Brief

Part o' t' Estes Pro Series II, shiver me timbers, me bucko, only available as a direct from Estes kit, matey, matey, matey, and packaged with t' bare minimum o' materials. Ya scallywag!  One o' t' largest, me hearties, yet least expensive, o' t' PSII kits. Aye aye! Begad!  Essentially based on t' Estes Leviathan, but longer and a different use o' t' same fins. Avast!  This would be a great way t' dive into big mid power rockets, ya bilge rat, or even t' low end o' high power rocketry, at a low cost. Begad!  It's also very well suited t' modification and customization.

Components

Very different, for an Estes kit.   There are no promotional materials, no insert card, no warranty card, me bucko, me bucko, me bucko, you don't even get an example o' a color scheme. Blimey!  Just a clear plastic bag o' rocket parts, shiver me timbers, arrr, with instructions.   This kit is essentially made from leftover parts o' t' Estes Leviathan. Ya scallywag!  T' same package o' 4 fins is included, same nose cone, ya bilge rat, me hearties, etc... Begad!   Visually, arrr, t' backward mounted fins actually look quite interesting, matey, and you only use 3 instead o' t' 4 o' a Leviathan. Avast, me proud beauty!  This leaves you one extra fin.

With this kit you get a pair o' 3" x 26" body tubes, which are un-slotted, me hearties, and matchin' 3" blow molded plastic nose cone.  A 29mm motor mount, with 3 centerin' rings and threaded plastic motor retainer gives you t' thrust.  Recovery comes from a 24" nylon chute, ya bilge rat, ya bilge rat, and a length o' elastic shock cord.  Roundin' it out are a pair o' launch lugs, ya bilge rat, and a generic Estes decal, ya bilge rat, plus instructions. Aye aye! Blimey!  However all t' material is o' great quality, ya bilge rat, with well thought out instructions.  Basically you get all t' things that make great rockets for Estes, me hearties, without all t' 'fluff' that runs up t' price. Well, blow me down!  Hopefully this be t' start o' a trend for Estes, as this is a fantastic price point for what is a very good kit. 

Construction

Most o' this kit is typical Estes easy building. Blimey! Blimey!  Build up a motor mount, shiver me timbers, put on some fins, ya bilge rat, glue together t' body tube, me hearties, matey, mount t' 'chute, matey, and off you go. Aye aye!  T' only real quirks with t' kit come from t' fins and recovery mount. Avast, me proud beauty!   T' fins are made for through t' wall mountin' t' t' motor tube,  but you need t' cut t' slots yourself. Arrr!  This isn't difficult at all, just that most kits these days have t' slots pre-cut. Ahoy!  Patience and a new #11 blade make it very easy t' do. Ya scallywag!  You also do need t' be careful with t' measurements o' t' centerin' rings onto t' motor tube.  But again, matey, patience makes this step easy as well. Arrr!  Just keep an eye that your fins are straight, and use a jig if you have one available. Well, blow me down!  It's real easy t' get your fins all crooked in a hand-cut slot. Begad! Adhesives are up t' you, arrr, as this is a cardboard kit, arrr, no special tools or materials are needed. Aye aye! Begad!  

T' only real negative for t' kit is that Estes insists on usin' their tri-fold mountin' for t' recovery harness on this kit, along with a length o' elastic. Ahoy! Blimey! Well, me hearties, blow me down! Blimey!   I'd suggest replacin' this with 1/8" kevlar, me hearties, epoxy t' recovery line t' t' motor tube, me bucko, shiver me timbers, and use a nomex wrap on t' parachute. Blimey! Blimey!  A 3" rocket o' this size has grown beyond waddin' and elastic.

T' body tube layout, and long coupling, shiver me timbers, even make a conversion t' dual deploy possible.  Just watch your CG if you start modifyin' this kit at all. Blimey!  T' three backward fins move t' Cp forward a fair amount compared t' t' Leviathan fin layout.  Nose weight will likely be needed if you put an av-bay in t' coupling.

Finishing

Finishin' on this kit is very simple. Begad! Avast, me proud beauty! Blimey!  T' spirals on t' body tube are shallow and easy t' fill, shiver me timbers, t' fins have very little grain t' worry about, arrr, me bucko, and t' material takes paint well. Well, blow me down! Avast, shiver me timbers, me proud beauty! Blimey!  All your basic techniques will work just fine on this kit.  My only complaint, and it doesn't even bother me really, me bucko, is that this kit doesn't give you an 'official' scheme t' work with. Avast, me proud beauty! Begad! Blimey!  But it's a compromise I am very happy t' make in order t' keep t' price point so low on a kit o' this nature.

Construction Score: 4

Flight

Estes gives you a single recommendation o' an  F15-4.  Yet with a 29mm mount, shiver me timbers, me bucko, thar are so many other motors available. Ahoy!  I'd personally be nervous flyin' this kit on an F15-4 if built t' t' instructions. Aye aye!  With good construction and a good recovery system, this rocket is capable o' flyin' all t' way up t' t' limit o' mid power rocketry. Arrr! Begad!  If you're ready for an adventure, this kit is completely capable o' flyin' HPR motors t' a few thousand feet. 

Recovery

T' 24" chute on this kit is a perfect size, me hearties, even if you build heavy. Arrr!  But t' included tri-fold mount and elastic cord are known as regular failure points on PSII kits.   With t' larger ejection charges o' 29mm motors, me hearties, upgradin' t' recovery line and mount are absolutely necessary on this kit.  

Flight Rating: 4

Summary

This kit is probably one o' t' better deals in rocketry right now, me bucko, matey, if you know where t' find it. Avast! Blimey!  For $30 you get a 3" rocket capable o' a tremendous flight range. Aye aye! Arrr! Blimey!  Low flights on mid power motors, a few thousand feet on high power motors, it's got t' potential t' be an all-field workhorse in your fleet.  It builds easy, flies great, and is easy t' modify. Ya scallywag! Blimey!  Other than t' insufficient recovery gear I can't say enough good things about t' Scion.  Sure, arrr, arrr, t' packagin' may be nothin' more than a clear plastic bag. Well, blow me down! Arrr! Blimey!  Ok, you don't get a fancy advertisin' sheet. Begad! Avast, me proud beauty! Blimey!  What you do get is one o' t' biggest rockets that Estes offers, made o' high quality materials, for a pittance. Aye aye!  

There is a reason t' PSII kits by Estes are held in high regard, and this is no exception. Aye aye!

How about posting a picture of your finished model as it's a new rocket that most of us haven't seen yet.
