Just bought a MAC Performance 3" black fly rocket with the standard Pinnacle nose cone as well as a nose cone av. bay. Everything is just about assembled except for the av bay in the nose cone. I am curious about nose weight for this rocket. The instructions state that CP is 26.3". I have...

I'm selling my Missile Works RTX GPS Navigation system which includes the printed case and LCD screen. Flown 5 times and has always brought me right to the rocket. LCD screen displays GPS coordinates and provides arrows to lead you right to your rocket. Asking $315 for everything. Payment via...

Quick question from those people who use the featherweight GPS system. I could not find the answer in the manual or elsewhere so I thought I would ask here. I know the system provides the GPS coordinates of the rocket, but does it automatically transfer that information to a map app or does the...

I am looking for a nozzle for the AMW 54-1750 motor. I have an old K555SK that I am using for a memorial launch for my father-in-law who just passed. If anyone has a nozzle for sale or that I might be able to borrow in the next few months, that would be great! I fly with MDRA and will likely do...

Ok. Stupid question. I’ve been using AeroPac retainers for years. I just got another one and there is a silver ring included that is about 1/2 inch in width. I thought it might be a spacer for thinner motor tubes but it does not fit in the end that is glued on the mount. It does fit on the aft...

So I have an E-Z Up Jamboree that I've had for several years and I recent just moved. I tried to set up the tent and noticed two of the outer trusses were bent (damn movers). Needless to say, the tent will not open. I tried calling E-Z Up to get replacement parts and guess what...that model is...

I have seen many people assemby their eggtimer LCD with an external switch and push button. I went to digikey and looked them up, but there were thousands to choose from and I am totally clueless on what I need. Can someone provide the part numbers they used or recommend an appropriate rocker...

I built an Eggtimer Quantum and was testing my new e-matches with it and I noticed that the ASL reading on my phone is registering -263 feet. I know my real ASL is around 70 feet. Does anyone think this is an issue or is it ok to fly it. I'm worried that the Quantum may arm too high or the main...

OK, I assembled an eggtimer Quark and when I start it up, I get a single beep and then 3 sets of 10 beeps. I also tested the Quark with ematches and they fired so I think everything is working correctly. When I put it in my ebay and connect up ematches and turn it on, I get a single beep...

Anyone heard anything yet about the fall 2015 Red Glare? Since it is October already, I am assuming it will likely happen in November. Too bad as it is much better when it occurs before daylight savings time ends!

I bought the Wildman V2 rocket at Red Glare. I have finished building the rocket and was wondering how much nose weight (if any) people are adding to the rocket. I have simmed the rocket and I am getting the CP to be at the front of the fins. Based on the sim, I would need to add about 4 oz of...

Got the Interceptor from Wildmans during the Black Saturday Sale. I am close to getting this put together. I do have one question for anyone who has built one. I just put a rocksim together for the rocket and it shows unstable with a small 38mm motor. Is nose weight needed for this? Not sure if...

Ok, got a question for the people who have a 2 stage wildman junior kit (mine is a shape shifter). I am dry fitting the booster motor mount and interstage coupler together. The motor mount has an aeropac retainer on it. The fit is very good when they go together. However, when I put in a motor...

OK, I got a quick question for all of those who have a wildman shape shifter jr. I'm getting close to putting the fins on and noticed that the fin tabs appear to be too long. The tabs put the fins about 1/8" above where I think they should go (the curve of the fin does not end at the body tube...

I have a raven 2 and love it. I was going through some of the data and decided to look at the battery voltage. I noticed that right before liftoff (or maybe right at liftoff), the battery voltage goes to 0 volts for 0.1 seconds and then comes back. At first I though it might be my battery (NiMH...

Anyone have a rocsim file for the mini darkstar? Thanks!

Ok, got a 5" jart for Christmas and I am just about done with the fin can (putting on final fillets). I want to make it DD, and had a couple thoughts. One is to use a tether system, but I would need to buy one. Another option is to use a shoot cannon in the nose cone with an altimeter at the...

I have a 4" Darkstar DD and was wondering what size threaded rod I should use. I have #10-24 rod, but was not sure if it is sufficient for a rocket that will end up around 10 - 12 pounds? Thanks.

Just got a Darkstar for Christmas and was wondering what size chute people have been using? Thanks!

I need to mask some areas on my rocket that have curves. Is there a product that can be used for masking around curves. I know body shops can do it, but I do not know what the product is called or where to get some. Anyone have any information?
