With spoilerons it will waterfall like mad but falls to the side, probably because the motor is sideways and I didn't lateral balance the plane.
probably not lateral balance, you might need more right thrust. I had to add quite a bit to mine, it was very ugly to fly without it. (with no wind, go straight up with enough throttle that it will stop and fall back. does it do an automatic hammerhead at the top or fall straight back before turning?)
