It can be used on Aquila & Avantgard aircraft, and the bore hole is 10mm.

Since it is a two pieces type, it is a product that secures the problem of disassembling the mast lock due to the bending of the mast when estimating.

It is made thinner than the existing One Piece Mast Lock product, and when used in Aquila, interference with the Mast Lock can be reduced when the cyclic pitch is maximum.
