Hi everyone, I don't have much experience with altimeters in the nose cone.... My experience is limited to data recording altimeters only. So, now that I'm putting the altimeters in the nose cone that will control my ejection charges, I have a pretty basic question and want to know how others...

I am trying to find options for a 29mm nose cone. I've made a rocket using Public Missile 29mm motor tube and now need to find a nose cone. I thought it would be easy, but it's not proving to be. So far, I have only found one at Apogee. It's not bad - it's the one that sits atop the apogee...

Hi everyone, Not sure if this has been covered before. If it has, I cannot find the thread. Here's some background: I recently attempted my L2. It was a picture perfect dual deployment. Everything went as it was supposed to go; however, when I went to retrieve my rocket (a 2.75x upscale...

Hi everyone, Not sure if this is an issue or not, but wanted to ask. Is having a Carbon Fiber airframe an issue with the GPS antennae? If so, how does one compensate? Thanks. Don.

Anyone have one?

Hi everyone, Wondering what the epoxy of choice is for high temperature rocket applications. I'm making a motor tube for Mid-power out of Soller Composites Kevlar/Carbon Fiber weave and need something that can stand up to the extra heat. I have used West System with 207 hardner, but I don't...

I'm pretty excited about this. Thanks perfectflite! https://www.perfectflitedirect.com/stratologgercf-altimeter

Hi everyone, So, I picked up a 4/5.5 Honest John at Madcow's black friday sale (i know, i'm a little behind on projects). My 11 year old daughter and I are going to work on putting this thing together. We want to make it dual deployment and I wanted to see if anyone else out there had tackled...

Hi everyone, let me start this off by saying I'm not an electronics wiz by any stretch of the imagination. I'm trying to wire up some LED lights and hook up to the 3 pin Audio connector port on the stratologger. I'm not sure where to even start. I appreciate any help the group can offer.

Hi everyone, I'm contemplating a build that needs to be super light weight and have somehow justified using carbon fiber in my mind. What are the best sources out there to order tubes, including couplers, and plate material from?

I saw these all over ebay several months ago, but not anymore. Does anyone know where I might get these? I think it was a cluster of 5 motors. Appreciate the help. Thanks.

Wondering if anyone has attempted to design build the 10 motor Falcon 9 or the 28 motor Falcon Heavy? Thinking this would be really cool to see with all of the motors clustered together. 24mm's would probably be a bit crazy, but 18mm with C-6s might be do-able.

hi guys, I recently reinforced a cardboard body tube with a layer of fiberglass and carbon fiber. Looks really nice. the West System Epoxy did marvelous, as I finish this, what is the best clear coat to apply? I want something that is crystal clear and not foggy. I want to leave it so that...

wow. this might be old news, but I just stocked up!

BT80 tubes seem to have lots of options. not so much for the BT70. Balsa machining has lots of balsa nose cones for the BT70, but I want plastic for its durability. Anyone have any recommendations?

Hi everyone, looking for a bit of advice. The best place to put my altimeter is in the nose cone, or close to it. how far back from the shoulder should the vent holes be so as to get a good reading (or conversely, not get a bad reading). Thanks.

I need to use the ejection charge from the rocket motor, so the internal motor mounts are not an option. Any opinions about Slimlines? I've only ever used the Aeropack retainers, which are great, but not necessarily minimum diameter. Thanks!

they always seize up on me and I end up throwing away most of the contents. Anyone have recommendations for replacement bottles?

Hi everyone, I'm in the final stages of a scratch built level 1 rocket. It is 5.5" diameter and 50" long. I expect it will weigh somewhere around 8lbs when it is launch ready. My question for the group is around the shock cord. I have 5/8" diameter nylon cord and I was planning on 3x the...

Hi everyone, I'm trying to find out if anyone has some good ideas for connecting all rocket components together- i..e. the nose cone, parachute, nomax, ebay, swivels, etc. I think putting loops in the shock cord should be easy, but every time i do this, I end up with a tangled mess. I was...
