Servo Extension Arms for 3D Foamies

Great advice from Leadfeather:

• For good 3D you should have at least +- 45 degrees. 
• Cut slits only if you have stiff hinges. If they are already flexible the slits won't help.
• The longer arms are pretty typical, especially for the 5 gram servos.
• Possibly increase the servo travel if your Tx allows. Most computer radios allow you to do this in the "travel adjustment" and also in the "dual rate/expo" set up.
• For me, more throw means I use more expo for nice control response.
