Scratch designed and built 5 inch diameter 10.5ft tall. Flies on anything from a big L to a baby O. Flown 6 times thus far. Consolidated writeup and flight log : https://www.dropbox.com/s/7iejwpalpbm9kbz/versodone.pdf?dl=0 FB album (please do not friend request me) ...

I see youve put a lot of thught into the structural integrity of the IST itself, good, but what about the coupler holding it into the booster airframe, and the length of motor youre using on your sustainer into it? We've seen quite a few full stack (with full weight) tests prove that even a...

Wow this thread inflated like a balloon. Interesting to see so many people have had issues with him as well. A few key questions have been asked over and over and kinda/sorta answered by various people here and I will take a stab at them as well 1- Most rocketeers are also forum users, so why...

Robert Ormerod? https://www.facebook.com/robert.ormerod?fref=ts I think thats who youre after. Also, kinda late to the party here but here is my album from this balls for who havent seen it :) -...

Hello all, hope youve had a wondeful flying season. I sure did, except for the fact that Red Arrow Hobbies decided to keep $600 worth of my money I couldve used to buy more motors, or pay more bills and such, you know, a few bucks... Its been nearly two months, and i never got a penny back from...

Hey all! I will be bringing a 5" scratch build to fly on a couple of commercial loads, one being the N3300 and the other the M1315. Its a 34lb rocket and uses 1515s. Any chance anyone might have a pad/rail setup 12 feet long or better that I could fly off of? I would greatly appreciate it! :)...

I'll be there with a good bunch of cool stuff. Provided Friday evening is still and nice, i'll send up my 5" on an M2500T, followed by an M750W in a minimum diameter the next morning lifting multiple 1080 cameras. (Remember that coupler you made me, James? :) ) We have a K805G to burn and an...

So my plastics man and I made some prototype sled and avbay parts for initial testing and playing with. And we did quite a review of the parts and minor things do need to be changed before they could be regarded as flightworthy, but nothing major. Going to be doing some talking with my GPS guy...

WOW sweet you just basically smoothed out all of my thoughts I wasnt sure about. So I WONT loose lock, and I should see some reliable and some unreliable packets on the way up and down for the areas below 1000kts. Thats good. I will even be able to tell if the rocket is coming in hot based on...

WOW this is awesome! Very pretty rocket! Even the less than perfect flight was still badass 30K aint bad. So a 12 second apogee delay from apogee 'detection' , right? Was this to ensure that they fired on the way down no matter what? I had planned to do the same thing on a two stage of mine...

Yes, you can easily light the sustainer from electronics that are located in the booster/ interstage coupler. Most Estes two stage rockets use this design because the black powder "ejection charge" also serves as sustainer motor ignition, and several high power rockets ive seen use blast...

Yes! Definitely. I'd like to spend a solid week and create a killer ass video for it, I have atleast a few cool clips i might be able to incorporate ;) Now that the rocket is in for review, the next step is to set up said funding avenue, so ill be able to devote my focus exclusively to that...

Ah yes, i think this is the one I mightve been referring to, but got the names mixed up. I will change this today. Thanks! Dont debate this was then the first technically Min Dia or flying case N5800, hitting mid 50s at 100 inches long (LOL) . I think Nic's was the first all composite one...

Evening everyone! I must first apologize for the long delay of progress on the project - I am having a hell of a time balancing school, work and rocketry, and I needed to get an L3 before TRA would take me seriously. Tonight though, I am excited to announce that Project Blacksky is once again on...

Yep Mark I think you are exactly right. It appears that the RMS hardware geometry does the job of the nozzle holder and retaining ring combined, so therefore if the nozzle has the geometry to exclude the holder, the RMS hardware now has extra geometry. Makes total sense. So we were all right...

Hey guys. I was the one that tried to fly the M3400 in the 10240 and nope, it does NOT fit. A couple things- A. The nozzle carrier is omitted by the fact that the nozzle has a larger "shoulder" area. It doesn't actually change the length of the component. B. You are NOT allowed to remove the...

Hello everyone! I am excited to share with you the report of Curt Von Delius' amazing two stage flight at XPRS. He considers this flight a successful test to prove the airframe for future flights of larger impulse in the same stack. Recently he published a sort of 'press release' and suggested...

Wow what an event! We showed up on thursday afternoon and there was already two, starting on three rows.. not to mention the beautiful sunset. I mean, we were followed in by an Lp640 that tailed us for like 7 miles, and then blew by me going into 3rd. It was amazing. I guess you could say the...

Hey guys! Indeed XPRS and BALLS are closing in on me, but I do not plan to fly this year afterall. The design is very close to build-ready but I still need to iron out some avbay workings and I want to take a close look again at the tail with new scrutiny- I am beginning to loose faith in John's...
