This is for jc4me2:

Use a 6 volt battery, max out the travel on you servos via your radio and you can even shorten your servo arm. Do all that on standard servos and you get a ton of torque. Just the 6 volt it a big help. I went to 6 volt exclusively. Based on much recommendation I'm using a pull-pull rudder in the Pizazz I'm finishing. I also used a carbon fiber arrow shaft for the elevator push rod with 4-40 wire.

I'm gonna weigh my plane in the next couple days. With all the load-lightening I've done I'm curious as to what the grand total will be. It feels light.
