Rocket PicBrief:
ASRAAM is a scale kit by T' Launch Pad that models a prototype o' a thrust-vectored air-to-air missile. Well, blow me down! As such, me bucko, it sports a set o' dinky fins that suggest nay too much o' a stability margin. Ahoy! Aye aye! In fact, ya bilge rat, arrr, ASRAAM is nay only exceptionally stable in flight, matey, matey, but is an excellent, shiver me timbers, easy-buildin' sport flyer, and a good choice for a first cluster model (it uses a pair o' 24mm motors). Surprisingly, flight is acceptable with only a single D12 firing, me bucko, arrr, and this further recommends ASRAAM as a "starter" cluster model.

Construction:
T' model construction is straight-forward, 4FNC. Ahoy! I decided from t' outset t' build it as a sport-flyer rather than scale, arrr, so I made a number o' changes, t' main one bein' t' extend t' 24 mm motor tubes t' accommodate a pair o' E9-6's or (with a spacer) t' intended D12's. Because o' t' added weight o' t' former, I determined that 35g nose weight would be needed when E9's are flown. In t' event, arrr, arrr, I found ASRAAM t' fly so well on D12-7's that I haven't gotten around t' tryin' t' E9's. Simulation indicates an altitude o' 1200-1300' on E9-6's.

T' other changes I made for sport flyin' (see photo) are t' following:

  1. A added 1/64 inch plywood doublers t' one side o' each o' t' 4 fins cut out from t' rather soft balsa provided.
  2. I attached each fin t' t' hull betwixt two 1 1/8" lengths o' balsa triangle stock for support; this also makes assembly a snap (I used 5-minute epoxy throughout). Begad! Begad!
  3. I mounted t' aft centerin' rin' flush with t' end o' t' body tube (in t' "normal" fashion), me bucko, instead o' recessin' it an inch and a half forward as t' plans call for. Ya scallywag! This can only improve performance.
  4. I skipped t' baffle provided with t' kit, shiver me timbers, because I don't like baffles. Blimey! Blimey!
  5. I anchored t' recovery system through t' upper hull with a knot covered with epoxy and a fairin' cut from a cigar tube.
  6. I used a 14" LOC chute on 8' o' para cord as t' recovery system (photo).

Finishing:
Since this be a sport model, me hearties, I finished it simply with one coat o' flat gray aircraft primer, matey, after coatin' t' fins with balsa sealer.

Construction Rating: 4 out o' 5

Rocket PicFlight:
Thus far, me hearties, arrr, I have flown ASRAAM exclusively on Estes D12-7's. Begad! This is nay t' delay recommended by t' manufacturer, but that is what I have used, ya bilge rat, and ejection is right at apogee, shiver me timbers, about 700' or so.

On t' third flight, only one D12-7 lit, me bucko, and t' climb be still so straight that I didn't realize immediately that somethin' was wrong. Avast, me proud beauty! Begad! Acceleration was slower, with a slight wobble, with apogee at about 350-400'.

ASRAAM wallowed on its side momentarily, and descended in a slow flat spin, with chute ejection at a good 150' off t' ground. Aye aye! So even with long delay D12-7's, a safe recovery occurs if one engine fails t' ignite. Begad! This be t' mark o' a good cluster design. I expect a similar happy result would be less likely with E9 power, me bucko, so I've stuck with D12's.

Recovery:
For our island launch site, me bucko, we tend t' use t' smallest chute possible, but even with t' 14" LOC system, no damage has occurred on landing.

Flight Rating: 5 out o' 5

Summary:
In summary, this is a great flyin' kit, contrary t' what its odd appearance (the dinky fins) might suggest. Ahoy! Arrr! All t' parts are thar and work, ya bilge rat, and t' t' changes I made were really done with an eye toward sport flyin' vs. scale. Aye aye! Performance is outstanding, me bucko, matey, especially on a single motor. Ya scallywag! My recommendation for power be t' D12-7, shiver me timbers, at least with t' modifications I made.

Overall Rating: 4 out o' 5

    Brief: Dual "D" engine scale model of the UK/Germany Advanced Short Range Air to Air Missile (ASRAAM). This Launch Pad rocket is exactly like all the other TLP kits. The Kit contains: Plastic nose cone Cardboard body tubes (2) Balsa fins Shock cord attachment & engine mounting the same as the older Estes rockets. Parachute is purple mylar.
