"Futuristic Starship Design"
"Long, shiver me timbers, sleek appearance"
"Highly stable for fantastic flights!"
"Wind cheatin' design for extreme altitudes!"
Those are t' headlines on t' FlisKits Corona. Well, blow me down! Ahoy! T' Corona is a "longneck" rocket with and interesting, me hearties, perhaps one would say, futuristic, fin/ring-fin configuration. Arrr! Aye aye! It has a nice "sleek" appear because t' fins are nay wide, even after bein' surrounded by t' ring-fin.
T' Corona is classified by EMRR as a "longneck" because it has a 0.976" diameter and is 41.0" long, givin' it a 42:1 length t' diameter ratio. Way back when EMRR started t' site and be settin' up keywords, anythin' with a 30:1 and higher ratio be deemed a "longneck".
T' rocket includes two 17" long, arrr, 0.976" diameter, arrr, me bucko, light brown paper body tube for t' main body and a 4 3/16" solid balsa nose cone. T' kits includes much more than enough 1/16" balsa fin stock t' cut out t' fins from and 2.18" long, me bucko, arrr, 1.25" diameter ring-fin. T' motor mount consists o' one 18mm motor tube, a thrust ring, shiver me timbers, arrr, two centerin' rings and a motor hook. Blimey! T' recovery system made up o' a 36" long, arrr, arrr, 1/8" wide, white elastic shock cord, ya bilge rat, a 3-fold paper mount, me hearties, and a plastic parachute that t' builder assembles. Lastly t' kit includes two 1/8" diameter launch lugs.
CONSTRUCTION:
T' instructions are printed on both sides o' a single page o' 8½ x 11" paper (folded in thirds for a nice 6-page instruction set). Ahoy! However, shiver me timbers, this is complemented with a parts and tools needed list on t' back t' t' kit's placard. Also thar be a template page with a preflight checklist. T' instructions include illustrations t' ensure success.
FlisKits calls this a Skill Level 2 kit. Begad! We agree.
T' motor mount is built first. Avast, me proud beauty! Blimey! Blimey! Blimey! It is fairly typical with t' motor hook bein' held in place with maskin' tape. Begad! Blimey! You have t' cut a section out o' t' lower centerin' rin' (cardboard) t' allow for t' motor hook.
T' fins are next. Avast! After cuttin' out t' cardstock templates and tracin' them on t' balsa stock, me bucko, they are cut out usin' a sharp hobby knife. Well, blow me down! Aye aye! There are three upper and three lower sections for t' fins. These are then airfoiled and an upper is glued t' a lower t' make up a single fin. Well, blow me down! This is repeated for all t' fins.
Next, t' body tube is marked usin' a cardstock fin markin' guide. Lines are extended on t' tube. Avast, me proud beauty! Avast! I used t' door jam method.
T' motor mount is then slide into t' lower body tube (the one just marked). Arrr! Avast, me proud beauty! It protrudes by 1/4". Ahoy! This step is important because dependin' on your glue (white or wood) you could get it stuck. Well, blow me down! It has t' be a smooth and quick motion t' get t' motor tube in without issue. Begad! T' instructions are clear on this.
Next, ya bilge rat, t' upper body tube is added usin' a 1" coupler.
Then, t' balsa fins are glued onto t' fin lines. They are aligned with t' bottom o' t' tube. Blimey! T' launch lugs are also glued in place. Begad! Once all dry, matey, t' ring-fin is glued in place.
T' last steps are t' attached t' eye-screw t' t' nose cone, t' elastic shock cord t' t' eye-screw and t' 3-fold paper mount it t' t' inside o' t' upper body tube. Begad! T' parachute is then assemble. Ya scallywag! My only nay here, is that FlisKits didn't indicate which parachute size t' assemble. T' plastic parachute sheet can make up a 16", 12" and 7½" parachute. Arrr! I chose t' 7½" parachute since I anticipate fairly high flights.
FlisKits gives some basic finishin' guidance includin' sealin' t' balsa with 2-3 coats o' sandin' sealer, arrr, then prime t' rocket prior t' painting.
