HERE after about a dozen launcher our luck ran out as the wind got up an blew the bloomin rocket into the trees so to get it down we went out with airguns an shot it down from the trees but then that was the end of that rocket but made up others an flew them all through the summer an we had a great time an all our freinds came down to the lanches an we had BBQ an made a lovely evenins of doin this an the kids got really excited any way steven hope you like our times in this hobby as we all enjoyed it an thank you for allowin me to post the pics in your thread

Hi Steven, great looking project you have.
Superb that the interactions in your Starbucks helped you along, would be pretty cool sight to see happening when one just entered to order coffee and sees a massive rocket being built:thumb2:

[boatman]

HI again Steven been looking through your build again an i wondered what size engine will she have if she's gonna fly will it be a D engine or some thing bigger as for us in the uk the D ENGINE was the biggest you could get but it only had about a 3 second burn time but still hit over a 1000 ft up as we were goin to buy some untill we found out the cost an we had to be carefull as we had RAF JAGUARS flyin over our heads at times an if they were about then no launches with our rockets

I had two occasions where a customer only saw the drawing and bits and pieces on the table and started asking questions. It was in the middle of this when I saw them actually set their eyes on the 7.5 foot stack and their jaws literally dropped. I believe their peripheral may have made the rocket seem like part of the building structure rather than an actual model. I couldn't help but laugh out loud.

This will fly on a Reloadable Motor System. I have an aluminum casing with aluminum screw on end closures. The engine I will use is a J275W. The casing is 54 mm in diameter and 279 mm in length. The reload is about $90.00 per flight. I also need to be certified level 2 by an NAR club to purchase one of these. Love your flights of once upon a time Christopher. Takes me back to the 70's doing the same thing.

Hi again Steven is the fuel solid propellent or a liquid ? an is it eletric egnited ?

The reload kit comes with solid propellent grains, graphite nozzle, delay charge, ejection charge, assorted rubber 'O' rings and spacers plus an igniter.

Apogee Components also sells a 1/70th flying version of the Saturn V and Saturn 1b.

Both of which I possess. Also the original Estes K36 Saturn V along with a Centuri Saturn V and Saturn 1b.

YES Steven i see what you mean about this engine what a cracker just what we could have done with but just before we packed up building our rockets my last one was made out of a 4 " carpet tube about 4 an half feet long an i lined the tube out with metal foil to protect against the heat from my engines as i fitted in it 5 X C-65 ENGINES an it took me about a month to build an when it was finished we took it out to launch an luanch it did but it was not a sucssess as only 3 engines fired an it only went up about a hundred feet an at the cost of this we gave up an if i remember rightly thats when i started to build my big R/C WARSHIPS that im still doin but i'll always remember the rockets with fondness an excitment an now im looking forward to seeing yours built

Did you use a 12 volt source for ignition?

[boatman]

Did you use a 12 volt source for ignition?

NO it was a 6v source for ignition as i said our rockets wernt as big as yours an 6v did the job most times like i said above sometimes they mifired an we had to stay back for a little while to be sure an safe that when we went to it wont fire up an hit us an nice talkin to you Steven will talk again tomorrow as its now bed time an my missus is calling me to bed good night

12 volt systems have been highly recommended for cluster ignition whether for two, three, four or more. I don't know what the limit is on how many engines can be lit successfully on 12 volts. Clustering takes more voltage to light two or more igniters. The standard 6 volt system doesn't possess the voltage necessary to light more than one engine. I found out the hard way myself as a kid using a 6 volt system to ignite a two engine Centuri 1/100th scale Saturn 1b and a three engine cluster in my 1/45th scale Centuri Little Joe II. Not all the engines lit and when the ejection charge went off, it lit the remaining engines backwards throwing flames out the other end on the ground. Caught the desert on fire which my dad and I frantically put out with our shirts.
Fun times.
