I certainly appreciate all the comments and recommendations.
Handglider, thanks for the suggestions. I am going to stick with the Brio, though and see if I can follow through with some (if not most) of the suggestions for improvements made by several people in this thread. I hope I don't have to give you cause to say "I told you so"..  but I'm gonna go forward. You have helped me by some of the issues you have brought up and by some of the fixes you proposed.
The Dude: Yes, could you post pictures of what you did and how you did it? I am especially interested in the carbon rod improvements you made to the elevator. If you can, let me know what size carbon rod(s) you used for the 'fix'.
As for the elevator control rods, I have a supply of Sullivan Composite precision rods (carbon) and will probably go with those.
I fly an Excelleron 90 with an OS 1.20 AX aboard. Flys just great, however, I DID have to make some changes in the throws even those recommended by the manufacturer. They were to radical, in my opinion, so I changed them. The CG was right on with that engine and it flys exactly as I would expect it to for a 90 size pattern plane.
I am NOT into 3D so I won't be doing anything radical like that with the Brio and will definitely take heed regarding the rudder/elevator/aileron throws.
Background.. I have a Tiger 60. It was my second aircraft after I got rid of my training wheels, and my first ARF. The trainer was an RTF NexSTAR. Anyway, I asked my instructor to maiden the Tiger 60 for me. He noted that the elevator was quite 'squishy' and soft to the point where it was almost ineffective at higher speeds, such as coming out of a loop. In fact, it almost crashed because it would not recover from the loop very well. He managed to land it and we looked it over very carefully. Well, as it turned out, the elevator pushrod would flex with the guide tube within the fuselage because I did not have enough support points along the tube. I was using Sullivan Golden Rods. The Tiger 60 has a flat bottom so I removed the covering all along the bottom which gave me direct access to the guide tubes for both the rudder and elevator, and I epoxied them in place at each of the formers. I also added a length of 2-56 wire inside the last several inches of the Golden Rods to the point where the rods went inside the fuselage a couple inches. This fixed the problem AND taught me a valuable lesson with regard to handling and sloppy elevator control rod (or any control rod for that matter), so I will be very VERY cautious with the Brio rods to the rear of the aircraft. I will also look closely at the control rods on the ailerons.
Thanks again, guys. Hopefully I can make this thing fly like it is supposed to.
Oh, HandGlider, I may STILL buy a Quiet Storm, just in case..   
DS.
