Geez, my servo s on my Knife are pretty easy. I'm not sure I did it like the kit calls for, but this is what I do to most frofiles anyway. I have the hatches on the top of the wing, and the servos mounted on hardwood rails that are glued to the bottom sheeting,
My tank is in the LE of the right wing, and to get it out I would probably have to remove the throttle and rudder servos. I can take some pics if you want to see my set-up.....gator
