Fadi, as a guide, the AX .46 should do around 12,000-12,300 with the APC 11x6 at peak and should exceed 13,000 rpm with an MA 11x6.
Harry I suspect you may have reverse transcribed the figures you recorded. You aren't
seriously suggesting a square tipped MAS paint stirrer tachs 1000rpm
FASTER than an APC prop of the same diameter and pitch?
