	The D.63 was wood framed and covered with a mixture of plywood and fabric. It was a low wing cantilever monoplane with 5.83° of dihedral. Its tapered wings were based on two spruce spars and ply covered around the leading edge with fabric elsewhere; the Frise ailerons were constructed in the same way. The D.63 had no flaps but light alloy air brakes were mounted under the wings at 37% chord. The fixed fin and ground adjustable tailplane were ply covered, mounting fabric covered control surfaces. There was a trim tab in the port elevator.
