RULES PROPOSALS—we have them!

Following this short introduction are summaries of the proposals for the 1999–2001 Competition Regulations. Yes, 2001—remember, we are on a three-year rules change cycle now. The current Competition Regulations will be in effect until the end of 1998.

In many cases the proposals as received are too lengthy to publish in their complete form; when this is the case we have summarized what we felt was the intent of the proposal. The complete text of any and all proposals is available by calling the Competitions Department at AMA HQ.

You will hopefully notice that we have tried to publish actual proposals in as many cases as possible, in response to member requests. This becomes a real (and expensive) space issue in the magazine, so please understand when the entire proposal is not printed.

OK, the proposers, the Contest Board chairpersons, and AMA HQ have done our part; now it's your turn. For this process to work, you must read the proposals in which you have an interest (the events at which you fly or officiate). Get out your copy of the 1996–97 (98) Competition Regulations and see what is being suggested as a change, then decide if you agree or disagree with the proposal, then contact your District Contest Board member and let him or her know your feelings. These people are in place to represent your views; however, they can't do that if you don't contact them.

Remember: You are the AMA—not just AMA HQ or the elected officials. AMA is the membership. You control what happens, but you must participate to have this control. If you don't, shame on you. I can't tell you how many times we get calls from upset members complaining about this rule or that, only to find out that they did not bother to comment at the proper time.

This is the proper time; get your comments to the Contest Board members for your district.

Till next time ...

1999–2001 Competition Regulations

Basic Rules Proposals

The following is a synopsis of the rule proposals that have been submitted prior to the deadline as changes for the 1999–2001 edition of the Competition Regulations. The initial vote on these proposals by the respective contest boards will occur during February 1997. Ballots from the contest boards must be postmarked by February 28, 1997. All AMA members are invited to comment on the proposals by contacting the contest board members from their districts. Their names and addresses can be found in the "Competition Directory" published monthly in Model Aviation.

Some proposals are not reproduced here in their complete form because of their length. Every effort has been made to assure that the intent of each proposal has not been changed. Copies of complete proposals are available by contacting the Competitions Department at AMA HQ.

All page references in the text to follow are from the 1996–1997(98) Competition Regulations.

General

No proposals for the General section have been submitted that require contest board action.
