Attached is a pretty accurate drawing of my firewall (shape might not be

the required locations.  I don't have a good side view of the 13B or I would
draw it in with the proper cowl slopes and see how much room I have.  I
believe, based on info from other builders, that the CG on the 13B falls
right about the crack between the center housing and the forward rotor
housing with the Ross redrive doesn't it?  I think Mantyla's redrive is
about 14" long.  Will probably build his design.  I called him and he
sounded like he had really done his homework and offers a nice set of plans.
Don't have the money to spend on Ross' or Crook's redrives right now.

Thanks Paul, I look forward to seeing your design.

I need a couple of more dimension here Joa. What is the distance down
from the upper firewall hard points to the thrust line?

What is the distance from the firewall to the prop flange?
