Does anyone have the spec for the 10K tower turbine mounting connection?

It as been a long time! 

Does anyone have the specs for the Redriven mounting system.  Several people are looking for a  drawings that show the number, size and bolt circle for the tower-to-turbine connection of the Redriven-10K.

Can anyone share that info?

If you are a former Redriven owner or employee, I promise not to tell where I got the info if you send it to me.

Warning about flange and structural cracking on the original installed


These pictures were provided by the maintenance staff at Presentation Sisters in Aberdeen, SD.
Safety Maintenance Alert Turbine Model: RPI 20kW with original "Flat Root" blades and original blade flange. These pictures are of a weld failure on the original installed flange and structural cracking on the original installed blades. The system has been running since April 2013 with a QED control system. It was lowered for routine annual maintenance.
QED recommends an immediate system stop and inspection of any systems in operation that are using original RPI blade Components. It is our opinion that these original installed blades and flange represent a safety concern.
*please note that systems running Round Root bladesets should also be inspected.
Please contact Scott Fouts of QED Wind Power with any questions.

Redriven owners - Scott sent a bunch of pictures but this one was the one that said it all to me.  If you have a redriven that is still running, be sure to inspect the blades for cracks.
