The Petrel excels in light wind conditions, being able to turn tightly in the slightest patch of lift and is equally happy when the wind blows. The combination of up-going ailerons and spoilers is very effective, so landing in tight spaces is quite possible. Once you get to know your Petrel we’re sure you’ll find that it’ll be your go-to model when it’s time to go soaring.
