Dear all,

As most of you know, the amendment proposals that were not discussed during the last CIAM Plenary will be presented again at the next meeting.

One of these proposals may need further discussion. It concerns the deletion of the weight limit for F6A airplanes. It has been pointed to me that the amended rule (2 m maximum wingspan, no weight limit) woudl open the way to multiplane monsters (think about a 2-metres, 15 kg, DA-150-powered Ultimate. This would obvioulsy negate the spirit of the present AA rules.

One of the options I was offered was to further limit the wingspan for biplanes, as it is done with some freestyle classes. However, thinking about it and noting the fact that biplaned have completely disappeared from the competition circuit for years., I tend to think that the most adequate solution would be to limit AA competitions to monoplanes.

Your input, please.

My dear Guy,
As I told you in the past, I cannot see why we need limitations to F6A models. I advocate leaving the options to the pilot, with the 20kg limit for F3M. We have a regular F3M contest schedule in Belgium, with about 15 pilots flying four nationals and a well-attended international meeting. Most of these pilots declined participating to the F6A selection contests we ran last year because their models did not comply. Only one pilot did purpose build a model and eventually was selected for the WAG. There is no question about the attractivity of these large models flown on music in front of the public. And remember that the present rule allows 15 kg jet models to compete. For these, the span is a MINIMUM of 1.8m and no maximum... Why should propeller models be limited when large and heavy jets are allowed. Maybe we should first decide whether accepting propeller aircraft, jet-powered aircraft and helicopters in the same category was a wise decision...
Thanks for promoting this discussion.
Robert
