#122MM/LA INSTALL Low Profile Low Drag INNER GEAR DOORS:
This mod removes the stock bubble doors which utilize the large drag producing
teardrop (Royalite) fairing located on the wing bottom, and requires the break pucks to be
rotated while replacing the older doors with 205 style flat inner gear doors.
With the brake pucks reversed the doors are much flatter when retracted which
presents a far more streamlined gear closure presentation. While the aerodynamic
streamlining of this mod also reduces the working load on the gear motor/transmission in
transit while. This mod is good for 2-4 MPH gain at cruise as well. Price includes
rotating brake pucks to create a lower profile and less drag.
