As long as the wings and tail feathers are straight, that is, no twisting warps, the difference you mention shouldn't be enough to affect the flying.

Any effects as a result of the error will probably be trimmed out when you first fly it.

Incidentally, on your first flight be sure to set the aileron travel as low as 40% rate or lower, or you run the risk of screwing it into the ground faster than you can blink!

Good luck and have fun. It's a great plane!
