Barring that, it could be a throttle problem inside your Dx6i's throttle gimbal.. have any other planes to test it on?
Also triple check that throttle travel in the programming of the Dx6i can go to 100%, and check throttle trim as well.
1) Tested my dx6i just now on another su26xp and t34 mentor - works fine.
2) unplugged the motor, binded the su26xp with the transmiter, checked voltage on the (+) and (-) - no voltage. But there is voltage between the very left pin (the for for brushless ESC) and both (-) and (+).
