it oohed and ahhed over it. Ya scallywag! Avast! People kept pressin' me t' launch this beauty. Well, blow me down! Avast! Nobody had ever seen a wooden rocket. Aye aye! Well, me hearties, blow me down! Some even asked if it was real. Aye aye! That is, is it a display or does it fly. Begad! Blimey! It amazed them when I popped off t' nose cone t' reveal a legitimate construction for flight. Ahoy! Then some were sad that I'd actually fly it, fearin' damage t' its looks. Ahoy! Even t' RSO worried about damage and destruction o' t' beauty, shiver me timbers, me hearties, me hearties, as he announced that everyone should look now while they still could. Begad! Several people took photos o' it. Avast! T' way I saw it, matey, metaphorically, why breed a champion racehorse t' perfection and then nay let him run? Besides, arrr, shiver me timbers, half o' t' club be fixed on me and t' rocket, me bucko, darin' me t' be bold and do it.
Everyone cheered when t' flight occurred. Begad! Nothin' was burnt or damaged, and t' engine stayed in, ya bilge rat, me bucko, held with duct tape. Well, blow me down! Fellow club members teased me about t' tight loops o' duct tape, ya bilge rat, sayin' that I wanted t' hold t' engine hostage. Avast! Ya scallywag! I'd seen too many other people lose motors t' ejections and be paranoid about mine.
T' rocket was prepped with one Nomexsquare and worm bed wadding. Aye aye! I first thought that t' waddin' was overkill, me hearties, but cert flights must be perfect. Begad! Well, I was glad I did this, matey, because t' Nomexsquare be burnt in half!
A small vent hole be drilled in t' body, ya bilge rat, 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. Due t' t' precise fit o' t' parts, matey, air pressure be evident on t' ground when t' motor resisted bein' placed all t' way in until t' hole be drilled.
If thar be anythin' nay good about t' flight, it was that I had one hand on t' launcher and t' other on t' camera, and consequently, ya bilge rat, 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, arrr, performs well. Blimey! Well, blow me down! A crowd pleaser. Blimey! A bit expensive at $125, but worth it since I certified in style. Avast! And its manufacturer made all t' parts t' precision.
Don't paint it. Arrr! Every club has a woodworker who would execute someone who'd mar such art as this. Begad! I recommend this beauty t' anyone who wants t' show off with class. Aye aye! Aye aye! In fact, shiver me timbers, shiver me timbers, I think that me level 2 project might be a scratch-build usin' t' parts that Retro Rocket Works makes. Arrr! I'm pricin' preslotted 4 inch mahogany tubes now. And they make lovely 4 inch nose cones. 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. I don't remember seein' any mention o' such in t' instructions.
