Brief:
T' Maxi Streak #1837 is a long time OOP rocket from Estes. Begad! Avast, me proud beauty! Blimey! Got t' plans off JimZ's website. Well, blow me down! Blimey! It is like an upscaled mosquito with swept back fins or a streak with rounded fins and upscaled. Ya scallywag! Blimey! T' instructions call for a 24mm motor mount, which I changed for an 18mm mount: a D or E motor would put this thin' into space.
Modifications:
T' maxi streak is a very quick build. Ahoy! T' instructions are o' t' normal Estes quality. I don't like t' tri fold method for anchorin' t' shock cord, matey, instead I use a steel fishin' leader attached t' t' motor mount, ya bilge rat, ya bilge rat, this also stop burnin' issues t' t' shock cord.
T' mount was glued into t' body tube, matey, t' instructions called for t' end o' t' mount t' extend beyond t' end o' t' tube, ya bilge rat, I put it in flush t' give t' rocket a cleaner line.
Construction:
T' build t' Maxi Streak is used: 1 engine holder BT-20J
Finishing:
T' fins o' t' model were given a few coats o' sandin' sealer and t' rocket be primed and sanded.
T' rocket was given several light coats o' metallic red paint, ya bilge rat, after this dried one fin be masked off and given a few coats o' gloss black paint, as was t' nosecone.
I went with red paint, matey, because t' picture o' t' Maxi Streak on t' Jimz site has t' rocket in red. Begad! however, me bucko, ya bilge rat, t' instructions have t' rocket bein' painted orange, matey, which I read after i had painted mine - so that's another deviation from t' original.
Initially I was nay goin' t' put a decal on t' rocket, me bucko, but after postin' this build on TRF, me hearties, Gordy from excelsiorrocketry said he had one and as i have been very happy with t' quality o' his decals in t' past i bought one t' finish t' model properly. Ya scallywag! Blimey! Gordy has since told me that he has sold a few more Maxi Streak decals t' other poeple.
Flight:
T' original recommended motors were D11-9, matey, D12-5, me hearties, matey, D12-7. Ahoy! With t' 18mm mount i would go with A8-3, B6-4, C6-5.
Flights were made with all three motors in t' same day. Avast! Each flight be arrow straight, arrr, with a steady increase in altitude.
I got t' drag race me Maxi Streak against another Maxi Streak at me club's monthly meetin' on t' 21st o' March. I lost.
Recovery:
T' original Maxi Streak recovered via a streamer, shiver me timbers, given t' low mass and potentially high altitude then that's a good choice.
I went with about 4 foot o' two-inch wide Mylar streamer.
Recovery is quite fast, but safe. Begad! Each flight had t' streak land fairly near t' pad and more importantly without damage.
Summary:
Pros: A good performance rocket that looks good, arrr, especially with t' excelsoirrocketry decal. Aye aye! Aye aye! Flights are stable and fast.
Cons: Streamer recovery may result in some damage t' t' swept back fins, ya bilge rat, but none has been seen yet.
