Brief:
This is #4 o' 10 "ready t' build" models released by Semroc at NARAM-52. T' original Aphelion be Semroc's 4th production kit, ya bilge rat, introduced in 1968 and included in their version o' a starter set (with launch pad, me hearties, matey, controller, me bucko, shiver me timbers, and engines).

Construction:
Parts were excellent quality, ya bilge rat, 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, me hearties, metal hook, shiver me timbers, 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. Blimey! In t' RTB series, ya bilge rat, arrr, t' modeler still has t' actually do work t' build and fly t' model, matey, but t' design includes a number o' features that simplify t' build process, me hearties, includin' slotted body tubes for thru-wall fin mounting, arrr, arrr, 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, with almost all o' t' construction process usin' t' same standardized steps. This is clearly a skill level 1 introductory type kit, and excludin' finish/surface prep total construction is well under an hour.

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

T' stuffer tube contains a couple slits, which are used t' slip t' elastic shock cord through, servin' as an anchor. After knottin' t' cord and reinforcin' with a drop o' glue, it's ready for t' motor mount. Avast, me proud beauty! 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. 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. Well, blow me down! Slidin' t' assembly into t' body tube t' dry fit is a good idea at this point, t' make sure t' forward centerin' rin' is aligned properly inside t' stuffer tube. Begad! 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, fins are thru-wall, matey, and t' fit against t' motor tube be very good. Ya scallywag! 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. Ya scallywag! Ahoy! T' fixture fits well for most fins in t' RTB series, me bucko, though for fins that have a significant span and are nay swept back very far, t' slots in t' jig are nay long enough t' be o' much use. Aye aye! That be nay t' case with this model, 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, ya bilge rat, then maskin' off t' paint t' fins and forward section o' t' body tube yellow. Aye aye! Note that t' cover art depicts a yellow/black roll pattern, ya bilge rat, shiver me timbers, me bucko, but t' decal itself is only clear and black. Avast, me proud beauty! 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, shiver me timbers, pinned into t' corner o' a crowded group o' soccer fields. Aye aye! Begad! Blimey! T' flight was straight up and perfect, no roll, deployment right at apogee. Avast! Blimey! T' kit recommends a -5 delay, but I found t' -3 t' be just about right on this one.

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

Flight Rating: 5 out o' 5

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

Overall Rating: 4 out o' 5
