DPM Ultimate 40 strange snap roll issue
 

This is a new one on me so I thought I'd ask if anyone else had seen it. Yesterday while flying my DPM Ultimate 40, Saito 72 powered, I found it paused about 3/4 of the way through a left snap roll. This was using only elevator and rudder. With ailerons thrown in it does not pause, nor does it when doing snaps to the right. If I continue to hold the rudder and elevator it will start snapping again and does not pause again, just on the first snap. This was kinda weird to me and it has not done this before. The first time it did this I landed and checked to be sure everythign was tight and found nothing loose or abnormal. Yet it was very consistent at pausing at the 3/4 point in the snap at high and low speeds.

FWIW, I have standard JR537 servos on the tail and Hitec 225's in the wings.
