The thing is is that the bevel on the aileron itself and the bevel on the main wing are maybe a millimeter from touching and going flush.

The bevel on either part has nothing to do with changing the deflection of the aileron.

So turning out the clevis is going to do me no good. Turning the clevis will take up that mm but so will the radio; but easier and faster.

Turning out the clevis certainly won't do you any good. It'll change the aileron trim, but won't do a thing to the aileron throw. To get more throw, you move the pushrod connection on the aileron horn closer to the hinge line.

And the radio can change the trim, but is the least sensible way to greatly increase the throws. The radio endpoint adjustment or deflection percentage is good to fine tune. But going over 100% winds up decreasing the accuracy of the control.

That is why I am baffled as to why it so slow. I guess I am just going to have to get it to the field and keep playing with it. Other than that it tracks beautifully... But I'll turn the clevis

It's not baffling. It's either not getting enough throw or enough force to hold that throw under load.

To make prop tips show up better, paint them white. The paint won't add appreciable thickness to the tips, and therefore won't screw up the aerodynamics out there. The paint also will have a chance of staying on the tips. Tape won't have a snowball's chance of staying for any length of time.
