Great Greg!

So, with some effort, we could easily be under 60 oz's with our build. That should work out pretty good then. Well over 50% thrust to weight ratio is easy to acheve then and safe to fly. I am one to love "more-power", and rarely build with less that 180% thrust-to-weight ratio for 3D.

I see the photos apparently indicate full-size servos. Maybe HS-55 servos will work the tailfeathers, with a HS-425BB on the ailerons, maybe get us even lighter... What servos are you flying? On a trainer, not a lot of torque needed, small throws with good mechanical advantage.... hmmm. How do you feel about servo torque requirements?
