I will be there. Towing the trailer. I will be there 9:30ish.My van has a 10′ cargo area. I am only going to be using a couplefeet this launch. I will have a small tent heater running if any onewants…   Read more»

WOW! That was an amazing video.

That’s a super cool video, I dream of having a job like those guys. Its videos like these that inspire me to make my rockets work properly and to document them.Although it’s just from one angle and not th best…   Read more»

Now, that’s a rocket! Sean, that is SWEEEEET!

page 8.

Sean, what page was the rocket on? I didn’t see it – but I didn’t sort through all 142 pages of photos 🙂 Congrats!

I lay up all the tip to tip for a given layer at once – sometimes 2 or 3 layers on each even now that I’ve got the procedure dialed in.Picture a 3FNC bird – number the fins 1, 2,…   Read more»

Hey Warren, (a.k.a tip to tip master)In your pictures it appears you lay all 3 valleys of fins with fabric at the same time, then bag the whole fin can, is that correct?I have been doing one valley at a…   Read more»

This was obviously NOT an optimized design, but a platform to test a variety of things and given a few “experiences” during the years leading up to my L3, I wanted something that would survive a fall from significant altitude….   Read more»

Wow – impressive build, and I hadn’t realized that you had that much fabric on the fins. I should drag race you sometime 😀

Hi everyone,Warren, very nice article on a well built, beautiful bird. Thanks for taking the time and showing some of your tips.

Those U-bolts are there purely for backup in case the eyebolt in the motor closure fails or unscrews itself. I use 1/4″ quicklinks – 1 per U-bolt and I have a short loop of sewn kevlar set up in a…   Read more»

Thanks alot for that great post Warren! Very interesting to see what can be done with a vacuum bagger. What did you use to attach your shock cords to the u-bolts? It looks to tight to use a quicklink without…   Read more»

Bruce,Any comment about hijacking was directed at myself for including a photo of my own rocket in another’s thread. I still like the idea of dual centering rings with two attachment points, but my concern was that I am showing…   Read more»

Ed and all, I didn’t mean to dominate this or any other threads that Bret has posted either. There’s such a diversity of opinions in our club. I just just wanted friends to jump in. Now that they have, I…   Read more»

On the last two rockets I built, I positioned the upper centering ring so that it coincided with the upper rail button. Doubling the thicknes of the centering ring allowed enough material for a threaded insert, which was used to…   Read more»

I could get twice the glue area and filets on the body tube side of the centering ring assembly. I could not filet between the rings where they meets of the motor mount – only on the fore and aft-most…   Read more»

Ed – I like the double centering ring approach for the booster retention u-bolts, but do you think it is stronger than just stacking a pair of rings together? Surface area of the glue joint would be the same and…   Read more»

I built this mostly from the Scotglas components – nosecone, tailcone, and fin set. I bet the finished product is pretty much the same as the Mad Cow version with the exception of the molded fins vs. the MC’s G10…   Read more»
