6B 6 Rotor Flames
A few flames from PPRE's new 6B 6Rotor
Handbuilt 4-Rotor Engine
This was a project that took about five years of weekends to put together. There was a lot of trial and error as jury-rigged parts were improvised and revised, leaks were identified and plugged, and byzantine electrical diagrams were decoded. It still does not run smoothly, as there likely is a problem with the intake system that has prevented smooth timing at idle. But she runs! lots of people wanted to know where the E-shaft came from: it was custom ordered from a shop in New Zealand.
