As am I, Kang.

 Strength wise, one could easily build a 0.012" thick motor stick that could handle the tension. The issue is the twist - I don't think anyone could launch a model with wing twist approaching +1.5" left and minus 1.5" right.
 

 If there is a method, please share! I've never figured it out. Mine just dive right and into the ground they go. You can easily see the covering get forced down on the right wing due to the aerodynamic forces after launch. Burn off a few turns to a lower torque and the twist is reduced enough to make the model launch-able. I could add a lot of incidence to the wing to help, but this comes at a cost at other parts of the flight, I.e. Cruise.
 This is the reason why I think less torsional twist is desirable. The only way I can think of doing this easily is by going to thicker wood or larger diameter motor sticks.
 

 Someone has told me I'll take all the wing wash I can get, even going to lower diameter motor sticks to get more. I don't know how he can do this without diving in to the right when launching at extremely high torque.
 

 Regards.
