Tideflyer --
My PNP Pulse balanced perfectly, and I epoxied the tail surfaces on, and also used the bolts. You might want to have someone else take a look at it for you.
I marked the CG location on the fuse, and just used my fingertips to check the balance. Olny took a minute to do it, and I didn't use a balancing machine, just 'cause I didn't want to take the time to get it down and put it together.
Mine flies great.
