I cut a hole through the side and slid it through the opening that I cut. Worked pretty slick but spent some time playing around with shims to get it lined up perfectly. Incidence is set per the plans at 0 degree's. Nice thing about the Bridi kits is that he gives you the perfect longitudinal reference by having the fuselage top flat. I just measure from the plans and found the center point for the horizontal stab leading and trailing edges to be 1". So I cut a template to the profile of the stab root and transfered those same measurements and traced the outline on to the fuselage sides and then started cutting carefully.

Thanks for the comments on my XLT. I mainly built it to get some pattern time and get proficient with the maneuvers. I'm getting started with turbines and was looking for an airplane that I could fly the speed of heat with yet be very precise. The XLT filled the bill for me. Will let you know how she flies when the weather improves a bit and I finish getting the radio gear in. I used Robart pneumatic retracts and stuck my airtank just behind the trailing edge if the wing and glued it to the fuselage bottom skin. The FX-61 is heavier and longer then the older engines that were being used in these airframes so there is a known issue with it being a little nose heavy so I wasn't too worried. I also went with installing ailerons out in the wing panels (use one servo for each aileron) and mounted those just behind the retract mount plates. I actually used the plate to hold the front servo screws and then cut and inlaid 3" long piece of 1/4"square basswood stock for the rear servo screws.
