4" Frenzy XL

Nice work. Your final paint scheme reminds me of an Argent.

Just something I noticed that you probably already took care of ... you're going to clean up the vent band holes with a little sandpaper, right? They have to be perfectly clear.

Thank you! I trying a bunch of new techniques with this one that I've seen around on the Internet. So far everything is going as planned and I should be ready to fly it in the next couple of days.

The vent holes will be cleaned up, they haven't yet.

Currently working on the external fillets. I'm waiting for the second set to cure enough to not run when I rotate to do the last set.

I also started thinking about how much time I have left to build. Currently it's Wednesday evening and its planned to make its first two flights this Saturday. I still have to finish the external fillets (should be done tonight), carbon T2T, paint, and finish the av-bay. Based on this, I've already decided that painting and decals will be done at a later date (it's about a month to the next launch) as well as the T2T. So for now, it will be built to be ready to fly.

The more I think about this build and the new techniques I'm using, the more confident I am in its capability to survive the burn of even a 75mm 6XL motor for an EASY L3 cert. but that's just not the direction I want to go with an L3 cert. Sure when I do get an L3 I'll stick a really big and stupid motor in it someday, but just not now.

Edit: Please don't take this post the wrong way, I'm not trying to bash on anyone who has gotten their L3. I'm just thinking. About it since this rocket is set up with everything you need to accomplish such a task. Redundant Av-bay, 75mm motor mount, really strong, documented build...

I love key switches. They look cool, and they make it easy to turn on your electronics. Not to mention the cool 'Remove Before Flight' tag that completes the look:

Also an update on the build/flight schedule for this rocket. Due to the launch date being changed to this Sunday, I will not get this airborne until December 19th. I'm still going to the launch, but only for a little bit as I have plans for later in the day. Therefore I will make one flight (Punisher on CTI K740 C-star), recover and head home. This gives me the opportunity to slow down, get T2T done and paint this rocket in time for its first flight. I'll keep on posting as the build progresses and I attempt my first T2T.

I have  been  following and it is good to do the T2T now before the first flight.
Agree with your thoughts about L3.

Good build...nice pictures..clear thread to follow and I am looking forward to the T2T...prob the paint job also and an interesting December flight.

Thanks for sharing the project.

I agree it is good to get the T2T done before first flight. I just really wanted to get that L motor airborne so I can scratch it off my bucket list, then move onto a skidmark in the same case for the December launch. However, it will end up being the L910 in December. I'll get a skidmark up in either my punisher or 54mm MD (J145 long burn Big Grin)

Thanks for the comments Tom, and your welcome for sharing.

Just got done laying up the first set of T2T.

[Image: attachment.php?aid=777]

This is my first T2T job, carbon or fiberglass. So far I think it's going well. Going to get started on the next set soon.

Spent a bit of the day today at the MMMSC launch in Berwick, ME. Brought this rocket up to show, got a lot of Ooos and Ahhhs out of it. But my main attraction for going was flying my Punisher on a K740 C-star. That flight also got a lot of people going Ooooo and Holy $&!+. Got 9,942' out of it, I'll probably post video later.

Now that I found myself some time to do it, I edited and uploaded the video of the Punisher. 240fps at 720p and Mach 1.5, enjoy.

Also spent the last couple of days cleaning up my workshop (still in progress) but I found time to clean the fins of the Frenzy. I trimmed the edges some more as well as adding another layer of epoxy to get a smoother surface and better shine.

Also ordered a decal from Mark at Stickershock. He used a photo of my carbon T2T to get the decal created exactly as I wanted it, thanks Mark!

Started masking off parts of the carbon in preparation for sanding for primer. Probably will get the first few coats on tomorrow if it's not too cold out.
