RMFISH,
Like you I planned to do a DEPS setup on the Focus Sport I recently assembled for a friend. I discovered there is a laser cut plywood bulkhead inside the fuselage just ahead of the stabilizer leading edge. The DEPS is rather bulky in the same area and there is very little access to modify that bulkhead without damaging the covering or weakening the tail structure. While I am sure anything is possible given sufficient motivation it really is opening a can of worms. I discovered that without completely removing a significant amount of that bulkhead the rods would bind unacceptably. FWIW, Mike.
