Ever since I laid eyes on it, the Velociraptor has had a claw in my heart for a "I gotta build this..." project.
I gotta love Open Rocket. Using the .rkt file I found over on rocketreviews.com, I've been able to downscale it from a 86" long, 4" diameter, 29mm powered, monster of a rocket into something a little more manageable.
My plans are to build this as a 35.25" long, 1.64" Diameter (BT-60), 24mm powered mini-monster... However, instead of a single stage, I'm planning on a 2 stage design.
My scale work in OR has the nosecone as a 6.56" long ogive. I found Semroc's BNC-60G4 Balsa Nose Cone BT-60 6.6" Ogive an acceptable match for my needs.
I'm planning on building this with a payload section, but that isn't set in stone. To reduce the need for cutting up one of my BT-60's, I opted to make the payload section 5.78" long.
The main body tube is 18" long. I'm planning on a 24mm motor mount, capable of handling 3.75" long motors. The fins will be TTW, papered, 1/8" balsa, except for the talon fins. Those I plan to build up with a 1/32" thick plywood core and 1/16" balsa skins (to prevent me from messing up the shape in sanding). I'll sand them back down to 1/8" thick, then reinforce the leading edge with CA, and sand my taper out of the softer balsa.
The boat tail in the original is, according to Mike, the same nosecone as the nosecone used, but cut down. However, due to scaling issues, I opted to go with a cut down PNC-60RL that I had (damaged tip). My rocket will be scale in length, but the 24mm motor isn't something that I can alter. I'm happy with my solution (I should put a shout out to kjohnson for his suggestion of the PNC-60AH/RL). The shoulder of the booster's tail cone isn't shown in the image above, but will be present in the actual rocket.
I've still got some issues to work out (do I need a streamer for the booster? If so, how do I implement it? Any other options?)
I'm ordering downscaled decals are from Binder Design (Thanks Mike!).
Well, it's after 1 in the morning... I should get some sleep, I've got class in the morning. I'll add photos later.
Pointy Side Up!

[EDIT] In the early images of this build thread, I was using the fin shapes provided by rocketreviews.com's .rkt file.
