I considered moving the z bends to the inner hole, but instead I wound up drilling out all of the linkages with a #38 drill bit (the stock holes were slightly larger than a size #40) and now everything moves nicely with very little resistance and no slack in the joints. The only joint I couldn't get to was the one on the elevator control horn, because the elevator can't be removed from the tail section. One thing I did find when disassembling all the linkages was that the guides that I had installed in the fuselage for the carbon fiber pushrods had "leaned" toward each other while the CA was drying and were binding on the pushrods causing additional friction and drag on the servos. Had I not gone through this process I would never have noticed it and this condition would probably have resulted in servo failure and a crash. All this being said, I plan to build a Flatana with the knowledge, experience and endless frustration I have accumulated while building my Reflection.
Thank you all for your suggestions and comments. One thing I will add is that while a number of you have said that CA accelerator or "kicker" will help to speed up the assembly of these models, my manual for the Reflection specificaly said not to use it when joining the carbon fiber tubes to the leading and trailing edges of the control surfaces. I assumed that this had something to do with accelerator weakening the bond. When I build my Flatana I plan on using all the "kicker" I can afford.
