This is the final iteration of the turboprop, with the installed Mejslik carbon-fibre propellor. For most runs, I have derated the turboprop to 140,000 RPM on the gas generator, which equates to about 8,000 RPM on the prop. The energy output I would estimate, at this level, to be 20% below its maximum power.

If you want to simply view the completed turbpprop, rather than construction, see these links:
