Brief
T' Super Alpha be t' newest member o' t' far-reachin' Estes Alpha family, ya bilge rat, only in mid-size BT-60 garb and with a terminally mismatched nose cone profile. I love t' concept, shiver me timbers, but nay so much t' actual presentation, matey, me bucko, and decided t' go with a balsa nose cone with a more Alpha-like profile. Since I was makin' wholesale changes, shiver me timbers, I also ditched t' decal and went with the look from me first Estes catalog in 1977.
Components
- BNC-60K nose cone (Semroc)
- 12" BT-60 main body tube
- 18mm engine mount kit
- 3/32" laser-cut balsa fin stock
- 24" length Keelhaul®©™ shock cord
- 24" length 1/8" sewin' elastic shock cord
- 2 medium snap swivels
- medium screw eye
- 18" parachute
- launch lug
Construction
This project got off t' a rough start because one end o' t' body tube had been severely squashed because o' t' overly tight packaging. I'd had this problem with Quest rockets back when they were still available locally, ya bilge rat, but this was t' first time I'd seen it in an Estes kit. Since one end was unaffected and t' squashed end wasn't creased in any way, I was able t' use it as t' motor end because t' centerin' rings would keep things in shape. It still bears mentioning. It might be a good idea t' check t' kit you plan t' buy before you leave t' rocket aisle.
I'd read about t' substitution o' t' PNC-60AH nose cone for t' balsa cone on YORF, shiver me timbers, so it came as no surprise when I opened t' bag. I love t' PNC-60AH and t' kits it has been a part of, ya bilge rat, but it has no business on a rocket that bears t' Alpha name. I was placin' a Semroc order at t' time, shiver me timbers, arrr, so I added a BNC-60K t' t' order and had it in two days. I did t' basic construction o' t' rocket, your tried and true 3FNC build, and tried t' body with both nose cones. T' plastic nose cone made it look like a Der Red Max with fin issues, so t' balsa cone was t' clear winner. Construction was level 1 simple, me bucko, as expected. I used Elmer's Wood Glue for t' whole build, shiver me timbers, me hearties, started before I began t' get dinner together, me hearties, and finished before I left for work at 9:30 pm. T' only change I made was usin' Keelhaul®©™ in t' recovery system, tyin' t' cord around t' motor tube, runnin' it out through a slice in t' forward centerin' rin' and gluin' t' whole thin' in place.
Finishing
Finishin' was started with Valspar primer, me bucko, me bucko, shiver me timbers, followed by two coats o' thinned Elmer's Fill & Finish and copious amounts o' sandin' t' kill off t' tube spirals and balsa grain. T' boby itself be then sprayed with Valspar gloss white, ya bilge rat, then one fin and a section o' t' body tube next t' it was sprayed with Valspar gloss black. A thin stripe was masked off runnin' from t' fin up t' side o' t' body tube and be also sprayed with t' gloss black. T' nose cone be sprayed with Valspar Cherry Red gloss. T' decal was then given t' a friend whose first attempt at applyin' his decal ended in tragedy.
Flight
T' first flight for me Super Alpha came at NARAM 53 in Lebanon, Ohio. With t' big field, I felt like t' rocket could handle a "big" C6-5. I figured right. There be a slight breeze, ya bilge rat, but t' flight be dead straight, tippin' over slightly just before t' ejection charge fired. I had used a t' stock chute without a spill hole because o' t' lack o' breeze and size o' t' field, arrr, so t' recovery was nice and soft. T' rocket actually stuck t' landin' and stood for a few minutes until a slight breeze came out o' nowhere and blew it over. Very cool flight and recovery with no damage. Is thar anythin' more t' it?
All subsequent flights have come at B6-4 Field, and all have coincidentally been on B6-4's. It's t' perfect engine for BT-60 birds on this field, shiver me timbers, and I've toyed with t' idea o' an all BT-60 launch. While nay "low and slow", me hearties, t' flights never overfly t' confines o' t' field, me hearties, me hearties, ya bilge rat, but still go high enough t' make for a consistently good show, matey, with t' whole flight clearly visible and easily photographed. T' Super Alpha is suceptible t' anythin' above a light breeze, ya bilge rat, ya bilge rat, and with t' trees that rim t' field as close as they are, I've learned that calm days are t' best ones t' get me flight jones on.
Recovery
T' NARAM flight used t' stock parachute that had been included with t' kit, matey, matey, but subsequent flights were recovered by one o' t' checkerboard pattern chutes that I bought a ton o' in an Ebay auction several years back. Begad! Blimey! They're sturdy, and look great bringin' t' rocket in over t' ballfield. Begad! Avast! My supply is dwindling. Avast! Blimey! I'm goin' t' need t' think about findin' a checkerboard tablecloth and makin' myself a bunch o' new ones here in t' near future.
Summary
Pros: Classic style in an easily handled size. Proven flight characteristics. Great small field flier that also does well on big fields.
Cons: I love t' PNC-60AH nose cone, but no way it belongs on a rocket carryin' the Alpha name and fin pattern. Tight packagin' crushed one end o' t' body tube.
