My UCANDO is here!!
So now i have a few more questions.
Should I:
1. Get a 90 oz Servo no matter what i have to do.
2. Put 2 3003s on the elevator and use 1 of the 3004s for the rudder.
3. Put a 3003 on the rudder (I am really just going to be sport flying it for now).
4. Any combination, but get a 6.0 V battery to get more torque.

sctcrash,
All three UCD's in the picture below use Futaba S3004 servos, that's 18 servos. I was not inclined to over spend for that many servos. Futaba doesn't overrate their servos and the S3004's work very well on these slow planes. They can do knife edge loops, blenders, etc. Keep in mind that the rudder has aerodynamic counter balance and the elevators have an even greater percentage of counter balance which takes some of the load off the servos.

I am trying to get the front throttle conrtol rod in and I dont get it. There is no place for the control rod to go to get around the fuel tank. the fuel tank fits fine, but once i put the control rod in, the fuel tank doesnt fit right anymore cause the control rod is in the way. .....
The second pic below shows where my UCD 46 throttle cable exits the firewall and connects to the Saito .72 throttle arm. The tank is stock. Flex cables are just another option and the one I prefer. They will tolerate a slight bow or misalignment and retain free movement.

I did cycle it the best I could. I turned it on and left it on until it was competly dead, then I charged it back up the normal way with the wall charger. I have done this several times and it usually lasts for 4 or 5 hours at the feild. Again, I may have switched it on when I put it in the flight box or it just may be time for a new one. .....
Take care not to discharge your batteries too many times until they are flat dead. The weakest cell in the pack will reach zero volts first and will be charged in the reverse direction as the stronger cells continue to discharge. There will come a time when the weaker cell cannot be recharged fully in the correction direction.
