The ground effect technique

I like the use ground effect quite a bit, free performance is always good to have, short field, short gravel bar, obstacles at the end, high density take offs etc.

I see the you are not a member. That is ok, membership is not required. I like your videos, they are interesting.

But if your goal is to publish your website (which I suspect) you should know that many of our members never look at the guest forum. So you are limiting your distribution. Significantly.

Our software allows you to select which forums you follow and unless you select a forum you don’t see it. Many learned long ago to ignore guest forums as they tended to get junk, spammers and the like. You can join COPA, Cirrus ownership is not required. And then you can post in some other topic that is followed more widely.

Just FYI.

Thanks for the info Roger, not trying to sell anything here, just sharing my passion and I post my sponsors at the end , thanking them.

Will check on joining COPA.
