I agree with Bill.


Here are a few more details I would=0Aco= nsider.

=0A=0A

 

=0A=0A

Choose a smooth hard flat wide runway with no cross wind to= =0Athe extent possible.

=0A=0A

 =0A=0A

Do not kill the engine in the air. These pla= nes slow down=0Arapidly without power.

=0A=0A

 

=0A=0A

Fly it on the mains, raise th= e flaps to make sure it stays=0Aon the ground and to maximize elevator effe= ctiveness, then shut down the=0Aengine.

=0A=0A

 

=0A=0A

Maintain a level attitude as= long as possible. After the nose=0Adrops apply heavy braking to minimize s= topping distance. Braking will transfer=0Amore weight onto the nose but ene= rgy dissipated in the brakes is energy not=0Adissipated grinding into the n= ose.

=0A=0A

 

=0A=0A

Avoid soft fields. Metal props can dig in and pole vault the=0A= plane at high speed.

=0A=0A

 

= =0A=0A

Wood props will break off.

=0A=0A

 

=0A=0A

Cowls are = strong with respect to the air but fragile in a=0Ahigh energy dynamic encou= nter with the earth. A small undulation in the earth=0Acan catch on the fue= l servo / carburetor and tumble the plane.

=0A=0A

=  

=0A=0A

Undulations in the earth = can also cause high G impacts resulting in airframe=0Aand spinal damage. St= ick with a smooth hard flat surface.

Without a nose gear, if I had a hard surface runway, I would choos= e to land on the mains with the engine shut down, holding the nose off as l= ong as possible.  I did this once in an earlier life with a nose gear = that jammed during the retract cycle.  But then I didn't have a prop t= o worry about. Thoughts, Comments??
