    Thanks from APE

    Over the last 10 years (almost to the day) I've designed and machined a few dozen products, filled close to 1200 orders and shipped them worldwide. All of this was done out of my garage in my spare time. I've decided to shut down APE. The simplest explanation is that I don't have the time or...

    Avoiding Krushnic effect from a tail cone by extending a stock nozzle.

    First off, on this build I’ve already modified the case and closures so it will be a research project. I’m planning to use a tail cone on my M2245 MD altitude attempt project. The stock CTI 75mm XL nozzle only extends .84” past the end of the case. I was planning to keep my tail cone to 1.25”...

    Can someone measure the OD of a 38mm DMS motor for me?

    I need to cut a set of adapter rings to put a 38mm AT DMS motor in my 54mm mount. Does anyone have a 38mm DMS motor and a set of calipers? Can you give me the OD of the motor measured at the label? Thanks, Chris

    Insanity Plea: A sub minimum diameter M2245 project.

    I've been working on this project in the background for quite a while. I learned a lot from my M685 flight to 37,789' in September(Wildman Blackhawk 75). This project is will build on the foundation of that project. My number one goal is for the rocket to survive the flight. The secondary goal...

    Do you build your motors and ejection charges at the launch or ahead of time?

    I'm curious to hear what your thoughts are on building motors and ejection charges ahead of time. I've found that the more I get done ahead of time the more I relax and enjoy being at a launch. So, how much pre-prep is too much? For the record I've been at #2 for a couple years. For the...

    Who carries JST extension cables?

    I've been using JST extension cables to wire my lipo batteries to the screw switches and the to the altimeters in my rockets for a while. I bought a few from SparkFun last year but they no longer carry them. I bought some JST male plugs from them but they are bigger and take a lot more force to...

    Wildman Blackhawk 75

    I'm weak. I admit it. I caved on Saturday and bought the Blackhawk 75. I've wanted a 3" minimum diameter bird for a while. It lines up perfectly with the 75mm hardware I need for my Punisher 4. Out of the box it looks like this. But there's roughly 15" of empty airframe, so let's chop it...
