Since we introduced the first real 50cc arf back in 2003 our competitors have been trying to find a way to one up us. One thing they have done is build planes with slightly larger wing spans. This looks good in an ad, seeming to be bigger and somehow better. I get people asking all the time about this.
We actually dropped the Yak 80" simply because there was resistance to 80" wingspan from people who had never flown one. You would not believe the idiotic converstaions I have had on the phone. Firs tone guy calls to say how much he loves his Yak with a DA-50, immediately followed by somebody who is telling me that the plane is too small, wing loading will be too great, it can't possibly be any good.
So when I brough out the Sukhoi at 85" span, I got plenty of calls telling me that the competitors' planes are all 87" and that has to be better. Rather than fight it, I made the wings a little longer. You cannot tell the difference between 85" and 87", but one cannot fight with human nature.
So EF made a new Yak that was 88" and now H9's new one is 89". In the military this is called mission creep.
But I digress. The Extra is 84 for a reason. It's exactly the right size for a good 50cc engine. You don't need a bigger wing. Nobody who has flown one has ever made any comment about not enough wing area.
It's possible to have too much wing. The plane will tend to not handle well in the wind and will be harder to land since it wants to fly along at low speed close to the ground, rather than settling in before the runway runs out. If this was not true them all the 50cc planes would have huge giant wings. But they don't.
It's all marketing.
