Actually the nose of the plane is the strongest part. It is very thick plastic up where I mounted the firewall. To install the servos I just screwed a couple of peices of wood to the sides of the bat. One problem I ran across is banding the wing to the fuse. The first time I did it the fuse started to bend so I had to install the side supports (wood). Some of the pushrods are metal and some are that thin plastic. I just used whatever I had laying around so I didn't have to buy anything new. You can see in the picture were the reciever sits, in the picture I don't have the battery in there and it isn't wrapped in foam. With all of that in there it fits prettly tight. I actually have to take the rudder servo arm off to put it in there when it is all wrapped up. We will see what happens. I found out that epoxy doesn't stick to this plastic very well. I was going to epoxy in the servo tray but that didn't last too long and ended up using wood screws.
