This is a re-design of v1.0 - Not all my designs work out the first time. :) See the latest updates below.The first design was optimized to require as little machining as possible to be built with the equipment I had and using 3D printed parts for support structures. In v2.0 I threw some professional optimization at the problem to reduce shaft deflections, improve tolerances, structural stiffness & mitigate vibrations.Update - 2021.04.03The test results indicate the engine is way underpowered for my design requirement and will only deliver half the thrust before running out of torque. - See results located in the photos folder for details. Update - 2021.03.27Vibrations remain excessive yet manageable. THe system was able to test successfully up to 19000rpm without major issues over multiple runs. *Notes below are not reflected in the CAD model available currently.Update Log:- Results added to photos folder,- Photos uploaded of the final system,- Jeti Mflow sensor added to measure SFC, http://www.jetimodel.com/en/katalog/Duplex-2-4-EX/Measure-Sensors-EX/@produkt/MFlow-T-EX/- Snapper clutch system added, https://www.davesmotors.com/Turtle-Racing-Snapper-Clutch-Short-Long-RC-Engines-HPI-Baja-Losi-5ive-DBXL-Go-Ped-3001-3002?sc=12- Rubber pads mounting pads added between main support brackets and base plate
