    Help sizing BP charges for a BT-60 tube

    Hey Everyone, I'm working on an Estes Star Orbiter that I've heavily modified to include DD. This is my first experience with DD and I'm having some issues with getting the charges to pop the drogue out. I did some pop tests today with mixed results. I'm using the Christmas lights ejection...

    I want to adapt the ejection charge, whose material I don't know, to FFFFG black powder

    Greetings to everyone. This year, I will be participating in the High Power Rocketry competition called TEKNOFEST Rocket Competition, which is held in my country. In this competition, a ejection charge is used in which the material and weight data are not given. The only thing I know about this...

    High Altitude BP Charges

    I'm planning to fly around 50,000 ft this Summer. I know at this altitude regular BP containment methods don't work. I know aluminum style charge cannons will work (Nic L and Jim Jarvis), but they would be difficult to integrate into my avbay and recovery bay design. Thus, I have been looking...

    Low power dual deploy

    I know it's been done before. I also know it's not ideal due to lack of body tube thickness. That said, is there a descent kit or at least one that is more recommendable than the others for low power dual deploy? Looking to use C or D. Not using JLCR. I only wanna use black powder. I...

    Ebay with Metal Bulk Plates - Wildman

    I received an electronics bay from Wildman Rocketry. It is a very basic kit, 1 32mm fiberglass coupler and two bulk plates (See Pictures). I have never worked with metal bulk plates before. I was wondering if I could get some ideas on how to pass the electrical signal from my altimeter inside...

    Old Quest BP motors

    I recently purchased a dozen or so different Quest BP motors (b6-2 b6-4 a6-4 c6-3 and a D5-0p) from a vendor who had some leftover stock. I figured I would test some to see how they held up after siting in a box for a few years. Today I flew three a6-4's in an Estes Alpha VI, the 60th...

    Ideal pyrodex charge?

    Hi all, I'm trying to set up some pyrodex ejection charges in 2ml centrifuge vials and want to know how well I should try to contain the powder. With the vial completely full (~1.8g), and sealed with quite a bit of masking tape it went off with a sound a lot like a gunshot in a preliminary...
