The purpose of this thread is to document the building of a LOC Precision AMRAAM AIM 120C kit for my Level Two High Power Certification. There does not seem to be a build thread of this rocket already on the forum; I hope to fill that knowledge gap. All input/tips/tricks regarding this build are appreciated. I have a large format 3D printer and a 3018 CNC machine that I plan to use for some of the custom AV-bay pieces, but I will try to make it so that anyone without these can still build this rocket. I also plan to document the prices of everything used in this rocket in an excel spreadsheet to give anyone else an accurate estimate of the costs associated with a level 2 certification.
Building Techniques:
* 90-Minute epoxy for all structural fillets and connections, because this a paper and plywood rocket, the bond will be stronger than the materials used (assuming proper care is taken to prepare the surfaces).
* The epoxy will be measured using a digital scale that is accurate to +- 0.01g allowing for an accurate mixing ratio.
* every part put on this rocket will be weighted and logged using the previously mentioned scale, this will allow for a precise calculation of the center of mass, and allow for me to determine how much the epoxy and paint that is applied affects the weight of the rocket.
NOTE: These photos are what the kit looks like out of the box, I have an extra coupler because I also bought the 4" Ebay (Not included in the photo).
