Effect of Flaps

[Old Koreelah]

I habitually warm up my Jabiru engine with a couple of fast runs along the strip (it’s usually pretty quiet).

At 2000rpm it will lift off and fly in ground effect. The plurry thing won’t land unless the idle is around 650.

I’ve heard that Jab engines wth EFI will idle happily at 350.

 A slight downhill and you'll float forever. Not good for GUSTS either. Needs spoilers.. I've encountered Jab owners who switch the engine off on short strips .Nev

Those spoilers that pop out vertically on sailplanes sure do the job and shouldn’t be too hard to retrofit on some designs.

They could be deployed while parked in windy conditions- better than tying a plank of timber along the wing!
