General Notes

 
Mr. Mulligan is both an accurate scale model and a high performance flying model. Its lightness contributes to its durability, since 
a light model flies slower and if it hits something it does so with less force. 
 
The real Mr. Mulligan was a very successful and unusual racing airplane. It was built in 1934 by Ben Howard. In 1935 it won both 
the Bendix Trophy race and the Thompson Trophy race. What made the aircraft so different was that it could carry four people 
and luggage yet beat the special purpose single place racing planes of the time. It was also faster than the best Army Air Corps 
fighters of its day. In 1936 it lost a propeller blade during the Bendix race and crashed in the mountains of New Mexico. The 
remains were recovered by an airline pilot in 1972. Construction of the model is generally conventional but there are a few 
unusual features to make it easier to build and stronger. Please read these instructions carefully so that you do not overlook the 
unique features and make time consuming errors. Figure A shows the uncovered structure. Begin by building the fuselage, wing 
or tail first as preferred.
 

Fuselage

 

The sides of the fuselage are built separately, directly over the plan. Pin the 1/16" sheet side pieces to the plan, making 
sure you have the proper one on the correct side as they differ slightly around the windows. Add the 1/16" square side 
outlines and the rest of the 1/16" square pieces and stringers. Note that the uprights are not added until the sides are 
completed and removed from the plans. They go on the side that was next to the plans - on the inside of the fuselage. 
This makes the covering smoother.
