#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.
