Thanks. Here's a pic of the NC shoulder detail. The NC has a 4" dia tube running through it that will contain the 6lbs of ballast.116254

Thought I'd post a pic of the test fit of the "Zeitgeist Maschine", my L3 V2 project. 10' tall, 12.25" diameter and around 90lbs loaded with an M2400. NC and tailcone were fabricated with pink foam...

Thanks for everyone's response. The Adepts don't have an apogee delay. Main Adept measured 1686, back up measured 1712. I would assume this means they both didn't fire at the same time, and it...

I flew a large rocket yesterday on a K1275, and the NC and 10' main ejected at the same time as the booster and drogue. The technical detais are as follows. Dual deploy with redundant electronics (2...

I appreciate everyone weighing in on this topic. Rocket is 8" dia, 9' tall and 34 lbs loaded. Will fly on an AT K1275. Did ground testing this weekend and have the apogee charge dialed in. I've...

I've been using the Quests with the Adept22--no mishaps.

Thanks Mike, I've been using nothing but the Quests, and have had no failures.

Been reading some of the archived posts, but still have some questions about redundancy with apogee charges. Have a large build and I need to use two altimeters. I have two Adept22's-- I'll set...

Thanks for the feedback. If I go with 3 port holes spaced 120 degrees apart, one of them will be on the center of the hatch. As the hatch is removable, and held in place with hex nuts, arming isn't...

I'm finishing a dual deploy 7.5" diameter rocket. The AV bay is accessed via a hatch, and my calculations indicate 3 static port holes .25" diameter. I've read several posts that say the port holes...

Dave (Red Arrow Hobbies) is a great guy and I've never had any issues ordering from him. Very reputable, helpful and attends many launches. I highly recommend him.

I'm going to be in Cleveland over the Thanksgiving Holiday and I'm wondering what rocketry shops/vendors are in the area that might have HPR supplies. Any help would be appreciated.

The Bauhaus 1 is my prep project for designing my Level 3 Cert Rocket. It's 108" tall and about 34 lbs fully loaded with an AT K-1275. The MMT is 75mm; the 1275 is a 54mm motor-it will take it to...

He said he was a bad influence.:dark: After I looked at the Hypertek and Rattworks gear I got really interested. We'll probably make the trip to Jackson, MI (after we fly the Bauhaus) and spend...

Will post rocksim file as soon as I get home. Gotta admit, the fins ain't pretty. BTW, someone suggested a 3X upscale-- we've been giving that some serious consideration, as well as looking at a...

Well, it was a great maiden flight for the Black Widow yesterday at 3 Oaks, Michigan. 21 out of 24 C6-0's lit, and the I-300 went off perfectly with a thermite igniter. We flashed the C6-0's using...

It's 67" tall about 7.5 lbs fully loaded. 2" dia BT. One of my club mates fabricates thermite igniters and suggested it for this launch. My original intent was to just go with the AT...

Thanks! Completed ground testing this weekend and hoping for calm skies next Sunday.

After my son saw Boris Katan's Toginator awhile back, he started drawing designs for his own version (he's only 8). Well, after a lot of rocksim trial and error, we built the Black Widow. It has 24...

My son and I built something similar with a central I-245 and 3 outboard F-20's. It was based on a "rocket lamp" from American Science and Supply that had 3 outboard pods that we modified to accept...

I've been looking at doing the same thing with a 7.5" LOC V2. My plan is to keep my e-bay as short as possible and separate at the top of the boatail. My BT is approx. 30" long, and accounting for...

I know others have posted on problems with Xavien, but I tend to give vendors the benefit of the doubt before coming to the conclusion that they provide a poor service. However, the problems I've...
