The current patterns are designed for a large plane -flown in a large footprint - make no mistake about it .
This is what drives the need for larger models
The time used for flying any sequence with a smaller model , compresses with the size of the footprint.
Plainly -a smaller model is at a disadvantage right from the start.
My comments on large models were made because the smaller ones are effectively, non competitive in upper classes
A really good flyer can fly the Unlimited with a 33% model.
But you must have enough power to open up the box to regain the TIME advantage the large models enjoy.
The model then looks very small -so again - a disadvantage.
To ignore this situation is to ignore the obvious.
The local events feed the regional events which feed the national events .
At the local level , the number of upper class flyers has been reduced -costs and size are a real factor.
To preserve the event (IMAC) there really needs to be some sort of classing which stops the "biggest" from dominating .
If not - then simply accept that the total number of participants will diminish.
The cure is really easy .
Just put size limits from Basic up to Unlimited
Not itty bitty size limits - a 15lb/ 20lb/ 30 lb then Open weight graduation.
Or some such class identification.
The new guy with the 40% model may feel shut out from Basic - but this is really a non issue if what is wanted is a method of keeping IMAC a viable event for the majority of fliers..
