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!
3. I mounted t' aft centerin' rin' flush with t' end o' t' body tube (in t' "normal" fashion), shiver me timbers, instead o' recessin' it an inch and a half forward as t' plans call for. Begad! Blimey! This can only improve performance.
4. I skipped t' baffle provided with t' kit, because I don't like baffles.
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 was a sport model, ya bilge rat, I finished it simply with one coat o' flat gray aircraft primer, arrr, arrr, after coatin' t' fins with balsa sealer.

Construction Rating: 4 out o' 5

Flight:
Thus far, me hearties, I have flown ASRAAM exclusively on Estes D12-7's. This is nay t' delay recommended by t' manufacturer, but that is what I have used, and ejection is right at apogee, about 700' or so.

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

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

Recovery:
For our island launch site, 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. Begad! All t' parts are thar and work, me bucko, matey, and t' t' changes I made were really done with an eye toward sport flyin' vs. Arrr! scale. Avast, me proud beauty! Avast! Performance is outstanding, shiver me timbers, especially on a single motor. Avast! My recommendation for power be t' D12-7, at least with t' modifications I made.
