If you run the servos on seperate channels, you will have two connections to make when you install or remove the wing. There is a danger that you will cross them. At best you will have to reinstall your wing.
This is a very real possibility. I label each wire with a piece of tape that's got a big R or L on it. If I've also got retracts, that gets labeled RET. If I can't get this right, I probably shouldn't be flying.
So far, I haven't had to reinstall my wing.
