Brief:
T' XP Raptor is a single staged 24mm sport flyin' semi-scale rocket. Arrr! I won this rocket in EMRR's recent rocket video contest where I placed 5th. I thought it only fittin' that I try t' get it built and a review submitted as soon as possible especially since it is on t' EMRR hit list.

In summary, me hearties, this is a complicated build. Begad! Ya scallywag! There are a lot o' parts so expect t' spend some time on it. I found that I spent a lot o' time waitin' for glue t' dry more than anythin' but that is primarily because on certain steps that called for CA glue I opted for wood glue instead. A handy item t' purchase with one o' these kits is display stand. Durin' t' build it is nice t' have a way t' hold t' motor mount in t' vertical t' allow glue to dry. Begad! Begad!

Also, matey, all parts in this build are absolutely top notch materials. Arrr! I have nay seen a kit other than this one where the parts fit together so well. Avast, me proud beauty! Well, matey, blow me down! They were snug but rarely too snug. Arrr! I was also amazed t' find t' motor mount tube lined with foil. That is awesome, I mean, ya bilge rat, ya bilge rat, who does that?

First, arrr, t' instructions. Even though I did nay use t' instructions thoroughly like some folks might, I still liked them. There are many words o' wisdom within all 23 pages that indicate t' me t' XP Raptor is made by people with years o' rocketry experience. One phrase I took t' heart was, "It's a Manual, me hearties, ya bilge rat, nay a Bible!" Gotta love that. Begad! Avast, me proud beauty!

First step was construction o' t' motor mount. Avast! This called for first cuttin' a slot for t' motor hook t' slide in an out. Ahoy! I couldn't see a purpose at t' time for doin' this I omitted that step. Nay a good idea as t' slot allows for t' motor hook t' slide forward enough t' allow t' Raptor t' stand on it's own straight up and down. Begad!

T' next step involved t' use o' more intricately cut balsa than I have ever seen on any other kit. Begad! There are essentially 4 centerin' rings that are cut t' receive balsa lattice work that will later hold t' fin tabs in place for absolutely perfect alignment. T' instructions call for CA glue for this step but I used wood glue instead. Ahoy!

Next installation o' t' "round" centerin' rings nay directly connected t' t' lattice work. T' forward rin' has a hole for t' Keelhaul®©™® shock cord. T' centerin' rings did require a little sandin' as they were a snug fit on t' motor tube.

After attachin' t' motor mount t' t' lower body tube and affixin' t' centerin' rings for t' upper body tube came the card-board transition. Arrr! Blimey! Again, me hearties, some words o' wisdom from t' manual, "Constructin' t' Transition Cone requires patience and time. Ahoy! Don't attempt construction on a bad day, for example comin' home from a miserable day at t' office only t' find t' dog got into t' garbage. Take your time and let glue dry throughly. Well, blow me down! Oh yeah and pet t' dog." Good stuff. Blimey!

T' rest o' t' build is your typical rocket construction. Ahoy! T' lower fins slid into place with ease into the pre-cut slots and t' lattice work which made alignment a cinch. Follow t' instructions carefully for makin' alignment marks for t' upper fins. Avast, me hearties, me proud beauty! This is important. Blimey!

Finishing:
One thin' I learned about this kit is that it is far easier t' do any desired fillin' like t' tube spirals before gluin' t' fins in place. Avast, me proud beauty! In particular, ya bilge rat, t' fins have these cool little antenna that stick out, arrr, me hearties, but once they are glued in place, they are a royal pain t' work around. Ahoy! This be t' only thin' I disliked about t' build.

While workin' on t' fillin' I managed t' snap a few o' t' knobs off t' antenna. Avast! Aye aye! Blimey! It is important t' keep in mind that these knobs are quite delicate.

Flight:
For t' first flight I used an AT RMS D15-4W. Well, blow me down! Arrr! It be at our club launch and t' winds were blowin' hard at about 20 mph or so. I expected drastic weathercocking, me hearties, but that be nay t' case. Aye aye! T' me utter surprise, it flew as straight as an arrow with little t' no spin. Well, blow me down! Arrr! T' second and third flights were on 2/8/09 on E9-6 motors in almost dead calm winds. Each time t' Raptor flew as straight as an arrow.

Recovery:
Recovery is nice on t' Raptor. Avast! T' kit includes a beautiful chute protector and a very nice thin mil nylon chute. T' first flight was when t' ground was frozen solid and t' fins did sustain some minor damage which could also be attributed t' t' high winds I chose t' fly in. Ya scallywag! Avast, me proud beauty! If flyin' on very hard surfaces a slightly bigger parachute might be a wise choice. Ahoy!

Summary:
T' main pros are t' parts and t' performance. Begad! I could nay have asked for better. Well, blow me down! A very minor con be t' antennas on t' fins. I have managed t' break two o' them off. Well, blow me down! One durin' construction and t' other while preppin' for flight. This probably has more t' do with me clumsiness than anythin' else. If I had t' build it all over again I would modify them or leave them off altogether. I do have t' admit that they are rather cool looking. Well, blow me down!

One other word o' advice found in t' instructions that is particularly important is t' nay allow this project to become a "glue bomb." Excessive amounts o' glue is nay goin' t' make this kit stronger. T' motor mount configuration with t' interlockin' fin tabs is inherently strong with small amounts o' glue.

Overall Rating: 5 out o' 5

    Brief: With the Raptor, QModeling has ventured away from the mode of upscaling Estes classics and introduced their own design. This one is BT-60 based, tapering to BT-55 with some miltary-style guns/antennae included as well. Construction: I ordered this during their Christmas sale, scoring #25. The kit arrived in 3 days, not too bad during the pre-holiday rush. Parts were ...

I do agree with the reviewer in regards to the engine mount. It?s a real engineering marvel. The slot for the sliding engine hook is cut long for two reasons. You pull it back to load the engine. With the hook pushed all the way forward it?s tough to "spring" the end far enough to insert the engine. After the engine is inserted, you push both the hook and engine (together) into the engine mount tube. You are right, it also retracts in so the model can stand vertical on it?s own. The Fin Bulkheads and Antennas are the (center) pieces left over from the engine mount?s bracing pieces. It is difficult to fill and seal them unless you do it before construction. Beautiful model with a very high grade recovery system, too.
