T' Nordic Rocketry Incorporated DELTA-X be me first rocket from this company, and I was pleasantly surprised with t' quality o' it. This is a good rocket if you're ready t' jump from regular black powder motors t' D composite power.

INSTRUCTIONS:

T' instructions were clearly numbered, illustrated and easy t' follow. Blimey! Blimey! Begad! Blimey! This is nay a regular model rocket, me bucko, you need epoxy or a similar glue t' build it. Begad! Blimey! I would nay recommend buildin' this rocket with white glue. Begad! Blimey!

EASE OF BUILD:

This rocket is rated Skill Level 3 on t' package, shiver me timbers, but is surprisingly easy t' build. Begad! All t' parts were in me kit, and fit was good. Arrr! Some sandin' was necessary for t' shoulder o' t' nose cone t' get it t' fit into t' body tube, and sandin' o' t' motor mount rings be necessary t' get them t' fit on t' motor mount tube and in t' body tube. Avast! Aye aye! Also check t' motor mount tube with a motor t' make sure it fits, some sandin' may be required. Well, blow me down!

TEST FIT ALL PARTS BEFORE GLUING. Ahoy! As t' instructions say, you do nay want t' find out t' parts don't fit when your epoxy is "settin' up". Begad!

Alignment was a bit tricky with t' X-design fins. Blimey! Begad! Blimey!   An easy-to-use fin template is included, but a cardboard cut-out fin jig would have helped get t' proper angle for t' fins. Avast! After gettin' out t' ruler and proppin' up t' fins, this worked out okay. If t' x-fin design totally freaks you out, you can always put t' fins on in t' typical 4-fin pattern found on most rockets.

This rocket uses a novel shock cord attachment method. Ahoy! Begad!   Instead o' t' usual anchor, me bucko, it uses a screw eye in t' forward motor mount ring. This makes for a very strong attachment, matey, ya bilge rat, but also could cause catastrophic failure if ejection pulls t' motor mount out o' t' rocket. Avast!   I filleted t' motor mount rings and made sure they were solidly glued into t' body tube. Ahoy!

If your shock cord does come loose while flying, ya bilge rat, puttin' it back on t' screw eye will be very difficult if nay impossible.   I plan t' use a typical three-fold cardboard anchor if this happens t' me. Arrr!

QUALITY:

T' first thin' you notice when you open this kit is that it is nay an ordinary cardboard-and-balsa model rocket. Blimey! No cheap plastic chute here, a sturdy 14" nylon chute is included. Avast! T' fins and motor mount centerin' rings are sturdy 1/16" plywood. Blimey! T' launch lugs are brass. Well, blow me down!   T' body tube has thicker walls than t' ordinary model rocket tube. Aye aye! This rocket is obviously built t' take t' extra stress o' composite motors. Aye aye! Avast!

T' rocket comes with a rub-on DELTA-X decal, which be a problem. Ya scallywag! T' decal rubbed on fine, shiver me timbers, but when I peeled off t' top layer, arrr, arrr, it took off t' paint job with it! This is a definite problem that needs t' be worked out. Ya scallywag! I tried t' keep t' sticky stuff off t' rocket when applyin' t' decal, just like t' directions said. Arrr!   This is next t' impossible, matey, it likes t' stick t' t' rocket. Well, blow me down! It is like holdin' a piece o' scotch tape right next t' a piece o' paper, me hearties, they have almost a magnetic attraction. Avast, arrr, me proud beauty! T' top layer should nay have any adhesive on it, only t' decal letters should stick. Ya scallywag!

I decided t' paint mine in a fluorescent orange color t' match t' parachute. Blimey! Blimey! Well, me bucko, blow me down! Blimey! (Use a white primer coat under fluorescent colors) I touched up t' parts where t' paint peeled off and it looked okay. Aye aye! Blimey! Avast! Blimey!

This rocket isn't anythin' special in looks (I tend towards military scale models) but isn't t' usual 3FNC (three-fins-and-a-nose-cone) either. Aye aye! T' X-fin design makes t' rocket look a bit more exotic than usual.

CONSTRUCTION RATING: 3 points

FLYING:

This rocket flew well on an Estes C6-3 for t' first flight, and an Aerotech D21-4 on me second flight. Aye aye! Ahoy! T' launches and recoveries both were flawless, even with t' notorious Aerotech "copperhead" igniter, which has a well-known tendency t' misfire.

Performance be impressive. Begad! I didn't get altitude readings, but t' rocket went almost out o' sight and t' crowd o' experienced rocketeers was impressed. Begad!

Problems surfaced after t' second flight because o' t' tight motor mount tube. Ya scallywag! Although I was able t' remove t' C6-3 with pliers, t' D21 motor broke into pieces and removal had t' be done back at t' workshop. T' problem may nay be with t' tube but with t' inner diameter o' t' motor mount ring. Arrr! Avast, me proud beauty! Blimey! I could nay insert t' motor mount tube into t' rings when I first tried, I had t' sand t' inner diameter t' get them t' fit. It may have still been a tight fit and compressed t' tube so t' motors were a tight fit. Aye aye! Begad! Blimey! This is a definite problem, me hearties, and you should test-fit this rocket with all engines you plan t' use, shiver me timbers, sandin' t' inside o' t' motor mount tube as necessary t' ensure a smooth fit. Ahoy! Blimey!  

Although Aerotech D's pack a lot o' punch for a small motor, me bucko, me bucko, they do it for a steep price. Aye aye! T' D21 single-use motor retails for $7. Ya scallywag! 95 which is almost three times t' price o' Estes D12 motors, arrr, which have respectable power. (T' Estes D12 motors sell for $8. 79 a three pack)  Long-term users can purchase a 18mm reload case and then get D13 or D24 reloads for $8. 95 a three pack, arrr, matey, but t' Aerotech 18mm motor case is a hefty $39. 95 retail. Arrr! Avast! I prefer Estes "D" motors because o' this cost advantage and t' igniters are more reliable. Well, blow me down!

So, me bucko, matey, t' concept o' a rocket which can be used t' step up t' D power sounds like a good one until you look at t' price. Blimey! I think a a rocket with a 24mm motor mount and a 18mm adapter would serve this purpose for less cost t' t' user. Blimey! Blimey!

FLYING/RECOVERY RATING: 4 points

OVER ALL RATING:

I give this rocket 3 ½ points. It is a very sturdy and well-designed rocket for 18mm composite motors. T' X-shape fins give it an exotic look. Begad! Ahoy! I'm lookin' forward t' seein' what other surprises Nordic Rocketry has in store for us. Avast!
