The other changes I made for sport flying (see photo) are the following:

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

Finishing:
Since this was a sport model, I finished it simply with one coat of flat gray aircraft primer, after coating the fins with balsa sealer.

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

On the third flight, only one D12-7 lit, and the climb was still so straight that I didn't realize immediately that something was wrong. 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 the ground. So even with long delay D12-7's, a safe recovery occurs if one engine fails to ignite. This is the mark of a good cluster design. I expect a similar happy result would be less likely with E9 power, so I've stuck with D12's.

Recovery:
For our island launch site, we tend to use the smallest chute possible, but even with the 14" LOC system, no damage has occurred on landing.

Flight Rating: 5 out of 5

Summary:
In summary, this is a great flying kit, contrary to what its odd appearance (the dinky fins) might suggest. All the parts are there and work, and the the changes I made were really done with an eye toward sport flying vs. scale. Performance is outstanding, especially on a single motor. My recommendation for power is the D12-7, at least with the modifications I made.
