Loading the aircraft seems to take longer than its sister aircraft's and the throttle has no response physically from engines when throttle moved forward, throttle moves forward but no power from engines. Flaps are set, and Take off Config warning goes off instead of engine throttle
I have figured out a throttle issue solution that worked for me. I found the plugin on the 700 seems to lead as a the culprit as did the 800. I applied the B737x3_33H, only replaced 700 "plugin" with the 800 "plugin". after all the same systems across the Ultimate 737's. Those of you with the above errors it may apply but the full list of fixes seems is not fully listed on the change log on Xplane.org.
