I bought 2 T100 a while ago. I finally mounted them. Before, I changed a propeller to one of them (I don't remember which one).
So I just mounted them, and tried them (very quickly since without water it is bad for them). But they really don't have the same sound. Are they both ok? Did I made some kind of mistake when I changed the propeller?
If there is a problem, is the first one or the second one the issue?
I feel the propeller of the first can move a little more than the other when they are stopped.
Let me know what you think. Thanks!!
