Chaos definitely ensued, but only after I nearly lost my sanity getting everything working. *Patreon:* https://www.patreon.com/NicholasRehm *Free 3D print files on my website:* https://www.drehmflight.com/ *Flite Test’s video on this project:* https://www.youtube.com/watch?v=fGqlhI_vanM *Michael’s FPV Motion Simulator:* https://www.youtube.com/watch?v=RUl8RUT7FV0 *Peter's Flite Fest Video:* https://www.youtube.com/watch?v=6v_o_zH6UJQ Thanks to EMAX USA for sponsoring the power system for this project! Motors I used: https://emax-usa.com/products/pro-series-2814-730kv-brushless-motor ESCs I used: https://emax-usa.com/collections/electronics/products/emax-formula-series-45a-esc-support-blheli-32-2-5s Tip-jet helicopters are an old design that never really gained popularity due to their noise levels and issues arising from fuel plumbing through the rotor head. Electric propulsion fixes both of these problems, making an overbuilt electric tip-prop helicopter the perfect candidate for a giant RC combat helicopter. Despite the absurdity of this project, there was still quite a bit of engineering involved, from the structural components to the control system design. It even involved some engineering logistics to get a 15ft helicopter halfway across the country and set up in time for Flite Fest 2024.
