Anyone know what kinda' temps a PTO crank end sees? I'd like to try 3D printing a belt driver for my UAS ride for a PRD Fireball... Hegar doesn't make a core for them, nor does anyone else -- they were too "rare" to justify it. But a 3D printed part would be cheap and easy to try. As long as the crank temp stays below 200° I think I'll be fine on tensile strength of material. With no clutch to build heat, I'm thinking that it's do-able? What are your thoughts.... 20mm crank stub with a rotax taper...
