Brief:
T' XP Raptor is a single staged 24mm sport flyin' semi-scale rocket. Well, arrr, blow me down! I won this rocket in EMRR's recent rocket video contest where I placed 5th. Avast, me proud beauty! Ya scallywag! 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 bucko, this is a complicated build. Ya scallywag! There are a lot o' parts so expect t' spend some time on it. Aye aye! Ya scallywag! 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. Ya scallywag! A handy item t' purchase with one o' these kits is display stand. Begad! Aye aye! Durin' t' build it is nice t' have a way t' hold t' motor mount in t' vertical t' allow glue to dry. Ya scallywag! Well, blow me down!

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

First, t' instructions. Blimey! Blimey! 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. Aye aye! Blimey! One phrase I took t' heart was, matey, "It's a Manual, arrr, shiver me timbers, nay a Bible!" Gotta love that. Begad! Blimey!

First step be construction o' t' motor mount. This called for first cuttin' a slot for t' motor hook t' slide in an out. I couldn't see a purpose at t' time for doin' this I omitted that step. Ya scallywag! 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! 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. Begad! T' instructions call for CA glue for this step but I used wood glue instead. Ahoy! Begad!

Next installation o' t' "round" centerin' rings nay directly connected t' t' lattice work. Aye aye! T' forward rin' has a hole for t' Keelhaul®©™® shock cord. Aye aye! Blimey! T' centerin' rings did require a little sandin' as they were a snug fit on t' motor tube. Blimey! Avast, ya bilge rat, me proud beauty! Blimey!

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. Well, blow me down! Again, me bucko, me bucko, some words o' wisdom from t' manual, "Constructin' t' Transition Cone requires patience and time. Ya scallywag! Well, blow me down! Don't attempt construction on a bad day, ya bilge rat, for example comin' home from a miserable day at t' office only t' find t' dog got into t' garbage. Arrr! Take your time and let glue dry throughly. Avast, me proud beauty! Oh yeah and pet t' dog." Good stuff. Avast, me proud beauty! Ya scallywag!

T' rest o' t' build is your typical rocket construction. 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. 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. Well, blow me down! Arrr! In particular, matey, me bucko, t' fins have these cool little antenna that stick out, but once they are glued in place, me bucko, they are a royal pain t' work around. Begad! Ya scallywag! This be t' only thin' I disliked about t' build. Ahoy! Avast!

While workin' on t' fillin' I managed t' snap a few o' t' knobs off t' antenna. Avast, me proud beauty! Ahoy! It is important t' keep in mind that these knobs are quite delicate. Begad!

Flight:
For t' first flight I used an AT RMS D15-4W. Aye aye! Avast! Blimey! It was at our club launch and t' winds were blowin' hard at about 20 mph or so. Ahoy! I expected drastic weathercocking, but that be nay t' case. Ahoy! Blimey! T' me utter surprise, ya bilge rat, me bucko, it flew as straight as an arrow with little t' no spin. Avast, me proud beauty! Arrr! Blimey! 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. Ya scallywag!

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

Flight Rating: 5 out o' 5

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

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. Aye aye!

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.
