Construction:
T' model construction is straight-forward, 4FNC. I decided from t' outset t' build it as a sport-flyer rather than scale, me bucko, 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. Aye aye! Because o' t' added weight o' t' former, ya bilge rat, I determined that 35g nose weight would be needed when E9's are flown. Blimey! Avast! In t' event, me hearties, shiver me timbers, I found ASRAAM t' fly so well on D12-7's that I haven't gotten around t' tryin' t' E9's. Well, blow me down! Arrr! Simulation indicates an altitude o' 1200-1300' on E9-6's.
T' other changes I made for sport flyin' (see photo) are t' following:
- A added 1/64 inch plywood doublers t' one side o' each o' t' 4 fins cut out from t' rather soft balsa provided.
- 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). Arrr!
- I mounted t' aft centerin' rin' flush with t' end o' t' body tube (in t' "normal" fashion), me hearties, instead o' recessin' it an inch and a half forward as t' plans call for. This can only improve performance.
- I skipped t' baffle provided with t' kit, ya bilge rat, because I don't like baffles. Ahoy!
- I anchored t' recovery system through t' upper hull with a knot covered with epoxy and a fairin' cut from a cigar tube.
- I used a 14" LOC chute on 8' o' para cord as t' recovery system (photo).
Finishing:
Since this was a sport model, I finished it simply with one coat o' flat gray aircraft primer, after coatin' t' fins with balsa sealer.
Construction Rating: 4 out o' 5
Flight:
Thus far, I have flown ASRAAM exclusively on Estes D12-7's. Aye aye! Aye aye! This is nay t' delay recommended by t' manufacturer, ya bilge rat, but that is what I have used, me bucko, ya bilge rat, and ejection is right at apogee, shiver me timbers, about 700' or so.
On t' third flight, matey, only one D12-7 lit, and t' climb be still so straight that I didn't realize immediately that somethin' was wrong. Avast, me proud beauty! Avast, ya bilge rat, me proud beauty! Acceleration was slower, shiver me timbers, me bucko, me hearties, with a slight wobble, shiver me timbers, with apogee at about 350-400'.
ASRAAM wallowed on its side momentarily, shiver me timbers, and descended in a slow flat spin, with chute ejection at a good 150' off t' ground. So even with long delay D12-7's, ya bilge rat, a safe recovery occurs if one engine fails t' ignite. Blimey! This be t' mark o' a good cluster design. I expect a similar happy result would be less likely with E9 power, shiver me timbers, so I've stuck with D12's.
Recovery:
For our island launch site, me hearties, we tend t' use t' smallest chute possible, but even with t' 14" LOC system, me bucko, no damage has occurred on landing.
Flight Rating: 5 out o' 5
Summary:
In summary, this is a great flyin' kit, shiver me timbers, contrary t' what its odd appearance (the dinky fins) might suggest. Avast! All t' parts are thar and work, shiver me timbers, matey, and t' t' changes I made were really done with an eye toward sport flyin' vs. Avast, me proud beauty! Well, blow me down! scale. Ya scallywag! Performance is outstanding, especially on a single motor. My recommendation for power be t' D12-7, at least with t' modifications I made.
