i have a blade cx2 and mcx and i use the same controller. the lp5dsm one. it has a travel switch and i don't under stand what its purpose is? i noticed while hovering my mcx that when i am in a stable hover and turn that switch, it makes the heli loose power and drop a little bit. what is it? what can i use it for? also, when i want to fly my cx2, what are the dip switches? which ones are up and down because i forgot them. thanks!
