Today is the Anniversary of two great events.
12 April 1961, Yuri Gagarin became the first man in space.
12 April 1981, STS-1 was the first orbital flight of the Space Shuttle Columbia.
My new Nokia Lumia 1020 was stolen from my work on Friday. I called ATT and reported it stolen and then went to their website to lock the phone. Can someone explain how this works? My new phone was only 8 days old and ATT gave me a new SIM card to put into my old Nokia Lumia 900. So now I have...
I stopped by the Hobby Lobby in San Antonio on Bandera today and found two packs of F15-0 for 32.99, some E16-4 and -6 for 24.99 and some F16-6 and -8 for 27.99.
I was going to get one pack of the F16-6 and use my 40% coupon and decided to go and look thru the clearance section. I found...
As a former flight medic and volunteer fire chief, I can say that he is truly lucky to have survived without head or spinal injuries! My wife and I will pray for him tonight and in the future until he makes a full recovery. Can you tell me his name so that we may include him our prayers? You can...
I have been building and flying rockets for many years and I know what modifications would need to be made to make it flyable. That's why I said "semi-scale". I know it would need an extended body tube up front to keep the cg/cp locations correct. I just like the overall look of the angular body...

I just read this and noticed that this satellite looks like it could easily be made into a flyable stable semi-scale rocket.
Oh by the way........it's supposed to re-enter soon!:hot:
It looks great! I started working on mine again after putting it away for almost 2 years. It will be almost identical to yours except that I am using a 38mm central tube and will have an interchangeable motor mount for either 4 24mm or 1 29mm or 1 38mm motor. I only have the 4 24 mount built so...
Thanks for the comments. I will be adding epoxy fillets to the fins. I have used medium CA initially followed by epoxy fillets for small plywood fins like this and have never had any problems. I use wood glue for balsa fins because they seem to soak it up better than CA. I always cut away the...
I glued the motor mount in after I checked to make sure the motor hook would clear the end of the body tube at max extension. I also cut off the end of the motor hook so it wouldn't burn off during Max Q.:cyclops:
I will have more soon. Thanks for watching.
The fin warping was very minor and it only took very slight pressure to make them straight again. I cut a straight slot in a piece of cardboard and slid it over the fin hoping it would straighten it out but it was still curved. So then I cut a very slightly curved slot in the cardboard and slid...
I carefully shaped the trailing edges of the fins with a disc sander and finished them by hand with a sanding block using 220 and 320 sandpaper. The fins are very good quality birch plywood but they ended up with a very slight warp.
The shipping is very high on that one. Here is one that's a little more reasonable price overall https://www.ebay.com/itm/Estes-Model-Rocket-Saturn-V-Limited-Edition-/110978226036?pt=Model_Kit_US&hash=item19d6d15774
Yes, you could cut off just enough to get to tube thats in better shape. If you cut off more than 1/2 inch though, you might need to add a bit of weight to the nose cone to stay stable. I use thin CA to strengthen body and motor tubes.
I had built an RC high wing 4 ch trainer while in high school and had a few good flights on it. My best friend and his cousin who was in the Navy and about to start flight school came over and I showed it to them. He went nuts over it and wanted to buy it right there. I thought it over for a...
