Dan & Leon,

Sorry I overlooked the aspect of easy  access in my response to Dan's question.

I am not flying yet, so can't give a personal testimonial on how easy the 
pins are to remove and install.  I can tell you that there is a trophy 
winning L IVP (1st at Arlington, 3rd at Oshkosh) with our hinges and the 
owner is very happy.  Last I spoke with him he had several hundred hours on 
the plane and still was pleased.  Jim Rahm has hinge fasteners on his 
EngineAir V8 powered L IVP and he pulls them at every airshow between demo 
flights.  His are the aluminum hinges because we weren't making ours when 
he built his plane, but I think he's happy with the concept.

I do know that every time I remove the cowl from my Beech Sierra (and the 
other GA airplanes I've owned), the task of removing the fasteners and then 
lining them back up each one at a time has been a real drag.  I don't think 
I'll miss that one bit.  We recommend silver soldering a hex head bolt on 
the end of the pin wire and having a locknut embedded in the cowling.  You 
simply insert the pin, engage the threads and screw it in for installation 
- do the reverse for removal. Easy and quick.  The pins are undersized for 
this application, so that friction will be appropriate for adequate 
stiffness, but they slide to place with hand pressure.

Hope this helps.

Regards,
John Barrett
