    Yes, GDJ, it is specially designed for fins material based on рhenolic, good strength , low density, manufacturability.

    Seems to work well. I may try this once I get tired of Basswood. ;)

    Basswood good material, but requires skill for the best result. My way easier.

    Production method does not require skill and experience in working with wood, in the production is iron works.

    I see. Do you use hydraulic shears and other metal cutting tools for the phenolic?

    ... in the final form of the fins are not processed, only edge.

    Those look really nice! How do you ignite the upper stages?

    Good question, Qquake2k, thank you. Critical cross-section of the nozzle HELIUM-10 0.95 mm, internal igniter at a distance of 14 mm from the end of the motor. At the upper stage used motors without any additional technical improvements. That is, the motors can be interchanged. It's easier for me to show it in the pictures, than try to tell you about it. System of ignition works with any type of propellant charge, end burning or channel, complete unification.

    Photo with some of the events "indoors", popularization and propaganda in the "one bottle". Photo made before the Process started, then a few hours fuss, no time to shoot ...

    As they say in the good movies: "five years have passed...", unfortunately, the weather is not getting better, but rockets are launched regardless of this. Many different events happened. I will continue to tell for all about my rocketry experience. My English has not improved, I ask for understanding as much as possible.

    April 12, 2014, the anniversary of the flight of Gagarin, this time at VDNH was a big reconstruction, our launch pad moved into the courtyard of the House of Culture.

    The launch weight of the rocket is about 40 grams. Trust curve of motor following. 20140416_165855.jpg G12-3.jpg

    This is lovely stuff, thanks for sharing!

    Any chance you could take a pic of the motor that goes with that thrustcurve?

    And the flames on the later ones look more yellow, different motor I presume?

    Yes, different motors and different solid propellant formulation. Model rocket motors tend to be a strong compromise for manufacturability and low cost, as a consequence of this low case pressure. Different color of the flames is the effect of solid propellant components for sustainable combustion and a certain burning rate. 01m.jpg 02m.jpg 00094.jpg m07.jpg
