Here is a link of a fellow who at the time had set the world record for flying the largest model rocket. This was back in 2009. It makes mine look like an Estes toy.

That thing is awesome. They must have used a tractor trailer to get everything there. Wow that is big. One thing I always thought is that these models were a two stage rocket. It was incredible how the booster stage came down and landed upright causing no damage at all to itself That was really impressive. Thank you for sending me that!

To my knowledge, the models regardless of their size have all been single stage. They do not accurately depict the actual staging of the real Saturn V which possessed three stages. A whole different ball park as far as technology for the amatuer rocketeer. There is already in the works rocket motors that actually gimbal or pivot as the real F1 engines did. While you may not notice the engines move themselves during lift off, you can see the effects during initial launch where the rocket moves away from the tower at an angle to avoid a strike. There are videos showing ground tests of these F1 engines gimbaling inside the test stand.
I would start at 7:27 to watch the gimbal effect.

Those are some powerful engines. I have seen the engines move a little. I wasn't sure if they actually pivoted for guidance or because of such a boost effect moving them. Now I know that they actually pivot on a gimbal for guidance which is a new thing I learned today. Thanks for the info. You are definitely amazing on your knowledge on the facts of the Saturn V Rocket. You have definitely done your homework on this subject.

That model was on display in Huntsville during the 50th anniversary; very cool rocket.

AND... wish I'd have been around to watch those F1's

My dad who was a flight engineer for AA took my younger brother of 8 while I was 10 down to the Cape to watch the liftoff of Apollo 11. I was absolutely blown away as a kid. I could not possibly imagine the raw power coming from this flaming candle. I had seen some WWII movies at the time believing this was going to sound similar to all the racket going on in the movies. Wrong. I still remember how my insides kept shaking at a rapid rate to the point where I asked my dad if everything was alright. He reassured me so. I'm proud even as a kid to have watched a part of history being made that today so many dismiss as conspiracy. I understand what I witnessed was not 'proof' itself yet I also understood it was a race between two countries on who would get there first. One country won and never challenged the other after the fact.

Thank you. I've got two coats of gloss white on the third stage and aft interstage section. The SLA and upwards has yet to see any gloss white. They're still only in primer. Sanding with 400-600 wet is next. Nothing really to show here. Not until I start adding the gloss black and aluminum to the aft interstage, IU and SM will I post more photos.

that looks like about a 9" motor. This is the first time that I have ever seen a reloadable motor. Definitely cool. I have always used disposable motors in all my rockets. Never got quite that large!

Good assessment, 9.75" in fact. 54 mm. in dia. These are Reloadable Motor Systems. Here is a link for buying the reload kit: https://www.apogeerockets.com/Rocket...A?cPath=7_267&
Once used, you clean out the casing with white vinegar and a wire brush of the appropriate dia. (gun brush or automotive brush). Then wipe clean with a cleansing wipe and dry with a clean rag or towel. It actually costs less to have the consumer assemble the motor as opposed to the manufacturer to keep the cost down. So I will be using a J275-W reload for flights and experiment with others depending on the overall weight of the rocket when using larger motors.

Sometime during my visits at Starbucks I had a two week episode of depression. One of the customers took it upon herself to obtain and have others sign this for me.
What more can I say?

Due to over zealous sanding I removed a fair amount of the pin striping tape from the systems tunnels. I have reapplied more tape and will shoot this with gloss white.

i admire your attention to detail and perseverance.
i'm at the other end of the spectrum, learning to build cheap foam airplanes.

I've got a Don Smith B-17G as a partial build. Been laying around for 15 plus years untouched. If that's not a hangar queen.....

what makes you stop before finishing? i'm in the middle of building a yak, my 3rd foamy. sometimes i wonder if something is taking too long, or something prettier comes along, would i put it aside?
i do have a couple of balsa builds under my belt from 25 years ago.

I don't really remember. I'd say lack of interest. Still have it, just sitting around collecting dust.

https://www.turbosquid.com/3d-models...d-model/462519 This is a must see site for Apollo subject matter. Using this I may very well duplicate the EVA handles on the SM. I even possess the intricate decals to place on the SM. Very delicate, intricate detail to be found for modeling something of this magnitude. Info is out there along with the David Weeks drawings I bought. Knowledge is power and this information will help tremendously in taking detailing to a new level. I'm very excited about this new find.

This is a close up image of the SM. I've ordered the EVA handles from Shapeways. Michael made the rails a bit on the beefy side to help ensure the integrity of these pieces during shipping.
