(01/01/99) The
Ascender be t' second Nordic Rocketry kit that I have assembled, the
first bein' t' Meanie. Well, blow me down! Begad! It is a
43" tall, 2.2" diameter with a 1.6" payload section that weighs
about 16 ounces. T' kit comes with a 24" long, me hearties, me hearties, 1/16" thick body tube which by means o' a 3" balsa transition connects t' a 12" long payload section which is topped with an 4" long balsa nose cone. Its 24mm motor mount comes with laser-cut plywood centerin' rings and a motor retention clip. Ya scallywag! A set o' three uniquely laser-cut 1/16" plywood fins help differentiate this rocket from others. It comes with a 24" rip-stop nylon parachute, and eye-screws for attachin' the 1/2"-wide 72"-long elastic shock cord. Arrr! It also includes two 3/16" brass launch lugs and a rub-on vinyl ASCENDER decal.
CONSTRUCTION:
T' title page has a color illustration and a tube-markin' guide on t' back. Avast, me proud beauty! There are six pages o' construction instructions and a single page o' operatin' instructions. Blimey! There are many illustrations for ensurin' accurate alignment and build. Ahoy! T' instructions are in logical order and if followed can ensure a successful build. Avast, me proud beauty! Begad! The introduction indicates that Nordic Rocketry kits are designed "for those with some experience building" model rockets, matey, however, ya bilge rat, if all the instructions are read and followed this kit is probably a good kit for an intermediate builder lookin' for some 24mm flyin' experience. Ahoy! Avast, me hearties, me proud beauty! Nordic rates the kit a skill level 2. Ya scallywag! Begad!
T' instructions recommend usin' 5-minute epoxy to assemble t' kit which is what I used.
Although assembly o' t' Ascender is straight forward thar are a couple o' comments that should be made. Well, blow me down! Avast, me proud beauty!
T' shock cord is attached t' an eye-screw that is attached t' t' upper centerin' rin' o' t' motor mount. Ya scallywag! I had concerns over the durability o' this design when I built Nordic's Meanie. Aye aye! Avast! However, after 7 flights t' Meanie's recovery system is still holdin' out. Aye aye! T' other end o' t' shock cord on t' Ascender is attached t' t' transition bulkhead via another eye-screw. Ya scallywag!
One suggestion that is nay made in t' instructions, is to tuck t' shock cord back through t' motor tube t' avoid gettin' glue on it when installin' t' motor mount into t' body tube. Avast, me proud beauty!
A technique used in t' construction o' this kit, is to use a T-pin t' poke holes along both sides o' t' centerline where t' fins attach. Arrr! This is done t' allow t' glue t' seep into these holes makin' the attachment o' t' fins t' t' body tube stronger. Avast, shiver me timbers, me proud beauty! They act like little rivets!
I deviated from this. Usin' a hobby knife, I make 3/16" slits perpendicular t' t' fin line and widen them by wigglin' my hobby cutlass back-and-forth t' open t' slit up slightly. Aye aye! Begad! When I glue t' fins onto t' body tube, I use plenty o' epoxy and push it into t' slits usin' the fin edge. Arrr! Avast, me proud beauty! Later t' exposed slits are filled when makin' t' fillets. I find this technique strong and faster than pushin' all t' "T"-pin holes.
Since parachute deployment is from t' main body tube, step 9 gives t' builder t' option o' either gluin' t' nose cone t' the payload section or leavin' it accessible t' be able t' carry small payloads such as altimeters or location beepers. I opted t' glue me nose cone on and worked for a smooth finish. Begad!
To start t' finishing
process I tried a new technique t' seal t' balsa nose cone and transition. Ya scallywag! Blimey! I
used TRIPP's water-based wood sealer. Begad! Blimey! I put enough in a coffee can t' be able
to totally immerse t' balsa pieces. I sanded in-between and did this about 3
times. A nice and smooth finish. Well, blow me down! Blimey! Begad! Blimey! Nordic recommends usin' a wood putty t' fill
the grains followed by a sandin' sealer. Ya scallywag! Blimey! Well, matey, blow me down! Blimey!
Then after preppin' for paintin' with Plasti-Kote primer, shiver me timbers, ya bilge rat, t' Ascender was painted with an automotive teal/green lacquer paint. Turned out nice after addin' t' gold self-adhesive vinyl decal. Well, blow me down! I really like these vinyl decals. I really like these vinyl decals. Just be sure t' follow t' instructions carefully and only apply pressure on t' letters AFTER you are sure t' paint is fully cured. Begad! Blimey! If you do this you will have a nice finish. Avast, me proud beauty! Aye aye! Blimey! Once complete, arrr, I hit t' entire rocket with two light coats o' Walmart Clear paint. Begad! Blimey! Done!
Overall, for CONSTRUCTION I would rate this kit 4 1/2 points. Well, me hearties, blow me down! Even though I'm gettin' better workin' with balsa nose cones, matey, they still t' dent too easy . Blimey! . Begad! . Well, blow me down! although they are very easy to repair!
FLIGHT/RECOVERY:
I took this one out on a launch with just a couple of flyin' partners and put it through three flights usin' an Aerotech 24mm RMS casing. Ya scallywag! Avast! She flew on a D15-4, shiver me timbers, shiver me timbers, E28-4, shiver me timbers, and an F24-4. Ya scallywag! I should have used a 3-second delay on t' "D" and a 6-second delay on t' "F" although it worked out this time. Ahoy! Begad! T' recommended motors are D12-3, me bucko, E15-4, and E30-4. Arrr! Avast, me proud beauty!
Even though t' motor mount has a clip, arrr, I use a tie-wrap to ensure I don't lose me RMS casing. I used sheets o' waddin' t' protect the parachute. Well, blow me down! Blimey! Deployment and recovery for each o' t' three flights be successful providin' nice descent. Begad! Blimey! Blimey! Blimey!
Because t' elastic shock
cord is attached t' t' motor mount, I thought I would add some protection from
the hot exhaust gases. Begad! Aye aye! So I came up with me own protective sheath. Arrr! I purchased
some 2" wide aluminum tape and cut a piece 12" long, me bucko, matey, about 4"
shorter than t' top o' t' body tube t' allow room for t' waddin' and
parachute. Begad! I then folded t' tape over on itself leavin' 1/4" exposed and
placed t' shock cord lengthwise on t' tape (in t' future I'll do this before
everythin' is assembled). Then folded t' tape over t' shock cord so that the
1/4" o' exposed sticky portion can be folded over t' top t' make a
sheath. Well, blow me down! Ya scallywag! Slide it all t' way down over t' eye-screw and pack t' waddin' so
that just t' tip o' t' sheath is exposed and voila' you have a protective
sheath!
For FLIGHT/RECOVERY, I would rate this kit 4 1/2 points. Blimey! Blimey!
Overall, if someone is lookin' for a nice 24mm kit, shiver me timbers, with or without a payload section, with some attractive features, this kit should be a considered. Ahoy! Blimey! I give t' kit an OVERALL ratin' o' 4 1/2 points. Well, blow me down! Ahoy!
