Sorry i have no pictures. I have time on this engine and on this air frame but not together. First thing I would say is you got way to much tank. You only need 12oz or less with the DLE20. It's going to Burn a LOT less fuel than a 1.20 glow. Also, I would never put the tank behind the CG. You are going to balance it empty. Adding weight behind the CG is going to be a problem.
As motor mounts go. I've mounted a few DLE20s on the Great Planes adjustable width mount that comes with a lot of their air frames. I've never had an issue with them lasting. When you install them however you have to cut away the center section and make them two separate beam mounts. If not the rear carb will force you to stick the engine way out and you will never get the right distance from prop washer to firewall. Speaking of firewall. You are probably going to make a hole in your firewall for the carb to fit into. No biggie really but the carb really takes a lot more room than you think. Also plan on mounting the DLE inverted even though the plane normally uses a side mount.
Finally, the first batch of Funtana's had a servo wing mount issue and many were lost. On the first batch the ply servo tray was only mounted to the spar and one rib and would flex,flutter and explode. 2nd gen kits had the tray mounted on all 4 sides.

Best wishes, David
