Are you following the French P/V Yahoo group? Unfortunately the one person who was building one gave up because it was too heavy. He didn't fully explain so I don't know if it was too heavy for the engine/power or too heavy for European regs. Shame, I was looking forward to his progress reports. If my test flight isn't a disaster I'll update the old P/V thread. Let me know what you're up to if you decide to build.
Cheers,
Leland
