Hi Janusz,

My comment on your picture was meant as a joke ! Ok, for the advantages of the beanie, there is a BIG difference in airflow between a FLAT surface (original cabin top) and the rounded Beanie (top of wing shape). First, the top cabin is right in front of the stab + elevator and anything that will help the airflow is a big PLUS !

On my 701 without the Beanie, the elevator would lose effectiveness real fast when speed decreased on landing. The result would be a sudden nose drop to the ground.

To fix this, I installed the Beanie and the elevator VGs. Now, I can hold the nose wheel up almost to a stop and the nose wheel lifts up real quickly on takeoff; almost immediately after applying power.

Added benefit to the Beanie : you gain some headroom too (i am 1m87) ! 

For the wing fences, they supposedly help when banking hard at low speed keeping the airflow flowing from front to back on the main wing. This I haven't experienced much so far. Bush planes and fire planes use them extensively I don't know if the 701 would ever need them but I wanted to try them to see and I had those slats brackets hanging there doing nothing...

If you have other questions, don't hesitate.

Hi Janusz, 

hopefully you don't look anything like your picture !!!

Happy flying with your 701. You'll see it is a nice tough machine.
