Everyone around here has at least one SE. We use a SIG Kadet landing gear and 3 1/4" tires. The gear mounting plate is a weak spot. Brace it well. I will put a carbon fibre belt on the outside of the fuse in that area for stiffness. I don't think you will see it under the covering. Make sure you add an extra strip under the top turtle deck stringer. The stock one bows badly when the covering is shrunk. Cut the hinge slots before you put the triangular shape on the elevator and rudder. We all add some sort of wingtips. Don't even think of using bolts to hold the wings on. That fuselage isn't braced for that in this area. Lots of stories on other SE threads here about wings pulling off when bolts are used. We use a tie wrap between the stock hooks. My hooks are just screwed and epoxied in, but if you can still get access to the inside of the root rib, I would install 2/56 blind nuts. Another problem area is the push/pull rods from the servos to the tail. I bought carbon fibre tubing. It is very stiff. I put that inside the outer guide tubes to keep them very straight when glueing them in. I then used that carbon tube for the pusrods. You must put a short length of aluminum tubing over each end of the carbon. One has to go on after the rod is installed. I CA them on and the unthreaded part of the threaded rod also. Just run the threads into the carbon tube about 2 threads. Because the servos are very near the bulkhead where the tubes come into the radio area, make sure you elongate the hole for the elevator guide tube and don't glue it to that bulkhead. This allows the tube to move sideways as the servo arm tracks in its arc. We never take the wings off. The SE fits in any normal car, (mine is a Volt), fully assembled. Here is a picture of my 2 year old SE. I am using an OS 55AX and an 11-6 APC prop. I also have floats for the SE with another gear pad just shead of F-4.
