Hey Tom. I know nothing about the RV12. Just wanted to say Hello! I live in south Alabama. I am originally from Paducah and make it back there several times a year in the RV7A. Nice to see a builder from Western Ky.
Tom, you might want to consider installing the belts in a manner that does not allow them to be mixed up over the flap handle and cause an interference. One male, one female in the center.
Tom, any Open lots? I am looking for a retirement home.
