What does everyone think a good starting point for the CG is??

I'm with Bob on the metal hinges. I've had planes before with them and, alignment, waiting on epoxy, Rf noise, waiting on epoxy, rust, waiting on epoxy, sloppy feeling and waiting on epoxy kind'a made me not like them[X(]. I've had great success with the Radio South "blue" CA hinges but, I don't know how they are compared to the available slot in this application.

Great info here, thank you to all!!

A very Merry Christmas to all....
