1. Planned the locations of holes for throttle, prop and mixture cables as they pass through the gear tower. Trimmed the edge of the forward attach angle that holds the quadrant, where the throttle cable will pass close by. 2. The aftermarket DJI Deluxe Throttle Quadrant I have does not exactly fit the stock Vans enclosure, There are some slight corrections that can be made to make it fit better and look better. One of these relates to the gap between the top of the DJI quadrant and the top plate. I thought I might be able to use a couple of pieces cut from some 0.125" aluminum I had, but after I measured the gap at 0.080", I decided to stack two pieces of 0.040" together. I will flush rivet them to the top of the DJI quadrant, and that will hopefully stabilize the top plate a bit. I cut and prepped four 1-3/4" x 1/4" shims, then drilled six rivet holes through the quadrant. Next, I will clamp the shims to the quadrant and back-drill them.
