Lets see, when is an ARF not an ARF? You could get super analytical and start down the road of assigning percentages of prefabrication values to each part (or system) of the plane in question like: is it an ARC or ARF, how much of the original did you have to replace or upgrade? Did someone just hand you the plane already assembled and preflighted/trimmed?
Here's my take on when an ARF is really an ARF. Drum roll please!
As the level of prefabrication increases, the level of ARFedness also increases by a factor of undetermined/ambiguous numbers so as to result in a condition of building atrophy with attendant flacidness of the artistic/creative cogent.
Treatment indications are as follows: begin treatment by clearing out that work shop/area. Follow this with acquisition of inspirational airplane plans that stimulate the creative juice centers of the brain. Make a large order of balsawood from your building buddies favorite supplier. Etc. Etc.....
Seek the supportive company of the builders/designers in your locale for the remainder of your recovery.
Should the presence of those unneeded ARFs that you have hanging around the shop space/livingroom now bother you or cause flashbacks, just remove them immediately and give them to some deserving beginner.
This transitional process should run about one complete season of building and flying of your new "hand built by you" creation to achieve effective transition to your new status as builder/flier.
For additional resources please refer to your nearest "metal" health professional.
I hope my attempt at some humor did not offend.
My philosophy of ARFs? The satisfaction of building as much of the plane as is reasonable and cost effective. (and that time, talent, resources, and space allow) Theres something about picking up the handle, connected to the lines, on the plane that I built (all) that just gives a satisfaction that goes beyond mere words.
Whats an ARF to you? It should be a self determined factor at the personal level at least to start with. IMHO
I should think that with all the examination about the argument attending to the BOM rule would have sufficiently brought enough thought to bear on this subject.
I wish you peace in your effort to reach enlightenment on your quest to know the essence of the ARF. May the farce be with you!
