On a profile with tail mounted servos, I go on the outside and mount them with nylon gear straps to keep them close. I've seen painted leads and covered over leads. If you Monokote, I'd suggest a Trim Sheet cut to fit and cover the leads. If you have to remove it for any reason, you wont need an iron to recover the lead. Just cut and stick another piece. For Ultractoe folks, the Ultratrim is self adhesive, and it can shrink too. You can use either right at the field if you needed to.
