Internal vs external
 

I'm no where close to having to make the decision yet, but does anybody else feel that the internal would cause unnecessary stress if they got banged around? It looks to me that the external ones are better. .they have more leverage to stop the rudder in the event of wind or accidental tail slide, while the internal will put stress on the hinge and rudder spar. Thoughts?

Hi Tom,

This has been bounced around for quite some time over the year and in summary, the factory appears to not be particularly supportive of internal stops to say the least.

That said, the factory external stop designs are incorrect for the RV-7, so don't go shaving them down to the required length until you have your control surfaces installed and measure the actual clearances between the rudder and elevators.
