I have a T-rex 450 se v2 which I am building at the moment,but I am stuck because I dont know what to do with the excess gyro wire.I have mounted the gyro under the the tail boom block on the back of the heli.I have around a foot of excess wire with about two inches of wire that i will actually need.I dont know if running the gyro wire over its self multiple times will cause unwanted frequency problems or not.By the way im using a DX6 radio system.

Won't cause you any problems if you bundle the excess. Mine is folded over in a bundle about 1" long and shrink wrapped. You could also shorten the wire if you have the tools, but you will be limiting that gyro to similiar sized helis. I'm leaving mine long so that if the gyro in my raptor goes out I can swap it out if I need to fly the raptor. You need the extra lenght for the bigger helis.
Oh BTW, make sure the bundled wire is tied down so it can't get caught in anything.

i think i did something similar to darkbrid. i spiraled it really tightly into the frame, then folded it over in over in about a 1" long zigzag. zip tied it together and it fits snugly next to my reciever. the tail servo and gyro wire are just spiraled very tightly in a thin sharpie marker diameter

Alright thank you all for the help I just wanted to make sure before I mounted it and messed somehting up.
