Hi all,

I just wanted to post a thread here about my motor mount conversion for my first "big" rocket, Big Red. Why do we call it Big Red? It's kinda obvious! It's big, and it's red! For those of you that don't know the story, which is probably most of you, here it is.

Sorry I haven't updated this thread. Here's more of the story:

Since it was close to my birthday, I had been doing research into clubs in Florida. Well, I found a couple, and picked NEFAR as the one I wanted to go to since they seemed to have what I would need to fly this rocket. Remember, I was clueless into what exactly I would be needing to fly this big ol' rocket at the time. I did some more research into the motors I would need. Since I didn't know that Estes had stopped producing the Darkstar motors, and those were the only two motors recommended for this rocket (the F62-4 and the G75-6), I did some more research, and found that there was another company making F motors similar to the F62. This company's name was Aerotech. I found a vendor that carried these motors, and then my neighbor and friend Kevin surprised me. He told me that since it was so close to my birthday that he would order these motors for me! I was like, "WOW...". Well, being as clueless as I was then, told him that I wanted the F50-4T for this rocket's first flight. I told him I wasn't sure if this motor would be OK since the 'T' stood for a mini-motor....

He ordered me three of these motors for me for my birthday. Oh, I forgot to mention that I had bought an AT HV Arcas off eBay using my Christmas money for that year, and had built it and painted it - that was fun!

Anyways, the motors came and my parents told me that we would go out to NEFAR for my birthday. It's since then become a tradition that we would go to a club meet for my birthday.

I wasn't sure what to pack since I was so darned excited! So, I packed everything! I took my controller and pad thinking, "Well, maybe they'll need another controller and pad." Come to realize, I wouldn't need any of this stuff, so I felt kinda silly when I got there. I received the motors in the mail, and immediately I tried to put the motor in the MMT, just to see how it would look! Uh oh! The motor doesn't fit! OH NO! I found out that the F50 was just a tad bigger than the MMT! So, I started sanding...and sanding...and sanding some more...! It was insane, but I finally got it to fit in the MMT. I told myself that I would only fly this rocket once because I wasn't sure if the F50 would lift it because it was a "smaller" motor that the F62. See? I was totally clueless about MPR.

The day finally came to go out to NEFAR! I invited my friend Mike, and we all piled into our little Dodge Caravan with all my stuff for the ride out to Bunnell (the town closest to NEFAR) at 5 am!! We finally got out to the field at about 9 am and we started setting up shop. I then saw that NEFAR had every one of the pads that I would possibly need, plus more, so I felt kinda silly. I decided that I would fly some of the LPR rockets first. So I did. I flew my little Alpha and my Big Daddy, and they flew great! I then finally decided that I would fly the Phantom, which by that time we had dubbed "Big Red," since it was big, and it was red!

"And that was a textbook flight, ladies and gentlemen!"

He was right. The flight was perfect in every way, and the day still lives in my memory as the day that I swore to myself I would never give up rocketry again!

What a story Jason! I like the sarcasm you used throughout the story . When is your first G motor? My first G motor was a G64 in my Phantom 4000. Can you guess what happened with that flight?

Your story reminds me of my first MP flight. I was at a small feild with my club, we were hosting an even called "Space Day" I overheard someone offering someone else a motor, a became interested and walked over, the man said he would sell me the motor, an E15 which I immediatly realized was too small for my barracudas 29mm mount. I walked over to the club presidents truck, and asked him what he could do for me, he gave me an adapter tube, and after alot of taping, I was in line to the pads.

The rocket lifted off slowly under white lightening power, kicking up lots of smoke and, in the small feild the motor roared. The motor opened right at apogee, what a flight, when I came back with the peices the local telivision station interviewed me and I was on TV! It was pretty awesome, I was only 11 and I had launched a huge rocket. Well, for that feild, and what I had seen of rockets it was huge, but I would soon come to realize that there was much more out there, and from that day on I became obsessed.

Sorry guys - no more story right now, but here are some pics!

I have been working a lot at my job, getting used to it and all, then studying for my math test and all that good stuff, then finally I've gotten a chance to work on Big Red!

I did some easy epoxy fillets and fiberglassed the entire fin can area on the exterior. Now I am in the midst of filling and sanding - it's pretty easy though. I should have a coat of primer on her this weekend!

Here's the pix!

And another pic!

Alright, I might as well update this thread, even though it has nothing to do with what I was searching for...LOL.

I finished the mods you saw in the above pictures, and gave it to our local club's automotive paint guru, Joe (lets fly high), and had him paint it for me. He did an absolutely EXCELLENT job, and I just have to show it off! It is PERFECT!

You need to take that rocket out into the sunlight and take some better shots of it. Those pictures DO NOT do it justice!
