Can you provide more details of your setup?

Weight, severos, CG.

I'm putting a pizazz together and I was planning on putting a Tower .46 on it. From what I've read that won't be enough.

The only other engine I have is a OS .91 Surpass 4-stroke. The engine weighs 26oz with prop and spinner. Wire radio and servos (weighing 13oz) that would bring the plane to 6lbs 3oz.

I'm wonder with all that weight up front, if I can mount the rudder and elevator servos in the tail. How did you do it?
