I'm still putting my Pizazz together. I only have a OS .91 4stroke to put on it. It will be way over powered and heavy, but should fly.
From what I hear the Saito 72 is perfect because of it's power and it only weight 16.9 pounds.
If you have something at in the power range, you should be fine.

I should have mine air-born by Friday. I can't wait.
