With the airfoil on the Eagle and the fuselage construction methods and materials I think you're asking for a very short model lifespan. IMHO that model just is NOT made to go fast and trying to do so will overstress the wing and perhaps cause it to twist and rip off or the nose will vibrate to peices. And that's assuming it doesn't just fold up at the bottom of a high speed pullout. And even if it does manage to somehow stay in one piece it's not going to go that fast thanks to the drag of that airfoil operating in the very low lift condition. And then there's the model trim that will be fighting you all the time.

You want to go fast? Make a quickie 500 type model for that 40. It won't be racing pace but it'll be much more fun to fly.
