Last weekend I got another five flights on my #1 Eclipse. The plane is not trimmed. I'm ready for the 2004 Pattern wars. I've got some inspiration to continue building my #2 Eclipse. Below are some photos of how I install the chin cowl. It's a tight fit to clear the OS140 EFI fuel injected carb, but.................it can be done. I use #4-40 soc. hd. cap screws with Loc Tite.

Picture #1 - This is the hard 1/8" plywood plate after it has been epoxyed in the fuse engine bay.
Picture #2 - This is the finished hold down plate with the OS 140 EFI engine installed. I have never had a problem with the carb touching the fuse when I leave the 1/8" clearances as shown.
Picture #3 - This is the chin cowl hold down plate. Please remember to trim to clear the carb.
Picture #4 - This is the chin cowl trimmed and mounted. The #4-40 soc hd cap screws must be cut to length to not interfere with the EFI carb.

Good luck.
