RE: HEY! LET'S BUILD A SPEED PLANE!!!
Interesting design Sean, but could I make a could of suggestions?
Wing - advancing tips are a lower drag design. What are advancing tips? As you move from the leading edge to the trailing edge, the span increases.
You can reduce the size of the ailerons. Inboard from the tips like you have them is good.
A straight leading edge with all the taper in the trailing edge gives a slight effect of a forward swept wing. Helps lower the spanwise flow of the air, helps to decrease the wingtip vortex.
Fuselage - looks pretty tight
Tail - since the prop size is pretty small, you don't need much vertical surface, especially with such a long fuselage. A higher aspect vertical would be more effective and lower the drag. Horizontal area only needs to be around 12% of wing area, though 15% is more stable. Again the long fuselage helps here.
General - anything that reduces surface area lowers drag.
