Brief description:
Single staged, 29mm motor rocket in all wood construction and retro lookin' design, arrr, arrr, much like t' stout sci fi rocketships with huge swept back fins, arrr, seen in old movies.
Construction and finishing:
All t' parts arrived securely wrapped in liberal amounts o' bubble wrap. Avast! Nothin' was broken or missing. Ya scallywag! T' actual number o' parts be few, arrr, as t' rocket is very simple t' make. Arrr! T' instructions were simple and clear, with few drawings, but none were really needed.
T' nose cone be smooth, arrr, me hearties, me bucko, and was made o' alternatin' insets o' cherry and maple hardwoods. Arrr! it is precisely turned and symmetrical, and t' grain o' t' wood is beautiful. Blimey! It has a shoulder o' a couple inches in length, allowin' a close and secure fit in t' body tube. Aye aye! No sandin' be needed. Well, blow me down! 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, 24 inches in diameter, arrr, arrr, matey, and bright orange. Avast! 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, ya bilge rat, me hearties, me bucko, with swirly grain patterns. Avast! All t' fins were precut, as were t' centerin' rings, engine tube, shiver me timbers, arrr, and body tube, matey, and t' body tube was also preslotted for t' 4 fins. Blimey! T' fins are designed with tabs that meet with t' motor tube for strong construction. Avast! They were all cut alike, ya bilge rat, 3/8 inch thick, very precise, matey, shiver me timbers, and also very smooth on t' edges. They are rounded on t' continuous leadin' and trailin' edge. Ahoy! T' edges show that t' inner ply is dark, mahogany-like. Begad! This stripin' o' color provides a nice accent. Avast! T' fins are also accented with a half-moon shape o' iron-on veneer that has a mahogany-like color.
I used epoxy, matey, as recommended, t' attach them through t' body tube and t' t' motor tube, which also is a pretty mahogany. Begad! T' two centerin' rings are plywood. Begad! T' 2 launch lugs are brass, me bucko, beveled t' reduce drag, and accept 1/4 inch rods.
T' model came out very sturdy and strong. But I just couldn't brin' myself t' paint it or decal it. T' wood is just too pretty. Aye aye! 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. Avast! But this is somethin' we should do in high power anyway.
Flight and recovery:
T' Aerotech H180-M was used, and it's one o' t' engines t' manufacturer recommends. Well, blow me down! They also say that t' G64-4, G80-7, me bucko, H128-M, and H220-M are good too.
T' rocket roared off t' pad straight and high. Well, blow me down! Blimey! When t' chute ejected at apogee, it appeared t' be a tiny speck. Arrr! Blimey! I got t' rocket back about a half mile downrange because it caught a thermal and lingered high. This be particularly an anxious moment, because this be a Tripoli level 1 certification attempt. I hadn't intended t' certify with this rocket, me hearties, matey, me hearties, but everyone who saw it oohed and ahhed over it. Ya scallywag! Blimey! People kept pressin' me t' launch this beauty. Blimey! Blimey! Nobody had ever seen a wooden rocket. Some even asked if it be real. That is, is it a display or does it fly. Blimey! Blimey! Ahoy! Blimey! It amazed them when I popped off t' nose cone t' reveal a legitimate construction for flight. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! Then some were sad that I'd actually fly it, shiver me timbers, fearin' damage t' its looks. Aye aye! Blimey! Even t' RSO worried about damage and destruction o' t' beauty, shiver me timbers, arrr, me bucko, as he announced that everyone should look now while they still could. Aye aye! Blimey! Well, blow me down! Blimey! Several people took photos o' it. T' way I saw it, metaphorically, 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, darin' me t' be bold and do it.
Everyone cheered when t' flight occurred. Nothin' be burnt or damaged, and t' engine stayed in, matey, held with duct tape. Avast! Avast, me proud beauty! Fellow club members teased me about t' tight loops o' duct tape, sayin' that I wanted t' hold t' engine hostage. Avast, me proud beauty! I'd seen too many other people lose motors t' ejections and was paranoid about mine.
T' rocket was prepped with one Nomexsquare and worm bed wadding. I first thought that t' waddin' be overkill, shiver me timbers, but cert flights must be perfect. Well, me hearties, I be glad I did this, because t' Nomexsquare was burnt in half!
A small vent hole be drilled in t' body, matey, 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, air pressure was evident on t' ground when t' motor resisted bein' placed all t' way in until t' hole was 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, 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, ya bilge rat, performs well. A crowd pleaser. A bit expensive at $125, but worth it since I certified in style. Begad! Begad! And its manufacturer made all t' parts t' precision.
Don't paint it. Avast, me proud beauty! Avast, me proud beauty! Every club has a woodworker who would execute someone who'd mar such art as this. Blimey! Begad! I recommend this beauty t' anyone who wants t' show off with class. In fact, matey, I think that me level 2 project might be a scratch-build usin' t' parts that Retro Rocket Works makes. Arrr! Avast, me proud beauty! I'm pricin' preslotted 4 inch mahogany tubes now. Aye aye! 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 be very important in preventin' premature separation o' t' nose cone. Ahoy! Begad! I don't remember seein' any mention o' such in t' instructions.
