yea wife called me off after 2 hours.. but that is the progress i made in that time.. the last 2 planes i did i would have rather gone back to kit building. but this one is going smooth so far. i did see some areas where i needed to CA in the fuse area. when you open the canopy your like WOW. there is some nice lazer cuting in there and it is OPEN . i was contemplating puting my tank over the cg but the only thing in the fuse that blocks anything is the wing tube and it is smack dab in the way. if you put it behind the tube you will run into the same problem as the F90. as it runs out of fuel it will gain nose weight . so im just going to but the back of the tank against the front of the tube. I am also going to wait and balance it to see weither im going pull pull or in the tail rudder servo. I bet mike has run his with a YS-110 on the prototype he can tell me before i get there,HE HE.. I see he is contributing to this thread
