with my mSR i have 4 batteies in rotation, and notice that when i switch them my rudder trim goes way out of wack so much so that one battery i need to trim all the way left. and the other all the way right, and then sometimes thats not even enough. and the other two batteries run properly! is there somthing im missing here?? or when i switch from battery to battery should i be shutting the Tx off? sorry for the noob questions im just trying to figure this out.
