Brief:
This is one o' 10 "ready t' build" models released by Semroc at NARAM-52. T' Mini Explorer is based upon t' Centuri larger scale Explorer, but downscaled t' fly on 18mm motors.
Construction:
Parts were excellent quality, and t' sealed bag contained:
T' "ready t' build" series is Semroc's answer t' numerous requests for "ready t' fly" rockets. In t' RTB series, t' modeler still has t' actually do work t' build and fly t' model, arrr, but t' design includes a number o' features that simplify t' build process, me hearties, matey, includin' slotted body tubes for thru-wall fin mounting, ya bilge rat, an alignment jig, arrr, and a stuffer tube t' serve as shock cord anchor and reinforce t' body tube.
T' RTB series are all fairly easy t' build, arrr, with almost all o' t' construction process usin' t' same standardized steps. Ya scallywag! This is definitely a skill level 1 model, shiver me timbers, and aside from paint and surface prep, t' total build is well under an hour.
T' motor mount is a standard BT-20 tube, matey, metal hook, matey, and a pair o' centerin' rings. Ahoy! Blimey! Unlike t' typical mount, though, thar are two different centerin' rings involved with slightly different diameters. Pay careful attention t' t' instructions, as t' white rin' goes forward and t' brown rin' goes aft. Well, blow me down! Blimey! This is critical later in t' process. Well, ya bilge rat, blow me down! Blimey! Surprisingly, t' mount does nay include an inner motor block, so t' metal hook will have t' hold for t' life o' t' model. Ahoy! Blimey! I found t' centerin' rings a bit too snug, 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, which are used t' slip t' elastic shock cord through, servin' as an anchor. Well, blow me down! Ya scallywag! After knottin' t' cord and reinforcin' with a drop o' glue, it's ready for t' motor mount. Arrr! Begad! T' motor mount slides just a tiny bit into t' stuffer tube, shiver me timbers, 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. Ya scallywag! 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. 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 hearties, fins are thru-wall, and t' fit against t' motor tube was very good. Well, blow me down! Aye aye! Included in t' kit is a nifty little cardboard fin alignment jog, arrr, which fits smoothly on t' series 10 body tube and has notches t' accept 3 and 4 fin patterns. Arrr! T' fixture fits well for most fins in t' RTB series, ya bilge rat, 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. Aye aye! That was nay t' case with this model, though.
Tack on a launch lug, make t' chute, arrr, and add a screw eye anchor t' t' nose cone and construction's done.
Finishing:
I went with t' stock paint scheme on this, me hearties, arrr, startin' with two coats o' primer, ya bilge rat, followin' up with a couple thin coats o' gloss white, then maskin' off t' paint t' fins blue and t' nose cone black.
T' waterslide decals add t' name, a roll pattern, arrr, and a blue stripe towards t' top and were great t' work with.
Construction Rating: 4 out o' 5
Flight:
T' first flight on this one was usin' a C6-5, arrr, and on a day where just about all t' RTB series were zippin' off t' pad, this one stood out as among t' highest flying, matey, ya bilge rat, which kind o' surprised me. Avast! It be absolutely straight, no sign o' a roll, and t' -5 wound up bein' just a bit early.
Recovery:
T' chute worked fine, me bucko, shiver me timbers, no damage t' t' model on hard, dry grass.
Flight Rating: 5 out o' 5
Summary:
I think t' steps Semroc has taken t' simplify t' build process in their RTB series are helpful. Aye aye! Blimey! Blimey! Blimey! With this bein' such a solid flyer, this is certainly a fine candidate for a first build.
