It is easier and cheaper to get a F3A model to be at the limit (5050gr) or lower than increasing the weight limit.

If the weight limit would get to be increased, then all the manufacturers of F3A airframes/engines will develop new stuff, and this will come with a price, then competitive pilots will see a dissadvantage, so the race to have the best will start all over again, meaning everybody will end up where we are today, and the complaint will be why not to increase the weight limit to 6Kg as the 5.5Kg airplanes are to expensive and the cheaper options can not deliver the same performance, and so on.

The F3A is and has been 5Kg for a reason, but that does not mean that the lower clases should not have a higher weight limit, this, in order to get more people into pattern, which has less interest nowadays, those are the clases that need to be changed, F3A has a worldwide standard, the lower classes are different on each country, and there is enogh room for change there, something that could also help to change F3A in the future if a trend is established.

My opinion of course.
