I was able to dedicate some time to working on the Extra SHP today after working on some honey-do-list items.
The Extra build is very straight forward and has offered no
looks on my face. The parts fit has been excellent with all pieces and surfaces have fallen right into place. Many of the building steps are very routine procedures as with any arf model. I did however confirm that all the CA hinges are PRE-GLUED to there control surfaces. What this essential means is the ailerons and ca hinges were ready to glue to the wings, the rudder and ca hinges to the vertical stab and elevator halves and ca hinges to the horizontal stab. This greatly speeds up this step of the building process.
As Scott method earlier in this thread the control surfaces on the Extra, expecially the rudder (HUGE) and elevator (EQUALLY AS HUGE) are some of the largest I have ever seen on a model this size. The horizontal stab on the Extra sits slightly lower then the full-scale Extra SHP. I believe Ben or Scott can touch base on the reasoning behind this. You might want to watch however using full down elevator while taxing as it looks like the elevator could drag some. The carbon fiber landing gear really sets the Extra SHP apart from any plane in its class. It gives the Extra a very scale look and appearance on the ground. The landing gear plate looks to be very strong and capable of withstanding less then perfect landings.
