J Dubya, again, I thank you for the most generous offer. I had thought of cutting it down, but would like to swap back and forth to experience the differences.

Matt, but that one night out costs you days in recuperation.

Brian, in regards to your Qs
#1 my fuel lines come out under the tank.
#2 my engine mount ended up flush with the side of the fuse. On three degrees the spinner is centered. I did have to elongate the mount holes to attain that side offset.
#3 I will offer you the rule that I always follow. I do not maiden my own planes. I always (even though this is #4) start with recommended CG and control throws. I would rather be able to bring it home and make adjustments, as tedious as they are, than find out its a handful in the air.
#4 On the fuel tank, if you can figure out how to keep the Velcro from coming off the fuel tank, then go for it. I made two small light ply spars, which are removable, to hold mine down. Pics in past posts.
#5 My battery and RX are stacked by the trailing edge. All is in the compartment. All models are different. Its a balancing act.
#6 I use Dubro push rod exit grommets with the flang filed off and a piece of fuel line through it to protect the wire. More substantial than the antenna exit grommets by Dubro, but they do work. Joe
