Longranger Slats


Recommended Posts

The LR or straight L came without the slats. You will notice when flying that in a steep climb when the airspeed reaches about 60 mph the aircraft will begin to pitch up.... quite a surprise when you don't expect it. It has been a while so if someone can describe the speeds and effect better please correct me.


The L-1 and subsequent models had the slats added to eliminate this characteristic.

Quote from the Bell 407 FM:


"The leading edge slats are designed to improve pitch stability during climbs. "


They allow the air to flow smoothly around the bottom of the horizontal stab to avoid stalling it.


If you are concerned about whether the LR should have them, contact product support in Mirabel.

Good luck.
