You can blow the plans up till it matches a .049 or till the square stock matches 1/8th and 1/4th.
The design shape looks good but has one flaw if for max speed the swept forward ailerons cause excessive drag when deflecting.
If you want to fly fast without penalty perhaps the following mod. The larger surfaces require less deflection during flat out speed runs yet when slowed down or in acro play they will provide you that extra thrill most desire. Of course now the leading line is straight reducing drag.
