Mini Tailsitter VTOL

thingiverse

This is a work in progress. Non-scale drawing of design by Flite Test Forum member slembcke, making small VTOL tail sitter plane (fixed wing). https://forum.flitetest.com/index.php?threads/mini-tail-sitter-vtol-wing.36637/#post-369841 I made changes as it's not to scale anyway. KF2 step Airfoil design (Kline-Fogelman). Made with Dollar Tree Foam Board, also known as Adams Readi-board. Drawing is 400mm X 280mm tall when standing on its tail. Rudders are fixed and rudder is by differential motor control while in plane mode. In VTOL mode Yaw axis is by Elevons. He originally powered it with 1304 brushless motors in front of wings. He eventually moved to 1806 motors midline in wing. He used custom programmed Seriously DoDo controller from RMRC. I plan on following up his work. Not being a programmer I will be using KK2.1.5 Mini Flight Controller which is 36X36mm form factor. Stock firmware has been replaced with OpenAero2VTOL firmware. I am also planning on using 1806 2280 motors and 5" X 4.5" Bullnose Propellers. Airframe mostly assembled, no electronics as yet. Some adjustments made in scratch build. Pod widened to 60mm. This should allow a full size KK board. I will post more updates soon.
