Hey little buddy, sorry I have not answered your questions, but you seem like you are coming along pretty well. As I am sure you have found out, you are not going to have any balance issues such as adding weight. I had the servos in the tail. I like to fly very tail heavy, so it was perfect for me. Your engine is amost 20 ounces lighter than my F50.

Are you using the aft servo tray. I am assuming that you did considering that you thought that you would be nose heavy. I had a redundant power system and put all three batteries right under the wing tube. If after you have done this, your CG does not mover forward enough for your flying styles then you may have to consider putting the rudder servos in the middle. FWI, my CG was about 2 inches behind recommended and flew inverted hands off, but ballooned on landings.

You did not mention what servos that you are going to use. I really recomend using something around 130ozs minimum. Hitec 5645s are very nice. The yak has to much surface area on the ailerons for a 90oz servo to give you the centering and response needed to fly this plane.

I will be checking back to see how your progress is coming. What is your weight. Do you have a redundant power system. It is also possible to put your batteries over the motor box under the cowl. If you are worried about EMI, just twist the wires coming from your battery pack to your reciever. This can be easily down by sticking the male end into a drill, and momentarialy pressing the trigger.
