You don't want the servos touching each other so I would try for 1/8 " gap between them. By the time you have the holes drilled and the servos mounted solid they may be closer together than you started. Other than that the way MinnFlyer has shown for mounting them will work well. The LT is a great plane to experiment with. Later on you may want to convert the wings to bolt on. You can email me for an easy way to do this if you want. I hated the rubber bands after a while and found the bolts more user friendly and not as messy.