I have been surprised with several days just at 50 degrees F, me hearties, so I have been able t' use me typical multiple coats o' Plastic-Kote Primer and sandin' in-between. Arrr! Then amazingly, shiver me timbers, on t' last day o' November, me hearties, shiver me timbers, it was warm enough t' paint. Ya scallywag! I used Walmart Silver paint on t' whole body. Aye aye! I let that dry for about 15 minutes, matey, and hit is with a coat o' Walmart Clear Coat which protects t' silver. Begad! Avast, me proud beauty! Then after 2 hours, I masked off everythin' except t' nose cone and ring-fin. I painted them with Walmart Fire Red paint on t' whole body (additional comments about Walmart paint).
Overall, ya bilge rat, ya bilge rat, for CONSTRUCTION I would rate this kit 4 ½ points. Avast, me proud beauty! Build sequence and quality/fit o' parts be excellent. Avast! Begad! Instructions are excellent. Ya scallywag! Aye aye! No decals and no pre-cut fins take away a bit. T' latter is never a problem for me, me hearties, but some may nay like it. Avast, me proud beauty! Avast! If it keeps t' costs down, then I can wield a hobby knife for some fin cutting.
FLIGHT/RECOVERY:
FlisKits recommends t' A8-3, shiver me timbers, B6-4, C6-5, and D10-5 motors.
FlisKits indicates that t' rocket should weigh 1.66 ounces.
My finished rocket weighed in at 1.7 ounces.
On December 29th, me son and I went sleddin' and I was noticin' that thar was absolutely no wind. Since I was fortunate enough t' get t' rocket painted on t' last day o' November, me bucko, I decided I should try t' fly it as well. Ya scallywag! Blimey!
So we packed up a couple o' rockets and went for a few quick launches.
I used 3 sheets o' Estes waddin' and then loaded an A8-3. T' flight has nice altitude and it was very stable. Blimey! T' Corona has a sleek, me hearties, long profile design, arrr, so it gives an effortless-look t' its flying. Ejection was a bit before apogee. Ahoy! Arrr! Recovery was good, me hearties, matey, but fast. Ahoy! Well, blow me down! I should have selected a larger 'chute when cuttin' it out (see above).
Second flight was on a B6-4. Zipped off t' pad and went quite high. Well, me bucko, blow me down! Nay a single wiggle or spin... Begad! Begad! straight as an arrow (as t' sayin' goes). Avast! Ejection was again a bit early, arrr, me hearties, me hearties, however, shiver me timbers, me hearties, no damage. Recovered without problem.
Lookin' forward t' some C flights!
For FLIGHT/RECOVERY, shiver me timbers, I would rate this rocket 5 points. Sleek and low profile gives this rocket a nice look. Well, blow me down! Blimey! It is a very stable rocket. Recovery system is fine, but I would go with a larger parachute than what I picked.
I give t' rocket an OVERALL ratin' o' 4 ½ points. Avast! This longneck is more than 3-fins-and-a-nose cone utilizin' a ring-fin for looks and stability. Begad! Avast! Nice rocket. Avast, me proud beauty! Let's get some decals and really turn it into a 5. Fliskits has made a "baffle" available for this kit, matey, ya bilge rat, me hearties, which I would have bought had it been available back when I purchased it.
This is an updated version of the FlisKits Corona. To prepare the Corona for the release of the optional Corona-2 booster, FlisKits now includes laser cut plywood fins instead of balsa fin stock and a pattern so the builder no longer has to cut out the fins. There are 3 minor changes to the build of the Corona: The builder has the choice of building the motor mount with or without the ...
This is a single stage rocket, skill level 2 from the new company FlisKits. It has an interesting fin area with a ring. It says that it was first introduced at the Seventh Annual North East Model Rocket Convention (NEMROC7). I ordered this direct from FlisKits online and had it in 2-3 days by mail. The package is very nice looking. It came in a retail type bag (like Estes) with a hole punched ...
