Ok so I didn't plan to buy this rocket, but it was on my wish list and my local store just happened to get one in and I couldn't pass it up. When I decided to get back into the hobby I wanted to make sure I didn't go crazy and just buy every rocket that looked cool. So I made the decision to buy one rocket for each of the engine sizes, based on the rockets smallest engine. This meant buying six rockets for the following engines. 1/2A, regular A, regular B, large C, large D, and Pro Series E.
This one is the large D engine, I already have the others.

My first rocket build I had already started building when I decided to do the diary. I also wasn't sure if anyone would enjoy the build or not. Now that I know there is interest, I will be doing this from the beginning starting with a photo catalog of all the individual parts. If you have questions about any of the steps or parts you see feel free to ask.

Ok made some progress. So I will give info on what I did followed by photos. Let me know if you guys like this style of posting.


First thing to do was mark up the engine mount tube. You are supposed to use a ruler/tape measure, but I find that this can be inaccurate due to human error at times. So for the part that required more accuracy I marked based on the location of the part once installed by doing test fittings.

First I made the mark for the engine hook using the engine block.



Then I cut the slit for the engine hook.


Then I test fit the engine tube into the lower body assembly that I also had test fit together.



Then I measured for the location of the engine hook retainer. This part didn't need to be as precise.


Then I installed the engine hook


Next up the engine hook retainer


After that the lower adapter ring


Finally the engine block.



While I left those parts to dry I moved onto the lower body section of the rocket.

First I glued the small body tube and lower body ring together.



Then I attached the fins to the lower body tube and ring.






Last I glued the upper body ring to the lower body tube and fins.



That's it for tonight. I am going to let the glue dry on both of these parts and then its time to install the engine mount inside the lower tube.

One other last thing I did, while test fitting the engine tube parts, I noticed that the upper adapter ring was very tight and hard to get on the tube. It was starting to cause damage to the tube while I was trying to test fit it. So I took a file and filed an angle relief on the inside of the ring.


It now slides on much better now.

Ok some more progress.

First thing is to install the engine mount assembly into the lower rocket body. Make sure you test fit first. I had test fitted previously without all the parts assembled and I put down a layer of glue only to find out I couldn't get the engine mount to go all the way in. Had to do some rush adjustments.




Next up is to glue the upper adapter ring onto the top of the engine mount.




Then its time to glue the upper body tube to the lower rocket assembly




While that's drying its onto the nose cone. First thing to do is remove the excess plastic inside the parachute loop.





Now to attach the parachute. First you thread the end of the parachute lines through the parachute hoop on the nose cone.




Then you thread the parachute through the end of the parachute lines and pull snug.




Finally for this post will be to make the shock cord mount.
First you cut the shock cord mount to the right shape.




Then you glue the shock cord and mount together.







Last step for shock cord mount is to shape it into a curve and hold between fingers until it dries

Ok next up is to glue the shock cord inside the body tube. The instructions will tell you have far down inside it needs to be glue. As long as its below the bottom of the nose cone you are good. Make sure that the entire shock cord mount is glued down to the tube. This is the main stress point on your rocket when the parachute deploys. If its not attached solid it could break loose when the parachute deploys. Its why they have an elastic sock cord as well to take stress off of this point during deployment.




Next up the launch lug/guides. The ones on the EX2 kits are curved to fit the body tube curvature. Make it easier to have a straight line.



What I usually do here is pick a spot near the bottom and glue the first one on.



The I measure the distance that they are supposed to be apart. This doesn't have to be perfect as long as they are a good close. The important parts is that they line up properly when they are on the launch rod. That's why after I measure the distance apart I glue the second one on and use the launch rod to make sure they are lined up.



The only things left to do are to tie the shock cord to the nose cone, which I will do after the mount has dried. Then apply the decals.

Ok so a few days delay on the update since I had uber busy weekend.

Alright so the next thing I did was tie the shock cord to the nose cone.




Next up is to apply the decals. Which I did, but forgot to take photos. Not really gonna take and post any, as there isn't anything special about this step and its optional anyways.

Then I prepped the rocket for launch. First I added the fire resistant wadding.




Then I packed up the parachute.



Then I installed the engine space. This is used when you are flying with D engines but is not needed for E engines. First flight of a rocket is always with the smallest engine on the list.



Now the engine




I tried posting the launch video but its not working. Any suggestions?
