The X'Air certainly does, which is a very similar wing - and both aeroplanes are derived from the AX3. Looking in the TADS the ailerons are just shown as ±24° but there's an asterisk next to that figure which doesn't seem to correspond to anything. I wonder if there's a correct "ailerons neutral" setting angle being missed here.

That said, it's the other way around - ailerons-up gives reduced elevator authority, which the (otherwise far too twitchy) X'Air needs. If the ailerons are too reflexed upwards, then it's possible that an aeroplane doesn't have enough elevator authority. So, drooping the ailerons a bit may well fix the problem on this aeroplane?
