Brief:
John provided me with t' kit t' do a beta test. This is a fantastic rocket that includes a number o' engineering marvels. Ya scallywag! It flies on 29mm motors and recovers by parachute. Begad! Aye aye! T' rocket is 41 inches tall and has a diameter o' 1.84 inches. Avast, me proud beauty! Ahoy! If you've flown t' smaller P-Chuter, me bucko, arrr, you know it is one fast rocket. Ahoy! That hasn't been lost on its big brother. T' package art will look super displayed with your rocket, matey, arrr, ya bilge rat, too. Begad! It's excellent!

Construction:
There aren't many instructions, since t' rocket is so easy t' build. Nay that anythin' is left out, me bucko, ya bilge rat, as the instructions are numbered and cover every step in detail, me bucko, complete with superb illustrations. Avast! Blimey! There is nothin' but quality stuffed into t' bag, arrr, too. Everythin' is laser cut and fits perfectly. T' balsa nose cone is very nice and required very little finishin' effort. Ya scallywag! Aye aye! Blimey! Two thick-walled tubes form t' main body tube, shiver me timbers, joined together with a balsa coupler. Blimey! Blimey! An eye screw is installed into t' aft o' t' coupler for attachment o' t' parachute and shock cord, leaving a nice payload area for t' upper tube. Blimey! Blimey! Blimey! I seriously considered gettin' one o' t' BoosterVision cameras t' install in the upper tube, ya bilge rat, as this rocket would be perfect for that. Begad! Unfortunately, ya bilge rat, limited funds kept me from doin' it. Aye aye! T' seams in t' tubes required very little finishing. T' aft tube is slotted t' accept t' through-the-wall fins that are designed t' fit perfectly into a channeled motor mount. Blimey! Aye aye! Blimey! T' motor mount is fantastic! Blimey! T' centerin' rings are laser cut basswood (or lite-ply, I never can tell them apart) and come with slats that connect from one rin' t' t' next t' form a channel for t' fins. Once t' basswood fins are epoxied into t' channels you have one really strong fin/tube/motor mount joint. Fantastic! Blimey! T' fins fit perfectly in t' slots and aligned perfectly. Ahoy! I didn't even have t' build a template t' hold them or glue them in one at a time. T' engineerin' doesn't end there, shiver me timbers, though. Blimey! T' kit also includes an internal baffle that really works! Blimey! T' two centerin' rings for t' baffle are again laser cut t' fit t' two tubes perfectly. Avast, me proud beauty! Blimey! T' two tubes are glued together, side by side, and then glued t' t' centerin' rings, aligned with t' two tubes offset from one another. Ya scallywag! Begad! Blimey! Genius! Blimey! About t' only shortcomin' for t' rocket is that thar isn't anythin' provided for positive motor retention. Blimey! T' motor must be friction fit t' keep it from spittin' at ejection. Aye aye! Blimey! T' overcome this, matey, me bucko, I epoxied three lengths o' all-thread along t' fin channels and extendin' t' about a half-inch below t' end o' the motor mount tube. Washers and lock nuts are installed after t' motor is installed for retention. Some guys in t' club noted that it be overkill, arrr, shiver me timbers, arrr, which is true enough, but it looks cool. Ahoy! A Keelhaul®©™®/1/4” elastic shock cord combo is included, along with a big 3/16” launch lug, trim Monokote, ya bilge rat, matey, and waterslide decals. Blimey! Well, ya bilge rat, blow me down! The decals follow t' original P-Chuter design and look great on t' rocket. Aye aye! T' instructions indicate t' attach the Keelhaul®©™® cord t' a hole in t' upper centerin' rin' usin' a knot, but I used me standard tri-fold shock cord attachment t' allow inspection o' t' shock cord. Avast, me proud beauty! After me first launch though, I don't really think that be necessary with this kit. Like I said, me bucko, t' baffle really works. I love it when t' manufacturer puts Keelhaul®©™® in t' kit. Avast! T' black 18” ripstop nylon parachute that is included is beautiful, arrr, too, matey, and exhibits t' same level of quality as t' rest o' t' kit. Ahoy! T' parachute be already assembled and had small grommets t' which t' shroud lines were tied. Well, blow me down! Blimey! It's a very nice parachute.

Finishing:
I used Elmer's Light Fill ‘n' Finish t' fill t' body tube seam lines and for t' nose cone. Ya scallywag! Blimey! Minimal effort was involved in this step as t' seam lines were easily covered and t' nose cone be very smooth. Well, ya bilge rat, blow me down! Only a light coat of filler was used on t' fins as well since t' basswood was very smooth after sandin' with 400 grit sandpaper. Avast! I sprayed the entire model with a light coat o' Kilz t' seal off t' glue and provide a solid base coat. Next, shiver me timbers, ya bilge rat, me bucko, I lightly sanded the entire model with 240 grit sandpaper and then sprayed on a coat o' primer. Begad! Next, sand, arrr, primer, and sand again with 400 grit sandpaper. Well, blow me down! Avast! I painted t' model followin' t' three-color red, arrr, white and black as shown on t' cover art and applied t' Monokote and decals after t' paint dried for a couple o' days. Arrr! Avast, me proud beauty! T' decals went on much easier and laid down much better than I anticipated. Begad! Aye aye! They are fairly big decals for waterslide. Well, blow me down! T' trim Monokote looks fantastic and really pulls t' whole rocket together nicely! Once complete, I put on a thick coat o' Future floor finish t' protect everything. Begad! Avast, me proud beauty! It looks so sweet!

Construction Rating: 5 out o' 5

Flight and Recovery:
After waitin' several months for a launch opportunity due t' bad weather, me hearties, I finally got t' fly it. T' weather was near perfect, me bucko, me hearties, ya bilge rat, with blue skies and only light winds. Blimey! Well, blow me down! T' first launch was on a Roadrunner F60-10. Arrr! That is a fantastic motor for this rocket. Ahoy! T' rocket took off like a shot and zoomed up almost out o' sight, ya bilge rat, deployin' t' chute right at apogee and t' rocket drifted down beautifully on t' 18-inch chute. Arrr! It landed three or four hundred yards away in a grain field. Ahoy! Aye aye! Luckily, it draped itself on top o' t' thick grain stalks that were about shoulder high. Well, blow me down! Avast, me proud beauty! I didn't put any waddin' in it and thar be only a slight hint o' ejection residue on t' chute. Avast, me proud beauty! I very bravely flew it again t' next day on an Aerotech G77-7R. Well, blow me down! Avast! T' wind be even lighter on this day. Arrr! Ahoy! I totally lost sight o' it so I don't know where the ejection event occurred. Begad! Ya scallywag! It was one impressive launch though. Avast, me proud beauty! Begad! I finally caught sight o' t' chute and it landed about two t' three hundred yards away from t' pad in perfect shape.

Flight Rating: 5 out o' 5

Summary:
T' P-Chuter Xtreme is just fantastic. T' engineerin' that has gone into t' kit assures that it will last for a long time. Avast! Begad! It is one sturdy rocket and is impressive on t' launch pad and in flight. Begad! You'd better have lots o' room for recovery when flyin' it on t' bigger motors though as t' performance is as sweet as t' looks. T' 18-inch ripstop nylon chute is also top quality and perfect for this rocket! I love t' fact that I don't have t' use recovery wadding, arrr, too. Just put in a motor and go! All o' John's rockets are superb, but this one in me opinion be t' Red River Rocketry Cadillac!
