Thanks for the continued updates on the Sukhoi. Mine should be here this week. Please keep us posted on yours and your final setups as you continue to fly it.
The missing wing retention bolts you mentioned, are you satisfied with this method? The online manual shows these to be 4x25 wood? screws. What size hole did you drill in the tube for them? How did you add the weight to the elevator tips? What is the oz/in rating of the servos you are using for aileron and elevator?
