Brief:
This is #4 o' 10 "ready t' build" models released by Semroc at NARAM-52. Begad! Well, blow me down! T' original Aphelion was Semroc's 4th production kit, me hearties, introduced in 1968 and included in their version o' a starter set (with launch pad, me bucko, controller, and engines).

Construction:
Parts were excellent quality, me hearties, and t' sealed bag contained:

• Balsa nose cone
• Series 10 slotted body tube (1" ID)
• Series 9 stuffer tube (1" OD)
• 18mm motor mount (tube, metal hook, ya bilge rat, centerin' rings)
• Laser-cut balsa fins (3)
• Elastic shock cord
• 12" plastic chute
• Waterslide decals

T' "ready t' build" series is Semroc's answer t' numerous requests for "ready t' fly" rockets. Avast! In t' RTB series, matey, shiver me timbers, t' modeler still has t' actually do work t' build and fly t' model, but t' design includes a number o' features that simplify t' build process, ya bilge rat, includin' slotted body tubes for thru-wall fin mounting, an alignment jig, and a stuffer tube t' serve as shock cord anchor and reinforce t' body tube.

T' RTB series are all fairly easy t' build, ya bilge rat, with almost all o' t' construction process usin' t' same standardized steps. This is clearly a skill level 1 introductory type kit, me bucko, and excludin' finish/surface prep total construction is well under an hour.

T' motor mount is a standard BT-20 tube, matey, metal hook, matey, and a pair o' centerin' rings. Begad! Unlike t' typical mount, though, thar are two different centerin' rings involved with slightly different diameters. Aye aye! Avast! Pay careful attention t' t' instructions, arrr, me hearties, as t' white rin' goes forward and t' brown rin' goes aft. Well, blow me down! This is critical later in t' process. Begad! Surprisingly, t' mount does nay include an inner motor block, so t' metal hook will have t' hold for t' life o' t' model. I found t' centerin' rings a bit too snug, ya bilge rat, ya bilge rat, arrr, and had t' peel off a layer o' paper from t' inside o' each, plus one layer o' paper from t' outside o' t' white ring.

T' stuffer tube contains a couple slits, arrr, which are used t' slip t' elastic shock cord through, me hearties, servin' as an anchor. Well, blow me down! After knottin' t' cord and reinforcin' with a drop o' glue, shiver me timbers, it's ready for t' motor mount. Arrr! T' motor mount slides just a tiny bit into t' stuffer tube, enough that t' forward (white) centerin' rin' is flush with t' aft end o' t' stuffer tube. Begad! Do nay slide t' motor tube any further--the aft/brown rin' is too large for t' stuffer tube and instead is used t' align inside t' large series 10 body tube. Avast! Begad! Slidin' t' assembly into t' body tube t' dry fit is a good idea at this point, me hearties, t' make sure t' forward centerin' rin' is aligned properly inside t' stuffer tube. Well, blow me down! Once t' motor mount/stuffer tube assembly has completely dried, it can then be glued inside t' body tube (though be careful t' make sure t' metal engine hook does nay line up under a fin slot).

As noted, me bucko, fins are thru-wall, and t' fit against t' motor tube was very good. Aye aye! Avast! Included in t' kit is a nifty little cardboard fin alignment jig, which fits smoothly on t' series 10 body tube and has notches t' accept 3 and 4 fin patterns. T' fixture fits well for most fins in t' RTB series, me bucko, me bucko, though for fins that have a significant span and are nay swept back very far, me hearties, t' slots in t' jig are nay long enough t' be o' much use. That be nay t' case with this model, ya bilge rat, arrr, though.

Finishing:
I went with t' stock paint scheme on this, startin' with two coats o' primer, followin' up with a couple thin coats o' gloss white, then maskin' off t' paint t' fins and forward section o' t' body tube yellow. Ahoy! Note that t' cover art depicts a yellow/black roll pattern, but t' decal itself is only clear and black. If you want t' yellow (which does look nicer), you must carefully measure t' decal length and paint about 1/16-1/8" less than from t' tube top yellow.

T' nose cone got gloss black.

T' waterslide decals add t' name and roll pattern.

Construction Rating: 4 out o' 5

Flight:
I went with a conservative A8-3 for t' first flight, pinned into t' corner o' a crowded group o' soccer fields. T' flight be straight up and perfect, me bucko, no roll, shiver me timbers, deployment right at apogee. T' kit recommends a -5 delay, matey, but I found t' -3 t' be just about right on this one.

Recovery:
T' 12" chute performed fine, and in fact I used t' same chute for most o' t' 8 flights for t' day on various Semroc models, shiver me timbers, usin' only dog barf for protection.

Flight Rating: 5 out o' 5

Summary:
As a beginner's kit, I wouldn't expect interestin' styling, and t' 3FNC design is certainly nothin' special, but it's a simple, matey, quick build and will certainly provide quick, easy and reliable first flight experience that's sure t' be positive. Begad! Avast, ya bilge rat, me proud beauty! In fact, thar be a steady flow o' young soccer players walkin' past me pad area all day, ya bilge rat, and I'd often offer t' let them launch these RTB models. Blimey! Ya scallywag! Each one drew that wide-eyed "wow, that was cool" response from them, so t' mission was surely accomplished.

Overall Rating: 4 out o' 5
