Mark,
Looks are deceiving but the stock servos will fit. The instructions show a prototype strut. Just put the struts next to the lugs that are screwed into the wings, mark them and then drill them. We did it at field at Joe Nall, it took 5 minutes, I forgot my struts at home and had to rob a set out of my new kit. I also tap the lugs to 6-32 so that I don't need to install nuts on the screws, makes putting it together a little easier and quicker. Also it is not nec to cut the covering to lower the anti-rotation pin. Just file the slot down, take a piece of 1/4 plywood or bass wood, drill a 5/32 hole in it, then sand it to fit the open area above the pin. The pin is 5/32 and that is why you drill the wood to fit the contour of the pin. You then apply ca to the wood and install it above the pin. I did this on the 3 double visions I have put together so far. It is takes about 10-15 minutes and is a permanent solution that doesn't require cutting the covering. Concering the hatch latch, It is a tight fit going in to the hatch. just pull it forward into the hatch and it will stay put. after quite a few flights it will loosen and seat itself. I ended up using thin ca to harden the wood where the pin goes into the hatch.
