Yes, the Egg redrive has no failures yet, from what I know.

However, he seems to have taken the "build it strong as hell" approach and
doesn't use any kind of damping, such as elastomers, sprag clutch, etc. He
is also using a heavy flywheel that helps to smooth out the torque spikes.

The result is quite a heavy unit. Still his FWF package is competitive with
Lyc on a power-to-weight basis. Not bad at all.


Regards,

Gordon.

Your story is just another reminder that gearboxes are one of the big

is not really a box that I would consider completely trustworthy.


Really? Not even Eggenfellner's? I haven't heard of any failures of
his design yet, but I haven't been actively following Subaru
conversions.
