I've tried everything and I always end up with the same problem.

PMX 3
Master 2
Slave 7
%100 and %100

Problem:

When I move the elevator stick up, both elevators go down. The travel is the same for both elevators.

When I move the elevator stick down, both elevators go up but the travel of the one on channel 7 is about 90% of the master elevator (channel 2).

What is that problem?

I've tried channel 2 and 5, same problem.

Thanks.
