None, at present.

However, there is a vast difference between permitting a modest weight allowance for the lower classes - which we already have - and institutionalizing an across-the-board, whopping weight increase of 500 grams (almost 18 oz) for all classes, which is an open invitation for more powerful propulsion systems, higher-capacity batteries and new airframe designs. These will, of course, cost more.

Yes, the FAI 5kg weight rule will keep this in check somewhat. But this assumes that FAI is the destination class to which all aspire, when in fact a large majority have only the talent, time, and resources to shoot for a high placing in Masters, which is to a much greater extent the destination class in this country. To think that a 5.5kg allowance would not invite "technology creep" up the ladder to Masters is unrealistic at best.

This all started off with a couple of guys with models a couple of ounces over 5kg. Now we're up near 18 ounces?! Where does it end?

The simple solution would be to extend the current 115g allowance to Masters and be done with it. This would resolve nearly all of the complaints we have seen lately and would not throw the door wide open to a technological race.

And quite frankly, if somebody has attained the skill to fly Masters and can't get his model under 5115g, he needs to seriously re-evaluate his whole equipment situation.

But not to worry. I know that this reasoning - which has been presented before by those with a deep knowledge of Pattern history and far better credentials than mine - isn't going to sway the opinions of those seeking an easy answer.
