Back in 1977, arrr, I sent for an FSI catlog after findin' an address in t' back o' a library book. Begad! While nay as flashy as t' Centuri and Estes catalogs I was used to, arrr, arrr, thar were a couple o' designs that caught me eye back then, me bucko, specifically t' Nova and Sprint. I eventually found an original FSI Nova that I built and flew, me bucko, me bucko, but t' Sprint remained elusive. Arrr! I recently made a Semroc purchase o' parts that I thought I needed t' rebuild a Centuri Taurus upscale that I'd built and flown several years back, arrr, but found that I could reuse a lot more o' t' original parts than I thought. Ya scallywag! Avast, me proud beauty! This left me with two TA6070 transitions and no clear project for them. I hate t' waste anything, especially anythin' as well made as a Semroc balsa transition, hence me "FSI Upscale" phase.
There aren't a whole lot o' parts for this rocket, ya bilge rat, which greatly cuts down on t' chance o' gotchas. Ahoy! Well, blow me down! I love projects like that. Avast, me proud beauty! T' most work-intensive part o' t' project was drillin' out t' center o' t' TA6070 transition, which I accomplished usin' by first drillin' through t' transition with a 1/8" drill bit, matey, then takin' out enough o' t' rest o' t' material t' make a BT-50 size hole with a Dremel tool and attachment.
As with most o' me projects, me hearties, I tied a 36" piece o' Keelhaul®©™ behind t' front centerin' rin' t' anchor t' rest o' t' recovery system. This was threaded up through t' Dremel hole in t' transition and attached t' a 36" length o' 1/4" sewin' elastic. Blimey! Aye aye! A medium snap-swivel attached t' a hefty screw eye which be glued into t' nose cone bottom t' tie t' whole thin' together.
After disposin' o' t' balsa grain and tube spirals with two coats o' thinned Elmer's Carpenters Wood Filler and LOTS o' sanding, me hearties, I sprayed t' rocket with white Valspar primer. Ahoy! Blimey! Well, ya bilge rat, blow me down! Blimey! I then sprayed one fin with Rustoleum Flourescent Orange, shiver me timbers, me hearties, completely masked it off down t' t' body tube, then burnished t' edges o' t' tape t' keep any o' t' paint t' come from seepin' in. T' main body tube was sprayed with Valspar gloss white, arrr, matey, while t' nose cone and everythin' below t' transition was painted with Valspar gloss black. When all be dry I unmasked t' orange fin and as usual, was pleasantly surprised at t' "pop" that t' flourescent paint provides. Well, blow me down! Blimey! I had no decals planned, but with t' white, arrr, me bucko, orange and black scheme I was reminded o' t' Cincinnati Bengals, me bucko, matey, and found a photo o' a vintage logo that I remembered from grade school that was perfectly sized for t' upper body tube. Ahoy! Blimey! Arrr! Blimey! I'm nay sure how this ties in with t' whole Sprint thing, arrr, me bucko, but it sure beats a big, blank section o' white body tube.
To date I've made only one flight with t' Sprint, but that was due t' a backlog o' first flight mid-power kits more than anythin' else. Loaded with an Estes E9-4, ya bilge rat, me hearties, t' rocket lifted off with authority and immediately began t' windcock. Arrr! Ejection occurred as t' rocket was approachin' horizontal due t' t' wind, me hearties, but recovery was perfect and t' rocket recovered deep in t' cornfield on t' 12" nylon chute, ya bilge rat, so deep that it initially appeared t' be in a neighborin' cornfield. Ahoy! (This would have been a problem as thar be a decent size creek that separates t' two cornfields.) T' recovery walk be long, and t' search took me t' areas o' t' field where few humans had previously trod, me hearties, but along t' way I found two rockets belongin' t' other fliers. Avast, me proud beauty! Arrr! (Second time I've done that.) After thirty minutes I finally caught a flash o' orange and walked right over t' t' rocket, which appeared t' be sittin' in a spot I'd passed at least twice. Avast, ya bilge rat, me proud beauty! I swear I did. Begad! T' rocket be undamaged, but t' length o' t' recovery walk on t' 12" chute had me wonderin' how much further it would have been with a 15" or 18" chute.
Flight Rating: 5
Pros: Classic lines, impressive performance on Estes E9, ease o' construction.
Cons: Central Ohio cornfields are windy!
