[edit] Aileron travel looks good as far as I can tell. In the up direction, it has way more travel than required. Like 40 degrees or so when it hits the stop. There's a little interference from the push tube rivets against the spar right at the stop. But the table on 15-2 of the manual sez that the max travel is 32 degrees, so this should get limited a bit more (by fabbing new stops?) I guess up travel gets limited somehow so the stop never gets used in practice. The stop is there to prevent the bellcrank from flipping over, but other things have to go wrong before the aileron can ever get to that point.
In the down direction, the travel is close to the limits required by 15-2. I did a crude measurement of 15 to 17 degrees, which are the min and max travel limits. It appears to be limited by the short push tube rubbing against the cutout in the rear spar. As the aileron is pushed down, the bell crank is rotating outboard, and the push tube is also trending outward. At the limits of the travel, it starts hitting the spar. But there's no point worrying about it until the whole system is put together. Then the real behaviour will be be determined.
