Thanks Dave, im about ready to balance just got to finish up the flap set up, glue on intakes and ill be ready.
do you think 200mm would be about neutral on CG? I ask because i did a test flight on one for a friend bout a month back and it was way nose heavy i had to yank the elevator to get it off the ground, it was supposed to be balance at what the manual recommended.

thanks!
