P-40 ASSEMBLY MANUAL 

 

 

 

 
The TBM P-40 was designed to be the best flying P-40 possible. Several minor changes were made to greatly 
improve the low speed and high speed flight of the plane. We hope that you enjoy the wide speed range 
capabilities, scale looks, and quick assembly. 
 
The TBM P-40 has these advanced features: 

-

 

Cowl screws are completely hidden. 

-

 

Wing is 3 pieces for very easy assembly and transportation 

-

 

Wing panels held in place using a machine gun to completely hide the screw 

-

 

Canopy uses a hatch latch to conceal the air valve, pressure gauge, fuel dot and switches. 

-

 

Optional spinner is CF, painted in Olive Drab or Red. 

-

 

Optional muffler for DA-85 is available. 

-

 

Ailerons and Flaps are properly hinged at the factory. 

 
IMPORTANT ASPECTS TO KEEP IN MIND 

-

 

The plane is not tail heavy like most warbirds. We moved the wing back and lengthened the nose, so the 
batteries don’t have to be strapped to the engine along with 5 lbs of lead. Mount the batteries last, and 
put them where necessary for CG reasons. We put our batteries as shown in the photos as follow. 

-

 

The plane does not required lots of downthrust like most warbirds. The airfoil is much more 
symmetrical, so it does not generate lots of asymmetric lift. We have no downthrust in the engine.
