I have a question about the slip.

With the lazairs up turned tips turned sideways against the airflow, I wondering if there are any issues with strength, turbulence or buffeting of the lower wing.

Did you feel anything like that at all?

I was also wondering about the forces on the tail in a slip, and I thought I had read somewhere that it was not recomended due to someone having a tail failure of some kind, due to a slip....do you have any thoughts about that?

Also in my sailplane training days, they advised you to stop the slip at least 50' high so you have time to straighten out and establish your new descent rate for landing.....traveling at twice the speed of a Lazair though so there was less time to react....so maybe we could take it down to 25' for the Lazair as a good rule for safety.

It was very impressive however and good to know the Lazair has another method of descent control, besides the engines idling.

Thanks for posting the movie.

A slip in a Lazair is very stable. It feels different than in a conventional aircraft as the turned up tips keep the airplane relatively flat. There was some concern over the strength of the tail in the early models, but when rudder pedals were introduced as standard items, the areas of concern were strengthened.

It's good practice in training to stop the slip at 50 ft. However, once you are comfortable with your aircraft, there's no reason why you can't go lower. When I fly the Tiger Moth, there's zero visibility over the nose, so I slip down to the last ten feet so I can get a better view of the runway.

I've had days in the Lazair where there is sufficient lift that I maintain altitude while gliding on final. She loves to fly, so the slip is a great way to get her out of the sky when you need to.
