RE: excellron 90
that YS 120 should hall that baby around like no tomorrow.
I have one finished and one in a box, it is interesting to note that several builders found the need to add weight or relocate the battery to get the correct CG. I find it interesting that the above poster only needed a 1/2 oz in the rear. I wound up putting my 5 cell Ni-Mh battery just in front of the horizontal stab. That's shifting 5.2 oz's to the rear to get a 7.5" CG setting. Is the YS 120 that light? Can't imagine that.
I did not move the tank to the CG line.
Keep us posted o your experience with this.
I'm temporarily set back with family medical issues, but will be in the air soon.
