RE: need advise for qm40
The 2 oz under the wood is for strength. You will still need to glass the wood on top for finishing. I've never glassed under the sheeting before, so I'm not sure if you need a bagging system for that or not. I'd put a post in the composites or pylon forum to get this answer.
For a fuel tank, I would use a 6 oz tettra bladder tank. You do not want that expensive Nelson sucking air through a standard tank. You can get these tanks at either www.pspec.com or www.jettengineering.com
For the servos, you can go with Hitec 225s (Nylon) for elevator, rudder, and Aileron, and Hitec 85 or 225 for fuel shut off pinch.
If you uncomfortable with the hitecs, many people are using JR 3121s or Futaba 3002s.
