Step 10: Camera bay cover

The camera bay is covered by a piece of plastic cut from a 1-liter soda bottle. It is taped in place with clear tape once the camera is turned on and placed in the bay in preparation for flight. 

I'm excited to get some great shots with it. Watch out neighbors!
Here is my first video from this rocket... probably more to follow. Thanks for taking a look!<br> <br> <div class="media_embed"> <iframe frameborder="0" height="360" src="http://www.youtube.com/embed/hB-UqE1aeqw" width="480"></iframe></div>
<p>Is it necessary to have 3 engines? Will it fly with 1?</p>
<p>There are higher-power motors available, so you could use just one in that case. They run $10-ish each, which is a lot, but about the same as three smaller motors. I have seen some videos on YouTube on how to make your own motors, though.</p>
<p>It might fly on only one, but it wouldn't go very high. This was a pretty heavy model rocket. </p><p>I could have bumped up to a higher level rocket motor, but I used what I had for this. :)</p>
<p>ok then I will us 3. Thx for the fast reply!</p>
<p>Are you planning to build a rocket like this? That's cool!</p><p>If at all possible (especially if you're new to model rocketry), I'd highly recommend building a lighter rocket and going with a single engine. You'll have a higher chance of success. Just a thought. Good luck! </p>
<p>this is my first scratch build </p>
<p>Hey! </p><p>Can you suggest me any other ways to make the nose cones? perhaps by using Balsa wood?</p>
<p>I made nose cones for scratch-built rockets by gluing a wood dowel into a block of balsa, then putting the dowel into a power drill, which I held in place with a bench vise. Then I used an car exhaust clamp to hold the drill's trigger down and shaped the nose cone with sandpaper. Basically, it was a makeshift lathe, but balsa is too soft to use a chisel on, hence the sandpaper. Wear a dust mask if you do this.</p>
<p>Excellent project! I may probably never be able to build such a rocket myself, but still, you project has inspired me. All the best for the future!</p>
What did you use to make the nose cone template
<p>Hi Preston, </p><p>For the template, I just drew out a shape that looked "nose-cone-ish". That's probably not a lot of help, though! ;)</p><p>To draw a template, start with a rectangle where the distance across the shorter side matches the outside diameter of your rocket body. Then draw a curved shape that you like on one side of the rectangle. That's all I did. Hope that makes sense! </p>
How did you make the nose cone template
<p>ok i've made the first tube with six layers but they have dried while still on the mailing tube, i made sure to not glue or tape the first layer on the tube and it was pretty easy to slide off but after putting the other five layers on I cant seem to get it off, this is my second attempt at doing this please help</p>
<p>Hmm. You may need to just carefully cut that off and start over. The layers immediately begin to shrink as the glue dries, so it's really important to remove the new tube right after you make it and have it dry <em>off</em> of the forming tube.</p>
<p>how long did it take you from start to finish </p>
<p>I really don't remember, but I'm guessing about 10 hours total.</p>
<p>And Where did you get most of your supplies </p>
<p>I occasionally buy rocket supplies from this place: <a href="http://www.apogeerockets.com/" target="_blank">http://www.apogeerockets.com/</a></p>
<p>Did you use spray paint or just use regular paint</p>
<p>I used spray paint for this. See step 9 for details. </p>
<p>About how wide are the fins and also how did you connect the nose to the rocket? Thanks!</p>
<p>Hi!</p><p>The fins were about 5 inches wide, from the body of the rocket to outside edge of the fins. The leading edge of the fins were about 6 inches long.</p><p>The nose cone sits inside the top part of the body tube.. See step 7, photo 2. You can see a bit of a lip where the cone gets wider, so it can't slip into the tube past that lip.</p><p>Hope that helps! Are you making a homemade model rocket?</p>
Wow thx for such a fast reply! Yes I'm building a homemade rocket. <br> How do you connect the parachute to the rocket?
<p>There is a "shock cord" (for this rocket, I believe I used a piece of 1/4 sewing elastic that was about 3 feet long) that is tied to the bottom of the nose cone, and glued into the body tube. The parachute is tied to this cord about 3/4 the way up from the body tube.</p><p>If you're new to basic model rocketry, there's loads of info online to help you out . . . I don't want to deter your effort of course, but you might want to start by building a couple of kit rockets first! :)</p><p>Here's a <a href="" target="_blank">classic rocket kit </a>available on amazon. Starting with a basic kit like this one will teach you a lot, so when you do jump to building your own rocket from scratch you'll have the skills you need. </p>
<p>I have a lot of model rocket kits but not on this scale and have never done a scratch build. Thanks once again! </p>

Really very nice!! :)
I'm buying my gopro today and am going to make this. Did you use recovery wading? If so was it below or above the camera? As I build I might come back to ask more but right now that's my only question! And good instructable. Really cool.
<p>Thanks! I put wadding on top of the camera carriage area, just to protect the parachute (the camera is completely sealed off from the inside of the tube.) This is a project I've wanted to revisit, but I just haven't had time. So I'm excited to see how yours turns out.</p><p>Good luck on it! I'm happy to try to help if I can.</p>
How did you ignite all three or two rocket engines at once. Also how did your nose cone blow out if your camera mount was in the body above the engines
<p>Ah, I didn't explain that at all, did I? My apologies! </p><p>If you look at my bullet bill rocket project <a href="http://www.instructables.com/id/Bullet-Bill-Rocket/" target="_blank">http://www.instructables.com/id/Bullet-Bill-Rocket/</a>, in step 13 I show the launch controller I use for igniting multiple engines. You can buy a multi-clip harness for hooking up multiple engines, but I just made my own. </p><p>Hopefully that shows what you need to know! :) </p>
Oh I see. Just forget about the nose cone question
Really good job I can't wait to make one we have two go pro's
<p>Thanks! If you make one, I'd love to see how it turns out!</p>
Good idea. The video is really beautiful. I thought it might spin or land face down but it saw everything.
<p>Hey, thanks!</p><p>I've been toying with a newer version of this, but haven't gotten into it yet. Maybe someday! This was a great project, and my kids really enjoyed it. Parents + kids + rockets = fun times!</p>
<p>What fun! Great video!</p>
<p>Love it.... Bookmarked this one for future reference..... :)</p>
Thank you! I've been wanting to revisit this project for a while. Maybe try again and make a lighter version. So many ideas... so few hours in a day!
Definently making this thanks seamstar awesome instructable!! How long did it take you to make ?
Oh boy. I have no idea. It was a while ago. But I'm glad you liked it and are going to try to make one! Good luck!
This looks like a great use of a GoPro! I was wondering how the rocket is internally set up, seeing that the payload is central. I couldn't figure out how you deploy the chute.
Thanks! The chute is deployed when the motors complete the thrust phase, and then have a small explosion on the top end which pops the nose cone off. The camera housing was made to seal the camera off from the rest of the interior of the rocket body, but with a through-hole behind the camera area so the pressure from the backfiring motors can reach the nose cone. Hope that makes sense!
Ok thanks, that clears it up.
What is the internal diameter of the tube, the wieght and the thickness of the cardboard ? <br/>I'm making a rocket that is 30 inches tall with a diameter of 10.5 mm. <br/>But it's pretty heavy. <br/>I was also wondering if I could use c engines instead of e
And maybe a new GoPro Rocket video :)
Can you please make an instructable on how to build a model rocket including where to put the parachute and that kind of things for the very very very noob. <br>(Here is homemade solid state rocket fuel very cheap but very good http://www.youtube.com/watch?v=yUYxk-y-tU8)
You haven't put any weight in the nose? How does it look for stability?
