It seems that this question of identification on our models comes up on these forums on a regular basis. If people would read what is in the rulebook, most of the questions would not ever need to be asked.
In my post above, I only made reference to the CLPA section of the rulebook that gave the identification requirement for only the CLPA events.
In the General rules section of the AMA rulebook, the identification requirement reads:
"4. Identification: All models, except Indoor, will be identified with the owner's name and address or AMA number, on or in the model. Individual events listed within this (Competition Regulations) may have additional identification requirements which must be adhered to."
The AMA safety code does state the owner is to "ensure the aircraft is identified with the name and address or AMA number of the owner on the inside or affixed to the outside of the model aircraft." (Indoor models are excluded.) The AMA safety code does does not specify if that code applies to only models flown in official contest events. I am not aware of any AMA document that states this information is required for insurance purposes. I would recommend that if anyone has a problem that the Model Aviation magazine (an official publication of the AMA) publishes photographs of models built by AMA members that do not show any identification infomation, they should seriously consider approaching the AMA with that problem.
I have not researched the entire rulebook for event specific requirements regarding this matter. The CLPA requirement is quoted in my previous post above. Once upon a time, there were "Unified Scale Judging Regulations" that applied to all the scale events, including CL, FF and RC. In those unified rules was the requirement for identification which read "Contestant's name and AMA license number should be permanently displayed on the model in an inconspicuous location. No point credit shall be lost because of such identification." Note this rule said that the information "should" be displayed and that no size requirements were provided. During that era, some very imaginative locations and displays were chosen by scale modelers if and when they provided that information on their models. Also, I know of one scale airplane from that period that won the Precision CL Scale event at one Nats that did not have that information anywhere on it. Since that time and under the forward thinking of the Scale Contest Board, those unified scale rules were eliminated from the AMA rulebook and only a poorly coordinated set of CL Scale rules remain. As a result, there is no longer any CL Scale specific rule regarding model identification, which means that the AMA General rule applies. Therefore, CL Scale models flown in competition "will" have to comply with that AMA General rule. (No size or location requirements are specified there.) Maybe those who have competed at a recent Nats can advise if the identification requirements are being applied by the Event Directors.
Mr Reach: Thank you for toning down your pithy statement regarding the need to have the pilot's AMA number "plastered over the right wing". I hope you also understand by now that the number is not even required to be on the wing. I do not know anything about the MAAC requirements on this matter and will not comment. I am curious about your wording in a previous post where you used the word "curiouse". Maybe I should look in your non-contest pilot Canadian dictionary and maybe find that word in there around where the word "responces" is. (A friendly hint, the Spell Check function on this forum works really well.)
