Superb 777av8r!
As the starter of this particular thread, I have read the various posts with interest.The posts from 411a, although highly predictable, and similar to my great-grandfathers, (he flew in the 40s and 50s), and are always good for a laugh.Thank you kindly 777av8r, your post is excellent, ive copied it and handed over to my FTM, if you dont mind by way of explanation of said add-on procedure.Pete.
